Contacts are held in place mainly by adhering to tear film that covers front of eye and, to a lesser extent, by pressure from eyelids.

As eyelid blinks, it glides over surface of contact lens and causes it to move slightly. This movement allows tears to provide necessary lubrication to cornea and helps flush away debris between cornea and contact lens.

A contact is an optical medical device, primarily used to correct myopia, hyperopia, astigmatism and reading problems. In these conditions, light is not focused properly on retina, layer of nerve endings in back of eye that converts light to electrochemical impulses. When light is not focused properly on retina, result is blurred or imperfect vision.

When in place on cornea, contact lens functions as initial optical element of eye. The optics combine with optics of eye to properly focus light on retina. The result is clear vision.

Hypermetropia is not a disease, nor does it mean that you have "bad eyes." It simply means that you have a variation in shape of your eyeball. The degree of variation will determine whether or not you will need help.

What causes farsightedness? Hypermetropia most commonly occurs because eyeball is too short; that is, shorter from front to back than is normal. In some cases, hypermetropia may be caused by cornea having too little curvature.

If you've ever worn an ordinary products, you know that deposits can build up on surfaces and cause cloudy vision and that scratchy, uncomfortable feeling.

But an ACUVUE eliminates problem of long-term deposit build-up because they are never worn longer than one day.

Your vision is always sharp and clear and always comfortable.

Better still, cost of an ACUVUE disposable products is no more per day than what you might pay for a cup of coffee and a muffin.
