If you're middled-aged and having some difficulty reading fine print, you may have developed presbyopia, a common age-related condition that makes it harder to focus on close objects. Fortunately, this doesn't mean that people who already have prescription eyeglasses for nearsightedness are required to carry around two pairs of glasses. This is because of multifocal lenses, which can take care of both problems, making sure you always see clearly.
At one point, bifocals were the popular fix, but they were far from perfect; even though they correct problems with both near and distant objects, middle distance is blurred. In an effort to create something better, progressive lenses were developed, which give you and intermediate or transition part of the lens allowing you 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 subtly curved lens surface rather than an obvious and harsh line dividing the two parts of the lens.
However, you may require some time to get used to these lenses. Despite the fact that the gentle lens curve results in a product that is aesthetically pleasing, the focal areas are relatively small because the transitional areas also inhabit space.
Bifocals still have their uses though; they are helpful for children and teenagers who have a hard time focusing when reading.
When being fitted for multifocal lenses, it's crucial that you're treated by an eye care professional you feel comfortable with. Multifocal lenses are most beneficial when they're customized to your eyes, prescription and line of vision.
If your prescription or fit is off you could end up suffering from headaches, eye strain or even nausea. During middle age, most people cannot dodge presbyopia. But it's important to know that the right lenses can make all the difference.
