Remember that contact lenses are medical devices that require a commitment to proper wear and care by the wearer. If not used correctly, all contact lenses can increase your chance of an eye infection.
The best way to ensure safety when using contact lenses is to see an eye care professional first. An ophthalmologist can measure your eyes for properly fit contacts, assess whether or not you are a good candidate for contacts, and offer safety tips. After you have been to an ophthalmologist and received a prescription, be sure to only buy costume contacts from retailers who require a prescription to purchase the lenses and who only sell FDA-approved contact lenses. Packaging that claims 'one size fits all' or 'no need to see an eye doctor' is wrong.
Non-prescription costume contacts can cut, scratch and infect your eye if they don't fit exactly right. They should be customized and tailored to each individual. Mis-sized lenses can cause corneal abrasions , corneal ulcers and potentially blinding painful bacterial infections like keratitis. Costume or theatrical contact lenses also might let less oxygen through to the eye, because the paints and pigments used to add color make the lenses thicker and less breathable.
Treating these injuries can require eye surgery, like a corneal transplant. People have been blinded by costume contact lenses. There are no comprehensive studies of how many injuries costume contact lenses cause. However, we hear anecdotally from ophthalmologists that they see contact-related injuries each year despite FDA regulations. These retailers are breaking the law. Here are some things you need to know about colored contact lenses before giving them a try.
The only real difference between regular contact lenses and colored ones is the color itself. Colored lenses have clear counterparts designed the exact same way. Some find them slightly less comfortable as they may be a bit thicker, but the difference is usually negligible. Also, the advantage to a thicker lens is that it can be easier to insert and remove.
These lenses come in a wide range of powers, so whether your eyesight is perfect or requires significant correcting, you can change the color of your eyes with contacts. Never share contact lenses with others. Rub and rinse your contact lenses with contact lens disinfecting solution—never water or saliva—to clean them each time you remove them. Even if worn occasionally, contact lenses must be disinfected and stored in new solution at least every 7 days.
Never store your contact lenses in water. Replace your contact lenses as often as recommended by your eye doctor. Replace your contact lens case at least once every three months. Use only fresh contact lens disinfecting solution in your case—never mix fresh solution with old or used solution.
