If you’re close to 40 and having some trouble reading fine print, you might have developed presbyopia, a common age-related condition that makes it harder to focus on close objects. Fortunately, this doesn’t mean that people who already have prescription eyeglasses to tend to their problems with nearsightedness need to own two pairs of glasses and constantly change them. Multifocal lenses will allow you to have good vision always, tending to your presbyopia and myopia at once.
Multifocals are far superior to bifocals. Bifocals corrected problems with both near and far vision, but often objects in between were blurry. To fix this issue, progressive lenses were developed, which provide wearers with and intermediate or transition region that allows you focus on distances that are in the middle. Progressive lenses, which are also known as no-line lenses, are a type of multifocal lens that have a subtly curved lens, instead of an obvious and harsh line distinguishing the two parts of the lens.
However, you may take a bit of time to adjust to no-line lenses. Even though the gentle transition of progressive lenses is more elegant, the focal areas are quite small because more lens space is used for the transitional areas.
While these days, multifocal lenses (sometimes called trifocals) are for presbyopia, bifocals are still employed to treat children or adolescents with eye problems like eye teaming, or being unable to focus while reading, which causes eye strain.
It’s also important to get fitted properly, and not turn to drugstore bifocals. A lot of these types of glasses are one-size-fits-all, which means that the both lenses contain the same prescription and are not customized for the wearer.
If you’ve been fitted with an incorrect prescription you could find yourself suffering from eye strain, discomfort and headaches. During middle age, most of us cannot dodge presbyopia. But it’s important to know that good, multifocal lenses can make it a lot easier.
