Are you having trouble reading small print? If you're close to middle-age, you might have presbyopia. If you already wear glasses for distance vision, and are later on diagnosed with presbyopia, you don't have to start carrying and switching between two pairs of glasses. Multifocal lenses help you see clearly always, tending to both issues at once.
Multifocals are much better than bifocals. Bifocals corrected poor near and far vision, but often objects in between were blurry. To create something better, progressive lenses were invented, which offer a transition part of the lens that allows you focus on everything between things like the newspaper and street signs. Let's explain how this works. Progressive lenses are expertly curved, unlike a bifocal lens, which is harshly divided. Because of this, progressive lenses are also known as no-line lenses. This creates not only clearer vision at all distances, but also good transitions in between.
Progressive lenses, although better, can require a small period of time to adjust to. Despite the fact that the subtle transition of progressive lenses is more elegant, the focal areas are quite small because the transitional areas also inhabit room.
Even though these progressive lenses (sometimes called trifocals) are for presbyopia, bifocals are still used to treat school-aged children and teens who suffer from issues such as eye teaming, or being unable to focus while reading, which in turn, can lead to headaches.
When being fitted for multifocal lenses, it's important that you're treated by an eye care professional you trust. Multifocal lenses are most beneficial when properly fitted to your unique eyes, needs and line of vision.
Having a wrong prescription can make you susceptible to headaches, eye strain or even nausea. Presbyopia affects the majority of us by a certain age, but there are ways to make it less debilitating. A simple pair of multifocals will make a world of difference.
