If you are seeking extended wear contact lenses for your astigmatism, and especially if you are suffering dryness and irritation from your current eye contacts, ACUVUE Oasys For Astigmatism is a toric contact lens product you will love.
Like their similar cousins, ACUVUE Advance For Astigmatism, ACUVUE Oasys toric lenses are made by parent company Johnson and Johnson. Both brands are disposable and may be worn for one or two weeks with daily cleaning. ACUVUE Oasys, however, beats Advance in that it is also approved by the Food and Drug Administration for non-stop and overnight wear of up to six days.
ACUVUE Oasys uses an advanced silicon polymer compound called Hydraclear Plus. It is a very moisture rich element found on the outside and inside of each lens. The polymer maintains a high moisture level because it is mostly composed of water-absorbing long-branch molecules. The result is a silky, super-comfortable feel every day and night that the lenses are worn. They are so smooth that it is easy to forget you have them on, even in difficult environments or if you tend to suffer from dry eyes.
These toric lenses are remarkably breathable, which is an absolutely vital component of any extended wear eye contacts. Breathability is crucial for your eye's health, since the eye needs oxygen in order to function properly. Hydraclear Plus allows an incredible 98% of available oxygen to penetrate through the lens down to your cornea.
ACUVUE Oasys astigmatism lenses also give almost complete protection against ultraviolet rays. UV protection matters because the sun's UV rays can damage your eyesight. ACUVUE Oasys lenses deliver up to 96% protection against UV-A, and almost 100% protection against UV-B. That is much greater than the relatively small 10% and 30% protection respectively offered by some other brands!
Toric lenses must remain motionless in position on the eye rather than float around, because their shape and position counter the scattering of light caused by astigmatism. ACUVUE Oasys lenses counter astigmatism through advanced toric lens engineering its makers call Accelerated Stabilization Design, which minimizes contact between the eyelid and the lens when the eye blinks. The design also harnesses pressure caused by the eyelids themselves to keep the lens where it belongs. This is all possible because 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. The enhanced stability results in clear vision, since your toric eye contacts should almost never pop out of their correct shape.
If you think extended wear toric lenses are for you, you should consult a doctor to make sure that your eyes can tolerate extended wear lenses since everyone's opthalmic needs are different. If your doctor says you are eligible, then you'll be glad you gave ACUVUE Oasys a try.
