As we age, our eyesight often begins to deteriorate. One condition that many individuals over the age of 40 experience is presbyopia, which is caused by the increasing rigidity of the lens in the eye. To correct for this farsightedness, many people turn to bifocals or progressives lenses. In this blog post, we’ll provide an overview of these two common types of vision correction and how they differ from each other.
What is Presbyopia?
Presbyopia is a condition that affects older individuals—usually those over the age of 40—in which they have difficulty focusing on close objects due to the increasing rigidity of their lens within their eye. This often requires vision correction in order to restore clear vision within both near and distant objects.
What are Bifocals?
Bifocals are fairly self-explanatory; they consist of two different corrective lenses within one frame. One area corrects for nearsightedness while the other area corrects for farsightedness or presbyopia. The advantage of bifocal glasses is that you can switch between near and far vision without having to take them off or adjust them—you simply look up or down depending on what you need to focus on. However, bifocals can be bulky and difficult for some people to get used to wearing due to the visible line that separates where each corrective lens starts and ends which can cause a “jump” when looking up or down with your eyes.
What Are Progressive Lenses?
Anyone who feels that the drawbacks of bifocals outweigh the benefits might do better with progressive lenses instead. Unlike bifocals which have a distinct line separating where each corrective lens starts and ends, progressive lenses have no visible line because they use a gradual, seamless transition between near and far vision areas. This allows you to easily transition between distance viewing and reading without having any interruption in your field of view like with bifocal glasses. With every new lens prescription comes an adjustment period, particularly for your first pair of progressive lenses as you learn how best to use them efficiently without getting headaches or dizziness due to their more complex design than traditional bifocal lenses. However once you get used to wearing them you’ll find that progressive lenses offer greater comfort with less eye strain than traditional bifocal glasses do!
Whether you suffer from presbyopia or just want help fine-tuning your vision as you age, there are several options available for correcting your sight including traditional bifocals as well as progressive lenses which offer greater comfort while still providing excellent coverage when it comes time to read text at close range or look out into the distance clearly without needing adjustment! Ultimately it’s up to you decide what type of vision correction will work best for your lifestyle but either way it’s important to make sure that you receive proper eye care from a qualified doctor before making any long-term changes so that your eyes stay healthy!
