Do you need bifocal lenses?
About the age of 40, nearly all of us develop the symptoms of a condition called presbyopia. You might have difficulty reading text when you try to read a book or when you use your phone. If you already wear prescription lenses, whether glasses or contacts or both, you will need to see your eye doctor for a checkup and a referral to optometry to get bifocal lenses. If you live in or around Naples, FL, we invite you to make an appointment with Naples Eye Physicians.
Bifocal Lenses. One lens, two functions
When you have presbyopia, your eyes don't have the ability to focus so you can see objects close to you clearly. Bifocal lenses contain lenses at two different powers that enable you to see objects clearly both up close and far away. We prescribe bifocal lenses mostly for people who have presbyopia, but sometimes we prescribe them for children and young adults who have focusing problems that cause eye strain. We also sometimes consider bifocals for children who do a lot of reading and close work to prevent nearsightedness.
No matter why you need bifocal lenses, all bifocals work the same way. There is a large, upper portion of the lens ground to give you sharp and clear distance vision. There is a smaller, lower portion of the lens ground to give you sharp and clear vision up close. If the only refractive error we need to correct is presbyopia, the upper portion of the bifocal lens is ordinary glass or plastic. There is also a style of glasses for people who only need corrective lenses for reading called "executive" lenses. These glasses have the full bottom half of bifocal lenses without the part of the lens for distant vision correction. We also prescribe bifocal contacts.
There are people who need bifocal lenses instead of progressive lenses that give you multi-focal correction without lines. Some people just can't get used to progressive lenses. And some people need to have sharp peripheral vision for some sports and some driving situations. They also benefit from bifocal glasses or bifocal contact lenses rather than progressive lenses.
And if cost is a consideration, bifocals are considerably less expensive than progressive lenses.
