Bettering the Bifocal: Multifocal Lenses

Are you having trouble reading small print? If you're close to middle-age, you might have presbyopia. But, this doesn't mean that people who already have prescription eyeglasses for distance vision need to carry around two pairs of glasses and continually change them. Multifocal lenses will allow you to see clearly always, correcting your presbyopia and myopia with just one pair of glasses.

Before mulifocals, bifocals were the obvious solution, but they have a significant shortcoming; while they correct problems with both near and distant objects, middle distance is blurred. In an effort to create something more helpful, progressive lenses were made. These offer a transition region allowing your eyes to focus on distances that are in the middle. Progressive lenses, which are also known as no-line lenses, are a type of multifocal lens featuring a gently curved lens, rather than a sharp line distinguishing both areas of the lens. This makes for not just better vision at all distances, but also good transitions in between.

However, it can take some time to get used to these lenses. Even though the invisible lens curve is more aesthetically pleasing, the focal areas are quite small because the transitional areas also take up room.

Even though these progressive lenses (sometimes called trifocals) are for presbyopia, bifocals are still employed to treat children or adolescents who have other eye problems such as eye teaming, or being unable to focus properly, which in turn, can lead to eye strain.

Multifocal lenses work best when they're made to work with your specific requirements. When you're ready to get yours, make a point to work with a professional you feel comfortable with.

A badly fitted pair of glasses can lead to headaches, eye strain or even nausea. At a certain age, most of us will not be able to avoid presbyopia. But it's important to know that good, multifocal lenses can make all the difference.
