Invented by Benjamin Franklin, bifocal lenses are designed to help you see objects up close and in the distance.
In this article, I'll review everything you need to know about bifocal lenses to determine if they're the right lens option for you.
What are bifocal lenses?
Separated by a visible line, the top portion of bifocal lenses are for your distance vision while the bottom portion is for your up close vision. This is in contrast to single vision lenses that have one power throughout the lens.
Depending on your vision needs, bifocal lenses can help you see at the following distances:
Up close – as if you’re looking at your cell phone.
In the distance – as if you’re looking at street signs.
Unfortunately, they do not provide clear vision at intermediate distances, such as working on your computer.
What vision conditions do bifocal lenses correct?
Bifocal lenses are designed to correct the following:
Nearsightedness (myopia).
Farsightedness (hyperopia).
Astigmatism.
Presbyopia.
Who is the best candidate for bifocal lenses?
Many people over the age of 40 wear progressives. Progressive lenses are the most versatile lens option that allows them to see clearly at all distances without having to take their glasses on and off.
However, some people over the age of 40 prefer lined bifocals. These lenses are less expensive than progressives and easier to adapt to.
