Contact lenses are worn directly on the cornea of the eye. Like eyeglasses, contact lenses help to correct refractive errors and perform this function by adding or subtracting focusing power to the eye's cornea and lens.
Facts about contact lenses
Over 30 million Americans wear contact lenses, 80 percent of whom wear daily wear soft lenses. Currently, there are four types of contact lenses in use:
- The soft, water-absorbing lens
- The rigid, gas-permeable lens
- Other rigid lenses
- Other flexible, nonwater absorbing lenses
Cosmetic Safety for Contact Lens Wearers
What eye hazards may be associated with cosmetic use?
According to the American Academy of Ophthalmology and the American Optometric Association, cosmetics are among some of the most common sources of problems for contact lens wearers. Misusing cosmetics can lead to severe adverse reactions, including:
- Deposits on the lens
- Eye irritation
Reading a contact lens prescription
The prescription for contact lenses includes more information than what is available on the prescription for eyeglasses. Special measurements will need to be taken of the curvature of the eye. In addition, the doctor will determine if the eyes are too dry for contact lenses, and if there are any corneal problems that may prevent a person from wearing contact lenses. Trial lenses are usually tested on the eyes for a period of time to ensure proper fit.
The contact lens prescription usually includes the following information:
- Contact lens power (measured in diopters, like eyeglasses)
- Contact lens base curve
- Diameter of the lens
- Contact lens manufacturer
- Expiration date
Eye care specialists are required by federal law to give you a copy of your contact lens specifications.
