Are you having difficulty when reading fine print? If you're close to middle-age, you might have presbyopia. It's comforting to know that having presbyopia when you already wear glasses for distance vision doesn't mean you need to start switching between multiple pairs of specs. Multifocal lenses will allow you to see clearly all the time, correcting your presbyopia and myopia with just one pair of glasses.
At one point, bifocals were the popular fix, but they have a significant flaw; even though they correct problems with both near and distant objects, everything in between is blurred. To correct this problem, progressive lenses were invented, which give you and intermediate or transition part of the lens that allows your eyes to focus on distances that are in the middle. Let's explain how this works. Progressive lenses are expertly curved, unlike a bifocal lens, which is sharply divided. Because of this, progressive lenses are also called no-line lenses.
These lenses can require some time to get used to. Despite the fact that the subtle lens curve results in a product that is aesthetically pleasing, the focal areas are quite small because the transitional areas also inhabit space.
While these days, these progressive lenses (or trifocals) are for presbyopia, bifocals are still employed to aid young patients who suffer from eye problems like eye teaming, or being unable to focus while reading, which causes eye strain.
Although it may seem like a quick fix, it's best to steer clear of drug store bifocals. Most of these types of glasses are one-size-fits-all, which means that the both lenses contain the same prescription and are not customized for the wearer.
A badly fitted pair of glasses can lead to eye strain, discomfort and nausea. Presbyopia catches up to the majority of us at a certain age, but there are ways to make it less inconvenient. A good pair of multifocals will make a world of difference.
