What new in Contact lenses?
Disposal times for Contact lenses
One problem with soft contact lenses is that proteins and lipids — which are naturally found in tears — adhere to the surface of the lenses, sometimes causing discomfort and providing hiding places for infection-causing germs.
lenses-cleaning products help. But over time buildup still occurs, necessitating lenses replacement. Disposable lenses, first introduced in 1987, address this problem in different ways. (Note that, although "disposable" generally means single-use, this is not not always true regarding contact lenses.)

Other types of Contact lenses
Colored lenses Many of the types of lenses described above also come in colors that can enhance the natural color of your eyes — that is, make your green eyes even greener, for example. Or these lenses can totally change the eye's appearance, as in from brown to blue. [More about colored lenses.]
Special-Effect lenses. Also called theatrical, novelty, or costume lenses, these take coloration one step further to make you look like a cat, a zombie, or another alter-ego of your choice. [More about special-effect contacts.] |
Prosthetic lenses. Colored contact lenses can also be used for more medically oriented purposes. People with disfigured eyes, as a result of accidents or disease, can use a custom, opaque colored lenses to mask the disfigurement and match the appearance of their normal eye. [More about prosthetic contacts.]
UV-Inhibiting lenses. Today, many contacts incorporate an ultraviolet blocker in the lenses material, to cut down on UV light that can eventually cause cataracts and other eye problems. You can't see this blocker by looking at the lenses. And since contacts don't cover your entire eye, UV blockers cannot substitute for traditional sun protection like good quality sunglasses.
Hybrid lenses. One brand of lenses features a GP center with a soft outer skirt, providing wearers with both the crisp optics of a rigid lenses and the comfort of a larger, soft lenses. |
