Are Bifocal Contacts For You?

By Dr. Eric Stamper, O.D.

First off, if you're under the age of 40 you can stop reading now. BiFocals are not for you. starting at age 40, many require assistance in seeing things up close. Yes, that means you.

Bifocal contact lenses are not for everyone, but they are an exciting option for many. If you're wearing reading glasses, BiFocals, struggling to read the newspaper, or even this article BiFocal contact lenses may be a great option for you.

First, but make us play two very important details. Will we discussed bifocal contact lens fittings, I'm not only referring to troop bifocal contact lenses, but also monovision lenses ( one lens for distance only in one lens for near only), in any conceivable combination of bifocal and monovision lenses. So, I'm really only talking about soft contact lenses.

Here are a few things that would make you a good candidate for bifocal contact lenses, though keep in mind not a single one of these is an absolute requirement: a strong desire to not wear glasses, a willingness to accept vision that isn't quite perfect in exchange for adequate vision at all distances, being closer to age 40 than to age 60, prior contact lens experience, long-time glasses use, and an understanding that reading glasses may still be needed from time to time for small print or poor lighting conditions.

And now a few things that make you a worse candidate: intense fear of touching your eye, high amounts of astigmatism, need for crystal clear vision (perfectionists and Type A folks), very dry eyes, having an eye that doesn't see very well even with the best correction.

There are a couple of things every person should understand prior to trying on any type of bifocal contact lens. 1) Your vision cannot be as clear with bifocal contact lenses as it could be with bifocal glasses, and 2) every person experiences bifocal contact lenses differently and therefore it may take several fittings with vastly different lens combinations before finding the lenses that work best for you.

Bifocal glasses do not work the same as bifocal contact lenses. for soft contact lenses, you cannot look through just one part of the lens at a time. Part of your vision is always focused up closeand part of your vision is always focused at a distance. When you are looking up close your brain learns to concentrate on the part of your vision that is focused up close and block out the part that is focused at a distance, and vice versa when you look at a distance. bifocal contact lenses can not be as perfect as bifocal glasses because part of your vision is always focused at the wrong location. because the brain interprets what we see through bifocal contacts each person has a different experience with bifocal contacts, therefore each fitting is a unique experience.

In my opinion the biggest factor of whether someone will successfully be fit with bifocal contact lenses is the doctor who fits them. Bifocal contact lenses require a firm understanding of how the different lenses work, a doctor must know what changes to make based on each patient's responses to the lenses, the doctor must him- or herself be very patient, and the doctor must set appropriate expectations through proper education. Fitting bifocal contact lenses properly is a challenge.,
