Are you older than 40 and your vision isn’t as good as it used to be? Don’t worry this happens to the best of us. As we age our eyes change, inevitably developing a new error known as presbyopia. Presbyopia is an error in vision that limits our ability to see things up close. A sign that you have developed this is if you’ve been needing to hold your book at arm’s length or increase the text size on your phone. A trip to your local Paducah, KY Optometrist can help you confirm your suspicion and help get you started with multifocal lenses, which will help correct the issue.
What Type of Multifocal Lenses are There?
Progressive Lenses: Progressive lenses are different than other types of lenses. They offer a gradual change in power from the top section of the lens to the bottom. This creates a smoother progression from one type of correction to the next. They are also both thinner and lighter than other types of multifocal lenses.
Trifocal Lenses: Trifocal lenses solve three different refractive errors at once. In this type of multifocal lens, there are multiple parts. The middle portion of this lens offers correction for your immediate vision, which is helpful for working at your computer. It’s further away from reading a book, but also still closer than seeing a sign while driving.
Bifocal Lenses: Having issues seeing things far away, and things up close? If so, you may need to get bifocal lenses to help out your problem. These types of lenses help correct your vision issue as they function as both reading glasses and normal eyeglasses. This is due to the top half of the lens containing your distance vision prescription. The bottom half of the lens, on the other hand, contains your near-vision correction.
What Should I Expect When Wearing Multifocal Lenses?
Vision
You may need to help train your eyes on where to look to see different distances correctly. An example of this would be walking downstairs. Usually, when we have normal vision or just prescription lenses, we look downward when walking downstairs. However, if you are wearing bifocals it may be difficult as the bottom part of the lens magnifies, helping you see up close.
You may need also to change how you hold your reading material or how you gave through the magnified section of progressive or bifocal lenses.
On occasion, people have reported experiencing some dizziness or nausea with the different levels in their progressive lenses. These side effects however tend to go away after a few weeks of consistently wearing your glasses.
Adjustment Period
On average it takes around two weeks to properly adjust to the blended corrective strengths of your new glasses. Wearing your glasses on a constant basis can help you adjust faster. If you continue to have trouble after two weeks, go see your local Paducah, KY Optometrist. They will make sure your lenses are the right choice for you.
Fit
Depending on which type of multifocal lenses were prescribed to you, they may fit quite differently than prior glasses. Precise measurements are used to make a big difference in whether you can see things clearly. An example of this would be bifocal lenses. They are typically placed so that the corrective line is in the same place as your lower eyelid. Trifocals can also be placed higher, so they line up with the lower margin of your pupil. These can help wearers have a clear line of sight to things in both their distant and immediate view.
