What Is The Cause Of Dry Eyes

The dry eyes cause can come from many environmental aspects, aging, contact lenses and some eye health problems. If you find yourself with a problem with your eyes, you should consult a doctor if you have not figured out why this is occurring. You might need special medicated eye drops or some other type of help with the problem. If it is environmental, you might need to change the way you do some things.

Environmental conditions can cause dry eyes. If you spend time in the sun without sunglasses or some other form of eye protection, you can dry the cornea, which in turn is a dry eyes cause. Windy days can cause debris and other particles to blow into your eyes, thus wearing eye protection in needed. The heat from a hair dryer, sitting in front of a fan and driving with your window open can cause the dry eye problem. You need to be aware of your surrounding to protect your eyes from drying out and becoming irritable. This will cause itching, which can scratch the inside of the eye.

Another dry eyes cause is aging. In some adults, aging gradually causes the tear ducts to slow down or stop producing tears, which will dry the eyes. This medical condition needs to be taken care of by a doctor. The optometrists will perform a dry eye test to see the extent of your condition. You might have to use special medicated drop to keep your eyes moist. This will usually continue for life. Some babies are born without tear ducts functioning properly and need special drops to keep the eyes moist to prevent vision problems that results from lack of moisture in the eyes.

Dry eyes cause does not stop with environmental and aging, it also can come from wearing contact lenses. If you wear hard contact lenses, your eyes more than likely dry out from lack of oxygen getting behind the contact. If you wear soft contact lenses that contain more water than others do, they tend to evaporate quicker and cause oxygen to stop reaching the cornea behind the contact. If you wear contacts, you need to use proper contact solution and eye drops to keep the contacts moist as well as the eyes.

As you can see, dry eyes cause come from many different things and no one is completely free from dry eyes. If you have problems with dry eyes for a long time, you do risk having serious problem with your eyesight including, but not limited to, blurred vision, loss of vision and content itching of the eye. If you have dry eyes, it is important to seek medical advice. Your vision is a sense that you need, if you neglect the signs and symptoms you could risk this valuable sense. There is help for many eye problems and dry eyes can be helped.

Is LASIK Right For You?

Your lifestyle is one of the most important factors to take into account as you consider whether or not LASIK is right for you. Individuals consider the option of LASIK for a variety of very personal reasons. While LASIK does not promise perfect vision, it does hold the promise of reducing one's dependence on contact lenses or glasses, which will allow many people to more freely pursue their hobbies, sports activities or career options.

Realistic Expectations

LASIK is an unbelievable advancement in technology and offers a great solution to poor eye sight for some people, but do not forget it is not for everyone! Some doctors ignore this fact, but a good laser eye surgeon will discuss your long term vision options with you. A laser eye surgeon should be able to determine if you're a good candidate by discussing your lifestyle, needs and goals, and overall health. Next, you should be put through Advanced Diagnostic Testing which will determine if your eyes are a good candidate for LASIK.

Some people think that LASIK will provide them with "perfect" vision. If your goal is to achieve "perfect" vision, then LASIK might not be right for you. While it is reasonable to expect greatly improved vision and a reduced dependency on glasses or contacts, it is not reasonable to expect that you will have "perfect" vision. In general, the results of LASIK surgery - how well a person sees after the procedure - will usually be comparable to how well they were able to see before the procedure with glasses or contacts. However, every patient heals differently and results may still vary. In the end, most patients are very happy with the procedure and recommend it to their friends. If you have realistic expectations about laser vision correction then you are likely to be very satisfied after LASIK.

