Some Interesting Information About Your Eyes and Contact Lenses

A Contact 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.

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

A growing number of people now use these products, which can be worn for either a single day, or up to seven, depending on the wearing schedule prescribed by your eye care professional.

Even bifocal wearers can now get discount prices when ordering.

Six per box is the average number per supplier. They are usually used for anywhere from 1 to 2 weeks on a daily wear basis and approximately 1 week if used as extended wear.

Replacing frequently usually means better eye health. Other obvious advantages are having spare ones immediately available should one get torn or lost.

Be sure you wear your back up eye glasses at least once a week to give your eyes and cornea a chance to reoxygenate.

Symptoms of overwear include burning eyes, dryness, blurred vision and seeing halos around lights.

This can lead to serious corneal problems and infections. Consult your eye doctor regularly for eye examinations and follow up care.

Frequent and Planned Replacement are replaced on a planned schedule,
most often every two weeks, monthly or quarterly. These items usually come 4 to 6 per box.

Eye care professionals may recommend enzyming them if they are used longer than one month. A popular brand is the Colored Monthly from Ciba Vision.
