The primary drawback to wearing contact, especially for children, is the requirement that they be cleaned and disinfected daily in order to prevent an infection, which could result in permanent damage to the eye. Careful choice of lenses and consistent lens care will minimize the risk of infection. Wearers of best lenses are the least prone to infection but the lenses are much less comfortable, more expensive, and can pop out of the eye more easily than lenses. Daily wear lenses put the wearer at a slightly higher risk of infection because they absorb more external liquids and airborne contaminants. They are flatter and lighter than conventional lenses.There are many lenses and lens-coating options for individual needs, including coatings that block the ultraviolet (UV) light or UV and blue light which have been found to be harmful to the eyes. Such coatings are not needed on polycarbonate lenses, which already have UV protection. UV coatings are particularly important on sunglasses and ski goggles. Sunglasses, when nonprescription, should be labeled with an indication that they block out 99-100% of both UV-A and UV-B rays. There are anti-scratch coatings that increase the surface hardness of lenses (an important feature when using plastic lenses) and anti-reflective (AR) coatings that eliminate almost all glare and allow other people to see the eyes of the wearer. AR coatings may be particularly helpful to people who use computers or who drive at night. Mirror coatings that prevent other people from seeing the wearer''s eyes are also available. There is a whole spectrum of tints, from light tints to darker tints, used in sunglasses. The lenses Council reports that 26 million Americans wear contact. Among lenses wearers, approximately 80% wear the soft type and 18% wear rigid gas-permeable lenses. The Council reports that about 11% of lenses wearers, approximately 2.8 million people, are under 18.InfantsThere are few instances when corrective lenses--lenseses or contacts--are prescribed for infants. However, when an infant develops cataracts , a condition known as infantile aphakia, contact may be prescribed following surgery. In 1993, the Journal of the American Medical Association reported that contact were safe and effective for use with infants following cataract surgery. Routine care of the lenses was easily learned by the baby''s parents or caregivers.
