Multifocal Lenses and You

Are you over 40 and struggling to read small print? You might be developing presbyopia, a condition that affects many of those reaching their 40s. But, this doesn't mean that individuals who already have glasses to tend to their problems with distance vision need to carry around two pairs of glasses. Multifocal lenses, which correct both myopia and presbyopia, help you see well at all distances with one pair of glasses.

At one point, bifocals were widely prescribed, but they have a major shortcoming; even though they correct problems with both near and distant objects, everything else is blurred. To create something more helpful, progressive lenses were made. These offer and intermediate or transition region allowing your eyes to focus on the area between near and far distances. How does this work? Well, progressive lenses feature a subtle curvature, unlike a bifocal lens, which is sharply divided. For this reason, progressive lenses are also known as no-line lenses. This provides not just clearer vision at all distances, but also smooth, easy transitions in between.

Progressive lenses, although better, can take some time to get used to. 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.

While these days, these progressive lenses (also called trifocals) are for presbyopia, bifocals are still employed to treat young patients who have other issues like eye teaming, or being unable to focus properly, which causes headaches.

It's also crucial to get professionally fitted, and not turn to drugstore bifocals. Many of these types of glasses have the same prescription in both lenses, which will not help a lot of people.

A badly fitted pair of glasses can lead to headaches, eye strain or even nausea. Presbyopia catches up to the majority of us by middle age, but it doesn't have to be restricting. A good pair of multifocals will make a world of difference.
