Bettering the Bifocal: Multifocal Lenses

Presbyopia, or far-sightedness, is a common condition that often begins to affect those who are 40 or older. It’s comforting to know that having presbyopia when you already need glasses for near sightedness doesn’t mean you need to start switching between multiple pairs of specs. This is because of multifocal lenses, which correct both problems, ensuring that you always see well.

Multifocals are much better than bifocals. Bifocals did correct poor near and far vision, but often objects in between were blurry. In an effort to create a better product, progressive lenses were developed. These offer and intermediate or transition part of the lens that allows your eyes to focus on distances that are in the middle. Progressive lenses, which are also called no-line lenses, are a type of multifocal lens made with a subtly curved lens, rather than a noticeable line distinguishing the two parts of the lens. This provides not only better vision at near and far distances, but also good transitions in between.

But, it can take some time to get used to no-line lenses. While the subtle lens curve results in a product that is aesthetically pleasing, the lens’s areas of focus are relatively small, so that there’s also room for transitional areas.

Bifocals aren’t entirely dated though; they are used to treat children and teenagers who have a hard time focusing when reading.

Even though it may appear to be an easy solution, avoid buying drug store bifocals. Most of these “ready-made” glasses are one-size-fits-all, which means that the both lenses contain the same prescription and that the optical center of the lens is not customized for the wearer.

A badly fitted pair of glasses can lead to eye strain, discomfort and nausea. Unfortunately, presbyopia is just a part of getting older. But keep in mind that multifocal lenses can make all the difference.
