Retaining Good Vision in Middle Age

Are you over 40 and finding it more of a challenge to read small print? You might be developing presbyopia, a common condition affecting those reaching middle age. But, this doesn't mean that those who already wear prescription eyeglasses for nearsightedness need to own two pairs of glasses. Multifocal lenses let you see clearly all the time, tending to both issues with just one pair of glasses.

Multifocals are a vast improvement on bifocals. Bifocals do fix poor near and far vision, but left everything in between a little blurred. In an effort to rectify this problem, progressive lenses were invented, which give you and intermediate or transition part of the lens that allows you focus on the area between things like the books you read and far objects like road signs. How does this work? Well, progressive lenses are specially curved, unlike a bifocal lens, which is harshly sectioned. For this reason, progressive lenses are also known as no-line lenses. This creates not just better vision at all distances, but also nice, comfortable transitions in between.

Progressive lenses, although better, may take some time to adjust to. While the gentle lens curve is more elegant, the lens's areas of focus are small, so that there's also room for transitional areas.

While these days, these progressive lenses (sometimes called trifocals) are for presbyopia, bifocals are still used to help young patients who suffer from eye problems such as eye teaming, or being unable to focus while reading, which causes headaches.

Although it may appear to be an easy solution, it's best to steer clear of drug store bifocals. Most of these ''ready-made'' glasses have the same prescription in both lenses, which will not help a lot of people.

Wearing a wrong prescription can lead to headaches, eye strain or even nausea. Unfortunately, presbyopia is a reality of aging. But keep in mind that multifocal lenses can make all the difference.
