Contact lens gives you a more natural vision and eliminates poor peripheral (side) vision. It puts your field of vision in focus and reduces the reflections or distortions you get from the backside of eyeglasses. With contacts, there are no weight and resulting discomfort, unlike eyeglass which need periodic tightening adjustments. You can participate in sports without the fear of your glasses falling off when you have contacts on and it doesn't get fogged up nor gives blurred vision whenever it rains.

Types of contact lenses

Rigid gas-permeable (RGP) lenses is made of slightly flexible plastics that permit oxygen to flow through to the eyes. RGP offers excellent vision and corrects most vision problems. With a short adaptation period, it is easy to put on and care for. It has relatively long life and is available for myopia and cornea refractive therapy. It is also comfortable to wear and is available in tints and bifocals. A little downside of RGP is that it requires constant wear to maintain adaptation.

Daily wear soft lenses is made of soft, flexible plastics which are combined with water. It is the water that permits oxygen to flow through to the cornea which increases comfort and reduces dry eyes. It is available in lenses that do not need to be cleaned and also in tints and bifocals. Great for active lifestyles but has very short adaptation period. It is more comfortable but doesn't correct all vision problems. Also lenses wear out and must be replaced in a timely fashion.

Extended wear-disposable lenses are soft lenses that can be worn for an extended period of about one to six days then discarded. It requires little or no cleaning and has lesser risk of infection. It doesn't correct all vision problems and it is available in tints and bifocals.

Planned replacement lenses are soft daily wear lenses that are replaced on a planned schedule, most often either every two weeks or monthly or quarterly. They are good for eye health with simplified cleaning. However, they don't guarantee sharp vision unlike RGP.

Which ever of these lenses you may prefer, it is important to practice healthy contact lens habits in order to avoid eye infections. This involves washing your hands prior to applying the lenses, putting the contacts in before applying makeup and using makeup products that are safe for contact wearers.
