Are Bifocal Contacts For You?

By Dr. Eric Stamper, O.D.

While this article is not for everyone, let me first explain who it is for. If you are over the age of 40, please read on. every one, at some time in their life will require assistance reading up close.

If you are wearing reading glasses, bifocals, or struggling to read this article, bifocal contact lenses are a great option, but are not for everyone.

First let's start off by qualifying a few details of the article. In the article, I am only talking about soft contact lenses. Next, when I refer to BiFocal contact lens fittings, this will only refer totrue bifocal contact lenses ( as seen on TV), this also shall refer to monovision ( one lens for distance and one lens for near), and every possible combination.

Here are a few things that would make you a good candidate for bifocal contact lenses: an understanding that reading glasses may still be required from time to time for small print orpoor lighting conditions, longtime glasses use, prior contact lens experience, being closer to age 40 than age 60, being willing to accept vision that isn't quiteperfect in exchange foradequate vision at all distances, and a strong desire not to wear glasses.

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.

Choosing the right doctor is important with bifocal contact lenses. The doctor must have a firm understanding of how the lenses work, the doctor must be very patient, the doctor must know what changes to make based upon each patient's response to the lenses, and must set appropriate expectationswith proper education. Not all doctors are willing to accept the challenge with bifocal contact lenses, so choose wisely.

Contact a local eye doctor for your specific requirements with bifocal contact lenses and to see if bifocal contact lenses are right for you. - 16463
