If you're middled-aged and having some difficulty reading books and newspapers, you may have developed presbyopia, a common age-related condition that prevents you from clearly seeing near objects. Fortunately, this doesn't mean that people who already have prescription eyeglasses for nearsightedness need to carry around two pairs of glasses and continually change them. Multifocal lenses help you see clearly always, tending to your presbyopia and myopia at once.
Multifocals are far superior to bifocals. Bifocals do fix problems with both near and far vision, but left middle vision a little blurred. To create something better, progressive lenses were made. These offer and intermediate or transition region that allows you focus on everything between near and far distances. How does this work? Well, progressive lenses feature a subtle curvature, unlike a bifocal lens, which is sharply divided. For this reason, progressive lenses are also called no-line lenses.
These lenses, although better, can require some time to adjust to. Even though the invisible lens curve results in a product that is elegant, the lens's areas of focus are small, so they they're all able to fit.
Bifocals still have their uses though; they are helpful for children and teenagers who suffer from eye strain, which is the result of a difficulty focusing while reading.
When being fitted for multifocal lenses, make sure it's with an eye care professional you trust. Multifocal lenses work best when properly fitted to your unique eyes, needs and line of vision.
A badly fitted pair of glasses can lead to headaches, eye strain or even nausea. Unfortunately, presbyopia is just a part of aging. But keep in mind that multifocal lenses can make all the difference.
