If you're middled-aged and beginning to notice difficulty reading fine print, you may have presbyopia, a common age-related condition that makes it difficult to focus on close objects. If you already struggle with 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 have good vision all the time, correcting your presbyopia and myopia with just one pair of glasses.
Multifocals are much better than bifocals. Bifocals did correct poor near and far vision, but left middle vision a little blurred. To create something more helpful, progressive lenses were made, which give you and intermediate or transition part of the lens which lets you focus on distances that are somewhere in the middle. But what creates this effect? Well, progressive lenses are specially curved, unlike a bifocal lens, which is harshly sectioned. Because of this, progressive lenses are also known as no-line lenses. This makes for not only clearer vision at near and far distances, but also good transitions in between.
These lenses may require a small period of time to get used to. Even though the invisible lens curve results in a product that is aesthetically pleasing, the focal areas are relatively small because the transitional areas also take up room.
Bifocals still have their uses though; they are used to treat children and teens who experience eye strain, which is the result of a difficulty focusing while reading.
When the time comes to get fitted for multifocal lenses, make sure it's with an eye care professional you feel comfortable with. Multifocal lenses are most beneficial when properly fitted to your eyes, needs and line of vision.
If you've been fitted with the wrong prescription you could end up suffering from headaches, eye strain or even nausea. During middle age, most of us will not be able to avoid presbyopia. But it's important to know that good, multifocal lenses can make all the difference.