General Criteria For A Good LASIK Candidate

According to the U.S. Food & Drug Administration, you may be a good candidate for LASIK if you meet the following criteria:


o You should be at least 18 years old (21 for some lasers), since the vision of people younger than 18 usually continues to change.

o You should not be pregnant or nursing, as these conditions might change the measured refraction of the eye.

o You should not be taking certain prescription medications, such as Accutane® or oral Prednisone.

o Your eyes must be healthy and your prescription stable. If you are nearsighted, you should postpone LASIK until your refraction stabilizes, as nearsightedness can still increase in some patients until their mid- to late-20s.

o You should be in generally good health. LASIK may not be recommended for patients with diabetes, rheumatoid arthritis, lupus, glaucoma, herpes infections of the eye, or cataracts.

o Understand what your expectations are for the procedure. Are they realistic?

Most common reasons why LASIK is not right for almost 30% of people

o Unrealistic expectations (not satisfied with anything less than "perfect" vision)

o Eye health issues

o General health

o Thin corneas

o Unstable prescription

o Pre-cataract

o Prescription too high or too low

Advancements in LASIK technology have made it possible for many people to greatly reduce their use of contact lenses and glasses, in some cases entirely. Learning more about LASIK will give you realistic expectations for the procedure, and is a good approach to your long term vision needs. Unfortunately not everyone is a good candidate for laser eye surgery. The best way to determine if LASIK is right for you is by discussing your options with an eye care specialist in your local area.

Flattening the Recalcitrant LASIK Flap Fold & Epithelial Ingrowth After Lasik

Lasik flap folds can induce irregular astigmatism with optical
aberrations and loss of BCVA especially if they involve the visual
axis. 'Macrofolds' are easily seen by slitlamp exam and represent full
thickness flap tenting in a linear fashion. On the other hand,
'microfolds' within the flap itself may represent wrinkles in Bowman's
layer or in the epithelial basement membrane. They are best seen as
negative staining lines with sodium fluorescein. The incidence of
folds requiring intervention ranges between 0.2% and 1.5%.

Flap folds result from uneven alignment of the flap edge and the
peripheral epithelial ring. This can occur with unequally hydrated
stromal bed prior to flap repositioning. Thinner and larger flaps tend
to shift more readily with resultant surface wrinkling. Uneven sponge
smoothing can result in radial (with centrifugal movement) or
circumferential folds (with centripetal movement). A higher incidence
of flap folds is usually found in higher myopes and is sometimes
unavoidable. This is due to the reduced central convexity and stromal
support resulting in flap redundancy that may be quite difficult to
flatten.

Management ranges from simple lifting and refloating of the flap to
placement of sutures to stretch the flap in position. Probst et al.
described a technique using the red reflex as a way to better detect
flap wrinkles during flattening procedures. Smoothing of the flap
should aim towards an even distribution of forces applied to the
surface. This can be performed with methylcellulose sponges or their
equivalent. Instruments such as the Pineda corneal LASIK iron can also
be used to flatten isolated flaps at the slit lamp or under the
operating microscope by gently pressing on them. Other reported
strategies include hydrating the flap with hypotonic saline (60-80%)
which may facilitate leveling of the flap surface.

Fixed folds are sometimes encountered and probably occur when
epithelial hyperplasia has time to form in the crevices formed by the
folds. Superficial epithelial incisions or frank epithelial debridement
over the wrinkled area may relieve contractures that occur secondary to
the presumed epithelial hyperplasia in these longer standing folds.
Recalcitrant wrinkling is reported to respond well to placement of
running torque-antitorque 10-0 or 11-0 nylon sutures.

Epithelial Ingrowth after Lasik


Epithelium in growth under the corneal flap can cause irregular astigmatism
and induced hyperopia secondary to stromal melting. A swift
intervention is sometimes needed to prevent these complications.

Once the epithelium is noted to progress towards the visual axis or
once a significant hyperopic shift or loss of BCVA is encountered,
lifting of the flap and scraping of the epithelium should be performed
promptly. This can be performed with a #69 blade or the equivalent. It
is important to remember to scrape both the stromal bed as well as the
stromal aspect of the flap. Flap folds connected to the peripheral
epithelial ring are a special source of concern as they provide a
conduit for epithelial cells infiltration. Similarly, an epithelial
defect adjacent to the edge of the flap should be followed closely due
to the presence of high epithelial mitotic activity.

