Some people enjoy making a fashion statement with eyeglasses, while others prefer their appearance without them. Contact lenses can achieve freedom from eyeglasses without irreversible refractive surgery. Contact lenses can also provide a full field of unobstructed vision, which is great for an active lifestyle. Today’s contact lenses are designed to be very comfortable.

Contact Lens Materials:
- Soft lenses are made from gel-like, water-containing plastics, and are most common.
- RGP lenses or “oxygen permeable” lenses are made from rigid, waterless plastics and are especially good for presbyopia and high astigmatism.
Disposable Contact Lenses
Soft lenses have these general classifications, based on how frequently they should be discarded:
- Daily disposable lenses – Discard after a single day of wear
- Disposable lenses – Discard every 2 weeks
- Frequent replacement lenses – Discard monthly or quarterly
- Traditional (reusable) lenses – Discard every six months or longer
How They Work…
Contact lenses are thin transparent plastic discs that sit on the cornea. Just like eyeglasses, they correct refractive errors such as myopia (nearsightedness) and hyperopia (farsightedness). Contact lenses are shaped based on the vision problem to help the eye focus light directly on the retina.
On the surface of your eye there is a layer of tear fluid, this fluid is what keeps the contact lenses in place. Eyelid pressure also holds them in place. As the eye blinks, it provides lubrication to the cornea and helps flush away any impurities that may have become stuck to the lens.
Contact lenses are closer to natural sight than eyeglasses. To allow a more natural field of vision, contact lenses move with your eye and correct the error closer to the eye. They will not obstruct your line of sight, like glasses can. Contact lenses can be worn all day, or even several weeks at a time, depending on the type of lenses your doctor prescribes.
Caring for Your Lenses
Taking care of your contact lenses is essential. Good care can extend the life of your contact lenses and protect the health of your eyes. Not taking good care of your lenses can lead to a variety of eye infections, including some that cause blindness. Also, wear your contact lenses as prescribed. Your eye doctor will recommend a wearing schedule specific to the type of contact lens he or she has prescribed. Only wear your contact lenses for the time recommended. Here are some more tips to keep your contacts as good as new:
- Wash and dry your hands before you put in and take out your contact lenses. This will eliminate the transfer of dirt and germs from your hand to the eye.
- Once you remove a lens, clean it with the solution your eye care provided recommended. Place the contact lens in the palm of your hand and rub for a few second.
- Rinse the lens again to remove the loosened debris.
- Place the lens in your CLEAN case or lens holder. Fill your case will fresh solution daily.
