Are you over 40 and finding it more of a challenge to read small print? You might have presbyopia, a common condition affecting those who are approaching middle age. But having presbyopia when you already need glasses for near sightedness doesn’t mean you now need two pairs of specs. Multifocal lenses help you see clearly always, correcting your presbyopia and myopia with just one pair of glasses.
At one point, bifocals were the popular fix, but they weren’t all that great; while they help you to focus on both near and distant objects, middle distance is blurred. In an effort to correct this issue, progressive lenses were developed. These give you and intermediate or transition part of the lens allowing you focus on distances that are somewhere in the middle. Progressive or no-line lenses are a type of multifocal lens that have a gently curved lens, instead of a noticeable line separating both areas of the lens.
But, it can take some time to get used to these lenses. Despite the fact that the gentle transition of progressive lenses results in a product that is elegant, the lens’s areas of focus are small, so that there’s also room for transitional areas.
Bifocals still have their uses though; they are used to treat children and teenagers who have a hard time focusing when reading.
Even though it may seem like an easy fix, avoid buying pharmacy bifocals. Many of these types of glasses are one-size-fits-all, which means that the prescription is the same in both lenses and that the optical center of the lens is not customized for the wearer.
Having an incorrect prescription can lead to 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.