Which epithelium is safe to leave? Small epithelial pearls are usually
self-limited and do not progress. Epithelial tongues connected to the
flap edge are more worrisome, they do not need to be scraped unless
they exhibit a quick rate of progression or if they already
involving/threatening the visual axis.

The Importance Of A Reputable Lasik Eye Surgery Center

For anyone considering Lasik eye surgery, the importance of finding a reputable and experienced Lasik eye surgery center is absolutely crucial. Just as you would never embark on a surgical procedure with doctors that you didn't know or trust, you should never entrust the health of your eyesight to random surgeons you find in the yellow pages of the phone book.

In order to get what you need from Lasik surgery – in a safe and effective way – you must find a surgical center that extends quality, dependability, experience, and professionalism to their patients – at all times.

Lasik eye surgery – for the uninitiated – is a refractive procedure that works to correct the way in which our eyes refract light. When light is captured by the lens of our eye – the portion of the eye located directly behind the iris, or colored part of the eye – the lens refracts, or bends, the light to be then captured by the retina, a group of cells in the lining in the back of the eye.

The retina then takes those light signals and converts them into messages that can be understood by the optic nerve in our brain. When there are refractive difficulties in our eyes – through nearsightedness, farsightedness, or astigmatism – the light is not refracted to the retina properly and the brain receives a message of a blurry image.

During the Lasik procedure, a laser is used to resurface the cornea – the thin, transparent covering that blankets the iris and lens of the eye – thus clearing the way for refractive clarity. Lasik is generally a painless procedure that can be performed in mere minutes. Skilled surgeons who work within a Lasik eye surgery center and perform this procedure on a daily basis are in the best position to assess your candidacy for the procedure and what will work best for your eyesight.

Begin your search for a Lasik eye surgery center by looking in your immediate area; logistical convenience should be your first consideration but it shouldn't be your only one. Speak to people who have had the procedure performed in your area in order to get a sense for the more popular and reputable surgery centers.

If you are interested in a particular Lasik eye surgery center, then speak to patients who have had the procedure performed in that center and who are willing to share their experience. Finally, visit the centers in which you are interested to assess their organization, patient care including pre-operative and post-operative care, cleanliness, professionalism of the staff, and financial options available to you.

Once you have decided on a Lasik eye surgery center it is important to then research the surgeons who work within the center and who will be assigned to your case. With the assistance of the Internet it does not take very long to investigate the education, experience, and reputation of any surgeon in which you are interested. Meet with the surgeon yourself to get a feel for his/her standard of care and what systems they put into place to ensure your comfort and successful outcome.

Product Review - Creative Zen Vision - M 60 GB Portable Media Player

Apple basically owns the portable media player market - some sources quote it as enjoying well above 50% market share, while competitor Creative has a meager 2-3%. Still, that hasn't stopped Creative from trying - their Zen Vision: M 60GB Portable Media Player presents the consumer with an alternative to the iPod not to be ignored.

On the surface, it's shaped like an iPod, equally tall but about a few mm thicker. All the controls are on the top surface and the touch interface allows one to scroll through songs and folders easily and quickly. It's pretty easy to navigate the Zen Vision common-sense system, but it does lag at times, especially with videos.

Audio is high quality, and the volume is strong and distinct. It only supports MP3, WMA and WAV audio formats though. Playlists are better than with older Zen models I've tried, you just add tracks to a queue and then call it a list. It lets you choose to listen to random tracks, albums, and frequently or rarely played tracks. The quality of any format played is outstanding regardless of your speakers, too.

If audio was good, video is great especially when compared to other media players. The Zen supports DivX, XviD, WMV9 and MPEG so all those XviD and DivX files you downloaded can be watched without extra converting. The LCD is crystal clear and bright, great for watching all the TV shows and movies you've got.

