Many people develop problems with reading small print and seeing close objects during their 40s. This is known as presbyopia. If you already struggle with distance vision, and develop presbyopia, you don’t have to carry a separate pair of reading glasses. Multifocal lenses will allow you to see clearly all the time, correcting your presbyopia and myopia with just one pair of glasses.
In the past, bifocals were widely prescribed, but they weren’t perfect; while they correct problems with both near and distant objects, everything else is blurred. To fix this problem, progressive lenses were made. These give you and intermediate or transition part of the lens which lets your eyes to focus on distances that are in the middle. Let’s explain how this works. Well, progressive lenses are specially curved, unlike a bifocal lens, which is harshly sectioned. For this reason, progressive lenses are also called no-line lenses.
These lenses can take some time to get used to. While the invisible transition of progressive lenses is more elegant, the lens’s areas of focus are relatively small, because they all need to fit.
Even though these progressive lenses (or trifocals) are for presbyopia, bifocals are still used to treat children or adolescents with eye problems like eye teaming, or being unable to focus properly, which in turn, can lead to eye strain.
When the time comes to get fitted for multifocal lenses, make sure it’s with an eye care professional you feel comfortable with. Multifocal lenses are most beneficial when properly fitted to your unique eyes, prescription and line of vision.
If your prescription or fit is off you may find yourself suffering from eye strain, discomfort and nausea. At a certain age, most people will not be able to avoid presbyopia. But it’s important to know that good, multifocal lenses can make all the difference.
