Progressive and Multifocal Lenses

Are you over 40 and struggling to read small print? You might have presbyopia, a common condition affecting those who are approaching middle age. But developing presbyopia when you already need glasses for distance vision doesn't mean you need to start switching between multiple pairs of glasses. This is all thanks to multifocal lenses, which correct both problems, ensuring that you always see clearly.

Before mulifocals, bifocals were widely prescribed, but they have a major flaw; even though they correct problems with both near and distant objects, middle distance is blurred. In an effort to fix this issue, progressive lenses were developed, which provide wearers with a transition part of the lens that allows your eyes to focus on everything between things like the newspaper and far objects like road signs. But what creates this effect? Progressive lenses feature a gradual curvature, unlike a bifocal lens, which is sharply divided. Because of this, progressive lenses are also called no-line lenses. This provides not only better vision at all distances, but also smooth, easy transitions in between.

These lenses, although better, can take a small period of time to adjust to. While the subtle 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.

While these days, these progressive lenses (or trifocals) are for presbyopia, bifocals are often used to help children or adolescents with eye problems like eye teaming, or being unable to focus while reading, which causes eye strain.

When the time comes to get fitted for multifocal lenses, it's important that you're attended to by an eye care professional you trust. Multifocal lenses work best when they're customized to your unique eyes, needs and line of vision.

Glasses that aren't properly customized to you can lead to headaches, eye strain or even nausea. During middle age, most of us will not be able to dodge presbyopia. But it's important to know that good, multifocal lenses can make it a lot easier.