You also get to store all the photos you want in the Zen - standard .bmp, .png, .tiff and .gif formats all convert to jpeg automatically on upload. Pictures can be rated, rotated, zoomed in and set as wallpaper - once you choose a wallpaper you get to adjust its brightness and change the color settings to suit your style.

For all file uploads, the Zen uses its own Zen Media Explorer as the tool for uploading stuff, ripping, and converting formats. Looks a lot like the basic Windows folder interface and it's pretty straightforward, but it only works on Windows XP and doesn't support UMS.

Battery life is pretty good. You could watch about 2-3 hours of video with one charge, with practically no heat coming off when you're enjoying your videos.

So should you buy the Creative Zen Vision: M 60GB Media player?

It has great video and audio quality, a convenient and easy-to-use navigation for both its media upload tool and in the player itself, and has a nice, bright screen - but it's only for the Windows XP, and it lags a bit at times. Definitely not for the hardcore Mac users, but I'd recommend it to anyone else - a similarly priced iPod has only 30GB of space.

If you're looking to buy online, get it at Newegg.com at just $236 with free shipping after a $30 mail-in rebate, which is just about the best price online - check it out here at Pricegrabber.com. Plus, Newegg has a great return policy in the rare event that you get a defective Zen, and they'll foot all the shipping bills incurred. Over 75% of buyers there rated it 5/5 - it's certainly a good choice.

LASIK Eye Surgery vs Lens Implants for Vision Correction

Patients seeking permanent correction of common vision problems such as nearsightedness now have a choice between surgically implanted lenses, called phakic IOLs (intraocular lenses), or the traditional LASIK surgery. Both procedures work by changing the way light rays enter the eye and both procedures can help sharpen vision and greatly diminish dependency on glasses or contact lenses. The type of laser eye surgery or lens implant recommended will be based on the age of the patient, corneal thickness and the health and lifestyle of the individual.

LASIK Eye Surgery

LASIK uses energy to reshape the cornea and is effective in treating nearsightedness (myopia), but is not recommended for patients with severe vision impairment. The reshaping of the cornea in LASIK is permanent as it involves removal of tissue from the cornea of the eye, thus changing its shape. The eye surgeon uses a computer to calculate the exact amount of cornea that needs to be removed from each patient's eye, and then he creates a thin cellophane flap on the surface of the cornea. The surgeon then lifts the flap, positions the laser and delivers a pre-determined number of ultraviolet light pulses onto the newly exposed part of the cornea. Every pulse of the laser removes a microscopic layer of cornea.

When the LASIK surgery is complete the flap is put back in place without stitches so that it can adhere naturally to the treated cornea. This procedure flattens the center of the cornea, enabling light rays to be more focused and precise on the retina, thus making images more sharp and clear. Several different forms of LASIK are used today, each depending on how the flap on the cornea is created.

Lens Implants

Patients that do not qualify for LASIK because of very high myopia or very thin corneas are potential candidates for surgically implanted lenses, also called phakic IOLs (intraocular lenses). This new option offers a more permanent correction of common vision errors such as myopia (nearsightedness). These implants, which bear a similarity to contact lenses, are placed between the cornea and the iris. Some eye surgeons consider IOLs the best option for extreme nearsightedness. Unlike traditional lens implants, which typically provide clarity in either near, intermediate, or distance ranges, multifocal and accommodating lens implants offer the prospect of good vision at more than one range.

Unlike LASIK, surgically implanted lenses do not require tissue removal from the eye. The patients natural lens remains in place to focus from far to near in a natural way, it is intended for younger patients who are still able to focus well, but may also be used on older patients as long as they retain sufficient focusing ability. Convenience and reversibility are just a few of the advantages of this procedure.

