Have you started to find it difficult to focus on the text in books and on computer screens? Do your eyes seems to have trouble shifting focus from close-up objects to faraway ones? You may need multifocal lenses to help you combat this problem. Progressive lenses represent the state of the art in multifocal eyeglasses -- and you can get them right here at Westchester Eye Care Center.
Progressive lenses are designed to treat a specific vision problem known as presbyopia. Presbyopia is a refractive error caused, not by the length of the eyeball or the shape of the cornea (as in other refractive errors such as nearsightedness and astigmatism), but by age-related changes in the eye's lens. As you pass age 40, the lenses of your eyes tend to stiffen, making it harder for their focusing muscles to do their job. If you had perfect vision before, you probably need help with near vision now. If you have trouble seeing distant objects clearly before (nearsightedness), you're now both nearsighted and farsighted.
Progressive lenses can correct all of these visual fields. The top portion of each lens corrects distance vision, while the bottom part corrects near vision. Connecting these two segments is a narrow corridor that corrects for all the distances in between (intermediate vision). By simply directing your eyes upward or downward, you can always have the right degree of correction for whatever distance you're trying to view.
Multifocals have existed since the days of Ben Franklin in the form of bifocal (and later trifocal) lenses. But the two or three distinct segments of these lenses have some limitations which are overcome by progressive lenses. Progressive lenses don't limit your vision to two or three zones of clarity; instead, they provide a gradation through all possible distances as your eye moves from the top of the lens to the bottom.
Once our optometrist has prescribed progressive lenses (following the necessary eye exam), you'll find that this form of eyewear takes a little getting used to. For instance, the right and left sides of the lens have no correction at all, so the brain has to learn how to "ignore" this. You also need to learn to turn your head to look directly at objects you wish to focus on.
