Bettering the Bifocal: Multifocal Lenses

If you're close to the age of 40 and beginning to observe some difficulty reading fine print, you may have presbyopia, a common age-related condition that prevents you from clearly seeing close objects. But developing presbyopia when you already wear glasses for distance vision doesn't mean you now need two pairs of glasses. Multifocal lenses, which rectify both myopia and presbyopia, let you see clearly at all distances with one pair of glasses.

In the past, bifocals were the obvious solution, but they have a major flaw; while they correct problems with both near and distant objects, middle distance is blurred. To create something more helpful, progressive lenses were invented. These give you a transition region which lets your eyes to focus on everything between things like the books you read and far objects like road signs. Progressive lenses, which are also called no-line lenses, are a type of multifocal lens that have a subtle curvature across the lens, rather than a noticeable line separating the two parts of the lens.

However, you might take some time to adjust to no-line lenses. Despite the fact that the subtle lens curve is more elegant, the focal areas are relatively small because the transitional areas also inhabit room.

While these days, multifocal lenses (sometimes called trifocals) are for presbyopia, bifocals are often employed to aid children or adolescents with eye problems such as eye teaming, or being unable to focus while reading, which causes headaches.

When being fitted for multifocal lenses, make sure it's with an eye care professional you trust. Multifocal lenses are most beneficial when they're customized to your eyes, prescription and line of vision.

Having a wrong prescription can make you susceptible to eye strain, discomfort and even migraines. During middle age, most of us will not be able to avoid presbyopia. But it's comforting to know that good, multifocal lenses can make it a lot easier.