Write Real, Write Now With Cross Fountain Pens

We are quickly becoming a pen-less and paperless society. In the same way that typewriters reduced the need for writing, computers have reduced the need for paper. In the past, writing a novel, filling out tax forms, or even making a grocery shopping list required putting pen to paper. Today, those same tasks can be done by putting fingers to keyboard. When ink is needed, though, it is often printer ink, not pen ink. Furthermore, if John Hancock were to put his "John Hancock," or signature, on the Declaration of Independence today, he might use an electronic pen. But the news is not all bad in the decline of ink pen usage. The personal computer era has prevented the cutting down of countless trees. Also, computers have greatly increased the efficiency of recording information. In job interviews, secretaries are rarely asked how many words-per-minute they can write. Despite the slump in ink pen usage, however, Cross fountain pens continue to keep writing more tactile, and at the same time maintain a time-honored tradition.

The Fountain of Ink


A fountain pen is filled from a source outside itself, and contains an ink supply that automatically feeds the writing tip. As early as the 900s, humans have started developing a pen that fed itself and had no need for sharpening. The mission was accomplished in 1884 when the Waterman Company created the first fountain pen. That pen worked as well as a "dipping pen" but required no ink bottles! Today, numerous styles of fountain pens are produced, but each has the same basic parts. The nib serves as the pen's point. Next, the barrel stores the ink supply. And finally, the cap covers the pen's nib, in order to protect it. What makes the ink flow steadily in a fountain pen? A force called capillary attraction keeps the speed that ink flows from its supply to the tip balanced.

The Cross Company


The A.T. Cross Company is no stranger to fountain pens. It has been creating and improving high-quality writing instruments for more than a century and a half. In fact, Cross was the first American producer of quality writing instruments. Today, the design and craftsmanship of Cross's pens continue to be world-class. The company's founder, A.T. Cross, was a master pencil and pen maker who shared his craftsmanship with Alonzo Townsend Cross, his son. As the saying goes, the more things change, the more they stay the same. Today, Cross's quality pens are handmade just as they have always been - one at a time in scenic Lincoln, Rhode Island.

The Pens


Like all of their products, Cross fountain pens are truly masterpieces, revealing several features that add value to the instruments. For instance, all that glitters is gold on Cross fountain pens. Some of their high-end fountain pens include gold caps, nibs, and barrels. The numerous layers of clear lacquer allow other Cross fountain pens to look as sleek as today's Italian sports cars. Moreover, if you want a pen that looks flashier than the standard U.S. government-issued writing instrument, you can choose a Cross fountain pen from nearly every color found in a bag of Skittles candy. On the other hand, if you prefer strength to aesthetics, choose a Cross fountain pen that has been plated with rhodium, a very hard metal.

Today, with the advent of computers and the Information Age, Cross fountain pens remind us of how physical and personal the act of putting pen to paper can be.

Minimizing Your Need For Wheelchair Repairs

Wheelchair users are always concerned with the possibility of their wheelchairs breaking down when they have no when they are outside with no one around to help them. Those who have manual wheelchairs worry about flat tires, and those with motorized chairs have to think about not only flat tires, but also failing batteries. All of them, however, could minimize their chances of such bad luck by taking advance precautions to let them recover, should one of these difficulties arise.

The thought of a disabled person being able to perform an instant wheelchair repair may seem a bit far-fetched to some. But there are safety measures which wheelchair users can implement to help them through a breakdown even when they are on their won; a cell phone, for example, will guarantee that even if you have no help when your breakdown occurs, you will have some very soon thereafter.

Simple Safety Measures

Having a cell phone with you will enable you to get in touch with your wheelchair repair service or to call a friend or family member. But there are other safety precautions you can take; spare batteries for your motorized chair can be carried in a backpack; and if you are partially mobile, having a pair of crutches or a cane on hand can help you enough that you can get real help. Having your doctor's and insurance company's phone number, in case your wheelchair is covered for the cost of repairs, is also a good idea.

Heading Off Trouble

Periodically run a "diagnostic" on your wheelchair to spot any incipient problems: have one done at your wheelchair repair center about every six months. It's one way of heading of trouble before it has you stranded on your own after a breakdown. It will also keep your wheelchair performing at its best because the failure of one part, if left untreated, can often have a domino effect and send your wheelchair into a tailspin.

