Contact Lenses and Your Eyes

A Contact Lens is designed to rest on the cornea, the clear outer surface of the eye.
Contacts are held in place mainly by adhering to the tear film that covers the front of the eye
and, to a lesser extent, by pressure from the eyelids.
As the eyelid blinks, it glides over the surface of the contact lens and causes it to move slightly.
This movement allows the tears to provide necessary lubrication to the cornea
and helps flush away debris between the cornea and the 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 the retina, the
layer of nerve endings in the back of the eye that converts light to electrochemical impulses.
When light is not focused properly on the retina, the result is blurred or imperfect vision.
When in place on the cornea, the contact lens functions as the initial optical element of the eye.
The optics combine with the optics of the eye to properly focus light on the 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 the 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 the eyeball is too short;
that is, shorter from front to back than is normal.
In some cases, hypermetropia may be caused by the cornea having too little curvature.
If you've ever worn an ordinary products, you know that deposits can build up on the surfaces
and cause cloudy vision and that scratchy, uncomfortable feeling.
But an ACUVUE eliminates the 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.
