Multifocal Lenses and You

A lot of people start to have problems with close vision during their 40s. This condition is known as presbyopia. If you already wear glasses for distance vision, and are later on diagnosed with presbyopia, you won't have to start carrying and switching between two pairs of glasses. Multifocal lenses, which rectify both near and distant objects, let you see clearly at all times, with one pair of glasses.

Multifocals are much better than bifocals. Bifocals did correct problems with both near and far vision, but often things in between were blurry. To create something better, progressive lenses were developed, which provide wearers with a transition part of the lens allowing your eyes to focus on the area between near and far distances. How does this work? Well, progressive lenses feature a gradual curvature, unlike a bifocal lens, which is sharply divided. For this reason, progressive lenses are also known as no-line lenses. This makes for not just clearer vision at all distances, but also good transitions in between.

But, you may need some time to adjust to no-line lenses. Despite the fact that the gentle lens curve results in a product that is elegant, the lens's areas of focus are relatively small, so that there's also room for transitional areas.

Even though multifocal lenses (sometimes called trifocals) are for presbyopia, bifocals are often used to aid children or adolescents with issues such as eye teaming, or being unable to focus while reading, which causes headaches.

Although it may seem like an easy fix, 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 an incorrect prescription can make you susceptible to headaches, eye strain or even nausea. Presbyopia catches up to most of us by a certain age, but there are ways to make it less debilitating. A simple pair of multifocals will make a world of difference.