Being disabled is not fun under the best of circumstances; it can leave you feeling both frustrated and helpless. But there are things you can do to take control of your situation, and by being smart and preparing ahead of time, you can manage any unexpected occurrences without losing your cool.

It's your decision whether or not you let your disability really disable you, or become proactive in your approach to life. When you know how to prepare yourself for unexpected emergencies, you'll have the peace of mind you want and can focus your energies on living your life to the fullest.

Neways MLM Home Business Review

Neways International is a wellness based company with its world headquarters located in Springville, Utah. Neways offers a home business opportunity by selling or marketing their products through MLM or multilevel marketing.

The Neways product line consists of a vast array of products. They include Animal/Pet care, Aromatherapy, Autocare, Cosmetics, Haircare/Hair Accessories, Health/Fitness/Wellness, Nutritional Supplements, Oral Hygiene, Personal Care, Skincare, and Weight Management products. Some testimonials that have been given by individuals that have consumed Neways products include statements of relief from headaches, arthritis, and other health related symptoms.

The Neways business opportunity contains a hybrid unilevel payout plan system with a stairstep-breakaway payout system. This is one of the hardest comp plans to understand as well as explain. A big part of the stairstep-breakaway part is that when a distributor reaches a certain qualifying point, they then breakaway from their original sponsor. When this happens, generally the original sponsor will now only get a certain percentage of everything the sponsored distributor's group is doing. When you take a look at the industry average, the Neways compensation plan is not a bad comp plan, but each individual should be prepared to recruit.

In conclusion, Neways seems to have a decent product line and the compensation plan would rate out as a fair in the MLM industry. If you don't mind having to get an average of 100-200 people on your team to make a $1000 residual check each month (which is pretty true with any MLM opportunity), then the Neways business might be a good fit for you.

The Difference Between Ready Readers And Prescription Reading Glasses

The most fundamental difference between these models and prescription reading spectacles is that they have the same prescription for each eye/lens, generally +1 - +3.
Prescription reading glasses are customised to each individual and each eye, and often contain a different prescription for each. They can also correct astigmatism if required.

The "Ready Readers" are made in bulk and do tend to be very cheap. The manufacturing process means that the frame is made in one piece, and so cannot be reused or have the lenses changed if any difficulty occurs such as a crack in the lens or a change in prescription. Even the higher quality Ready Readers which may be made with metal frames do not have screws and so cannot be changed or easily adjusted.

Prescription glasses and frames can be reused if your prescription alters. The lenses are centred in front of your eyes with the PD (Pupillary Distance) , whereas RR are centred in the middle of your frame. Also prescription is by definition more accurate.

Because the strength of the lens in Ready Readers is an approximation (and frequently self-diagnosed), they tend to be less accurate and can cause eyestrain – although this will not cause any lasting damage to your eyes, it can become uncomfortable if using the glasses for extended periods

Overall, if you are fortunate enough that both eyes have the same prescription, it is probably worth at least purchasing some "off the shelf" ready readers for back up - but it is alwys worth considering also prescribed reading glasses to make sure that you take best care of one of your most valuable assets.

Coastal Vacations Review

Coastal Vacations is a travel-based company with corporate headquarters located in Kissimmee, Florida. Coastal offers a home business opportunity by selling or marketing their vacation packages through the direct selling industry.

The Coastal Vacations product line consists of many different vacation packages that offer travel to select destinations around the world. The business opportunity consists of marketing these vacation packages for a starting price tag of $1295.

