If you're middled-aged and beginning to notice difficulty reading small print, you might have presbyopia, a common age-related condition that prevents you from clearly seeing close objects. But, this doesn't mean that those who already wear glasses to tend to their problems with nearsightedness need to carry around two pairs of glasses and continually switch between them. This is because of multifocal lenses, which help you with both problems, making sure you always see clearly.
At one point, bifocals were widely prescribed, but they have a significant disadvantage; while they correct problems with both near and distant objects, everything in between is blurred. In an effort to create something better, progressive lenses were invented. These offer and intermediate or transition part of the lens allowing you focus on the area between near and far distances. Let's explain how this works. Well, progressive lenses are expertly curved, unlike a bifocal lens, which is sharply sectioned. For this reason, progressive lenses are also called no-line lenses.
But, you might require some time to adjust to these lenses. Despite the fact that the subtle lens curve results in a product that is elegant, the focal areas are quite small because the transitional areas also take up space.
While these days, multifocal lenses (also called trifocals) are for presbyopia, bifocals are still used to aid children or adolescents with issues such as eye teaming, or being unable to focus while reading, which causes headaches.
Multifocal lenses are most helpful when they're made to work with your exact and unique needs. When you're ready to get yours, enlist the services of a professional you can trust.
A badly fitted pair of glasses can lead to headaches, eye strain or even nausea. Presbyopia affects most of us by a certain age, but there are ways to make it less restricting. A good pair of multifocals can ensure that your quality of life isn't affected.
