Are you over 40 and finding it more of a challenge to read small print? You might be developing presbyopia, a condition that affects many of those who are approaching their 40s. But having presbyopia when you already need glasses for distance vision doesn’t mean you need to start switching between two pairs of specs. Multifocal lenses, which correct both myopia and presbyopia, allow you to see clearly at all times, with one pair of glasses.
Multifocals are much better than bifocals. Bifocals corrected problems with both near and far vision, but usually objects in between were blurry. To rectify this problem, progressive lenses were developed. These give you and intermediate or transition part of the lens that allows your eyes to focus on the area between things like the newspaper and far objects like road signs. But what creates this effect? Well, progressive lenses are specially curved, unlike a bifocal lens, which is sharply sectioned. For this reason, progressive lenses are also called no-line lenses.
But, you may need a bit of time to get used to no-line lenses. While the subtle transition of progressive lenses is more aesthetically pleasing, the lens’s areas of focus are relatively small, because they all need to fit.
Bifocals aren’t entirely dated though; they are helpful for kids and teenagers who have a hard time focusing when reading.
Although it may seem like a quick 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.
Glasses that aren’t properly customized to you can lead to eye strain, discomfort and nausea. Presbyopia affects the majority of us by middle age, but there are ways to make it less inconvenient. A good pair of multifocals will ensure that your quality of life isn’t affected.