The Coastal Vacations business opportunity has a 2-Up compensation plan attached to it. The payout is $1000 for every $1295 sale made by the qualified affiliate. The issue with the compensation plan is the requirement of two sales (hence 2-Up) before commission can be earned. To get started with Coastal, a new person must pay $1295 to become a representative and then give up $2,000 ($1000 x 2) from their first two qualifying sales to their qualified sponsor. This means they must give up $3,295 before they can earn any money with the program. Another issue with Coastal Vacation's 2-Up program is that if you bring in someone who makes a sale or two per day, you only get their first 2 sales and then you no longer get paid on their efforts. They then breakaway from their sponsor and actually end up becoming their competition. This doesn't give the qualified Coastal sponsoring associate much motivation to help the new associate since they will ultimately become competition.

In conclusion, Coastal Vacations seems to offer a decent selection of vacation destinations, but the comp plan leaves more to be desired. Some people do well with a 2-Up program, but most struggle. If you are an experienced internet marketer and don't mind shelling out over $1000 as well as having to pass up your first 2 qualifying sales, then the Coastal Vacations business opportunity might be an okay fit for you.

How Do Glasses Correct Sight?

1. Hypermetropia (long sightedness)

Hypermetropia occurs when light focuses behind the retina. It is caused by the eye being too short or the cornea at the front of the eye being too flat and not focusing light as efficiently.

Hypermetropia is corrected by a convex lens which converges light rays into the eye to bring the focus forward on to the retina.

2. Myopia (short sightedness)

Myopia occurs when light focuses in front of the retina. It is caused by the eye being too long or the cornea at the front of the eye being too steep and focusing light too efficiently.

Myopia is corrected by a concave lens which diverges light rays into the eye to move the focus back to the retina.

3. Astigmatism

Astigmatism sometimes occurs when light focuses unevenly at the retina. It is caused by the cornea or crystalline lens of the eye being "rugby ball" shaped.

Astigmatism is corrected by a cylindrical spectacle lens (cyl)

4. Presbyopia

Presbyopia occurs when the crystalline lens in the eye loses its ability to change shape. This means that objects which are close up cannot be focused on the retina properly but objects in the distance can be.

Presbyopia is corrected by a convex lens which is only used for near viewing. It is sometimes corrected by bifocal or varifocal lenses when distance glasses are also required.

Celebrity Trend - Baby Blue Colored Contacts

Celebrities like Paris Hilton create their own brand by identifying themselves with a certain look—in her case, baby blue colored contacts. If you didn't know better, you'd think that Paris had naturally blue eyes instead of brown.

So, thinking of creating a "brand" of your own? Most of us don't want to go that far, but maybe having a little fun with eye color isn't such a bad idea. Baby blue colored contacts are a popular choice for you to try. The brand you choose depends on contact lens prescription from an eye doctor. Eyes come in all shapes and sizes so not all colored lenses fit the same. You must have an eye exam and be fitted for contacts to ensure the best comfort and health for your eyes, but once you have your prescription, you can shop around to find the best deal. The brand you choose also depends on your natural eye color, and whether you are trying to completely change color or just update your look.

Changing a dark eye color to baby blue, for example, requires an opaque contact lens. Opaque lenses have a solid colored portion that covers the iris so that none of the natural color shows through. If you want to completely change your eye color, opaque lenses are for you. Acuvue 2 Color Opaques are a good choice to try for disposable contacts. Natural Touch brand from CooperVision are more expensive extended wear lenses with a longer replacement schedule.

If you have light colored eyes, like blue, gray or green, you can intensify your natural eye color with enhancer contact lenses. Enhancers use translucent color to cover the iris, so the wearer's natural eye color can still be seen. For baby blue color enhancing contacts, try disposable Acuvue 2 Enhancers or FreshLook Dimensions.

Variations of both opaque and enhancer colored contacts include a limbal ring, or dark outer ring that defines the iris. Impressions Colors in blue for both light and dark eyes feature a limbal ring. As well, Natural Touch in baby blue features the same dark outer ring.

Here's a quick list of baby blue contact lenses for you to try:


  • Impressions Colors in blue

  • Illusions in soft blue

  • Natural Touch in baby blue

  • Durasoft 3 Colors in baby blue
