If you are around the age of 40 and starting to observe some difficulty reading fine print, you might have developed presbyopia, a common age-related condition that makes it difficult to focus on close objects. It’s comforting to know that developing presbyopia when you already wear glasses for near sightedness doesn’t mean you need to start switching between multiple pairs of specs. Multifocal lenses, which rectify both myopia and presbyopia, help you see well at all distances with one pair of glasses.
Multifocals are much better than bifocals. Bifocals do fix poor near and far vision, but left everything in between a little blurred. To fix this issue, progressive lenses were developed, which give you a transition region allowing your eyes to focus on the area between near and far distances. How does this work? Progressive lenses are specially curved, unlike a bifocal lens, which is sharply divided. Because of this, progressive lenses are also called no-line lenses.
However, you may require some time to adjust to no-line lenses. Even though the invisible lens curve is more elegant, the lens’s areas of focus are small, so they they’re all able to fit.
Even though these progressive lenses (or trifocals) are for presbyopia, bifocals are still used to treat school-aged children and teens who have other issues like eye teaming, or being unable to focus properly, which in turn, can lead to headaches.
Multifocal lenses work best when they’re customized to your exact and unique needs. So when it’s time to get fitted, make sure it’s with a professional you can trust.
Having a wrong prescription can leave you with headaches, eye strain or even nausea. During middle age, most people cannot dodge presbyopia. But it’s comforting to know that the right lenses can make all the difference.
