If you're middled-aged and having some difficulty reading books and newspapers, you may have developed presbyopia, a common age-related condition that makes it challenging to focus on close objects. But, this doesn't mean that individuals who already wear prescription eyeglasses for distance vision need to own two pairs of glasses and constantly change them. This is all thanks to multifocal lenses, which help you with both problems, making sure you always see well.
In the past, bifocals were the popular fix, but they weren't all that great; even though they correct problems with both near and distant objects, everything in between is blurred. In an effort to create something more helpful, progressive lenses were made. These give you a transition region which lets your eyes to focus on distances that are in the middle. Progressive lenses, which are also known as no-line lenses, are a type of multifocal lens featuring a gently curved lens, rather than an obvious and harsh line distinguishing both parts of the lens.
But, you might take some time to adjust to no-line lenses. While the invisible transition of progressive lenses is more aesthetically pleasing, the focal areas are quite small because the transitional areas also take up room.
Bifocals still have their uses though; they are helpful for kids and teenagers who experience eye strain, which is the result of a struggle to focus while reading.
When being fitted for multifocal lenses, check that it's with an eye care professional you feel comfortable with. Multifocal lenses work best when they're customized to your unique eyes, prescription and line of vision.
If you've been fitted with the wrong prescription you may find yourself suffering from headaches, eye strain or even nausea. During middle age, most of us cannot dodge presbyopia. But it's important to know that good, multifocal lenses can make it a lot easier.
