Progressives and Bifocals Lenses
If you are over 40 and having difficulty with your vision close up, chances are you are experiencing presbyopia. It’s a gradual change in the ability to focus, and a condition that effects almost everyone as they age. But there is good news: you have more choices today than ever before to correct it.
Progressive addition lenses, or “no-line bifocals,” offer a gradual transition from distance to near vision, while also allowing you to see objects at arm’s length. This means that instead of having only two different viewing zones (near and distant), like with bifocals, progressive lenses provide vision at all distances and provide more natural vision correction.
Bifocal lenses have a very distinct line dividing a reading area from distant viewing. They are designed to allow you to see objects either near or far by essentially combining two lenses into one. However, this older bifocal technology has been replaced by more desirable and attractive progressive lens technology.
