Considering Bifocal Contacts

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.

Though not a requirement, these are a few things that may make you a great candidate for bifocal contact lenses: A strong desire to stop wearing glasses, being closer to age 40 than age 60, prior experience with contact lenses, longtime glasses use, a willingness to accept vision that isn't quite perfect in exchange for adequate vision at all distances, and you must understand that reading glasses may still be required from time to time for small print or in poor lighting conditions.

Signs you might not be the best candidate: very dry eyes, having an eye that doesn't seem very well even with the best correction, an intense fear of touching your eyes, high amounts of astigmatism, and the need for crystal clear vision.

Because every person experiences bifocal contact lenses differently, it may take several fittings with vastly different lens combinations before finding the lenses that work best for you. your vision cannot be as clear with bifocal contact lenses as it would with bifocal glasses. Anyone considering bifocal contact lenses should understand this prior to trying on any type of bifocal contact lens.

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.

So what is the biggest factor in deciding whether someone will be successfully fit with bifocal contact lenses? Choosing the right doctor is a major factor. You want a doctor that understands how the different lenses work, a doctor must know what changes to make based upon your input, they must be patient, and should set the right expectations through educating you. While this can be a challenge, it's not impossible with the right doctor.

To find out if you would be a good candidate for bifocal contact lenses, contact your local eye doctor for a complete evaluation and to learn more about bifocal contact lenses.
