Focusing on Multifocal Lenses

Are you experiencing trouble when reading fine 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 need to carry a separate pair of reading glasses. This is because of multifocal lenses, which correct both problems, making sure you always see clearly.

Multifocals are much better than bifocals. Bifocals corrected poor near and far vision, but usually objects in between were blurry. In an effort to create something better, progressive lenses were made, which give you a transition part of the lens allowing your eyes to focus on distances that are in the middle. How does this work? Well, progressive lenses feature a subtle curvature, unlike a bifocal lens, which is harshly divided. Because of this, progressive lenses are also known as no-line lenses. This provides not just clearer vision at all distances, but also nice, easy transitions between the two.

Progressive lenses can take some time to get used to. While the invisible transition of progressive lenses is more aesthetically pleasing, the focal areas are quite small because more lens space is used for the transitional areas.

Even though multifocal lenses (sometimes called trifocals) are for presbyopia, bifocals are still used to aid school-aged children and teens with issues like eye teaming, or being unable to focus while reading, which in turn, can lead to headaches.

Even though it may seem like a quick fix, avoid purchasing pharmacy bifocals. Most 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.

Being fitted with a wrong prescription can leave you with headaches, eye strain or even nausea. During middle age, most people cannot avoid presbyopia. But it's good to know that good, multifocal lenses can make all the difference.
