Have Astigmatism And Ready To Try Extended Wear Eye Contacts? ACUVUE Oasys Toric Contact Lenses May Be For You

By David Long

If you are seeking extended wear contact lenses for your astigmatism, and especially if you are suffering dryness and discomfort from your current eye contacts, ACUVUE Oasys For Astigmatism is a toric contact lens product you will enjoy.

ACUVUE Oasys toric lenses are very similar to their cousins, ACUVUE Advance For Astigmatism, and are made by parent company Johnson and Johnson. Both offer disposable wear technology and may be worn for up to two weeks with daily cleaning. ACUVUE Oasys, however, is also approved by the Food and Drug Administration for non-stop and overnight use of up to six days.

ACUVUE Oasys uses an advanced silicon polymer compound called Hydraclear Plus. It is a very moisture rich substance found inside and outside of each lens. The polymer maintains a high moisture level because it is mostly made up of water-loving long-branch molecules. The result is a soft, super-smooth feel every day and night that the lenses are worn. They are so smooth that it is easy to forget you are wearing them, even in challenging environments or if you tend to suffer from dry eyes.

These toric contact lenses are also highly permeable, which is absolutely vital for any extended wear eye contacts. Breathability is essential for your eye, since the eye needs oxygen in order to function properly. Hydraclear Plus permits an incredible 98% of available oxygen to permeate through the lens down to your cornea.

ACUVUE Oasys astigmatism lenses also offer almost total protection against ultraviolet rays. UV protection matters because the sun's UV rays can harm your vision. ACUVUE Oasys lenses give up to 96% protection against UV-A, and almost 100% protection against UV-B. That is much better than the relatively paltry 10% and 30% protection respectively offered by some other brands!

Astigmatism contact lenses must remain motionless in place on the eyeball rather than float around, because their shape and position counter the scattering of light that astigmatism causes. ACUVUE Oasys lenses counter astigmatism through advanced toric lens engineering its makers call Accelerated Stabilization Design. The design minimizes contact between the eyelid and the lens when the eye blinks, and also harnesses pressure caused by the eyelids themselves to keep the lens where it belongs. ACUVUE Oasys lenses have four stability zones instead of a single heavy "ballast" zone at the bottom of the lens as found on most other toric lenses, which results in enhanced stability and clear vision.

You should consult with your doctor and discuss whether extended wear toric lenses are a good option, since everyone's opthalmic needs are different. If your doctor agrees you are a candidate for extended wear, then you'll be glad you gave ACUVUE Oasys a try.
