Bifocal Contact Lenses

Bifocal Contact Lenses Patients with presbyopia (patients who experience blurry vision as a result of not being able to focus at all distances) can now use bifocal contact lenses to treat their condition. Key signs and symptoms of presbyopia include needing to hold reading material farther and farther from the eyes in to see clearly.

Previously patients with this condition were limited to bifocal prescription glasses. Bifocal lenses however are now available in both soft and rigid materials. Many patients are now enjoying the added convenience of buying disposable bifocal contact lenses.

Bifocal Contact User Guide
How do bifocal lenses work? Much like eyeglasses, bifocal contact lenses help correct distance and near vision. A single lens typically includes two separate prescriptions. The top prescription works to correct distance vision whereas the bottom of the lens includes a prescription to treat near vision.

Some bifocal lenses work by combining different prescriptive powers that is blended onto various parts of the lens. The wearer's eye will slowly adjust to differentiate the appropriate power needed to correct vision when viewing something at near or distant visions.

Are You A Candidate for Bifocal Lenses?
Not everyone is a good candidate for bifocal contact lenses. Typically it takes the eye some time to adjust the varying prescriptive powers of these lenses. Some people will find it takes too long to adjust to the lenses. Others will have needs that exceed the ability of bifocal contact lenses.

Fortunately for people bifocal contacts are not suitable for, there are alternatives available. Your eye care professional may for example prescribe monovision contact lenses. This will require you wear a single contact lens to correct distance vision in one eye and another contact lens to correct near vision in the other eye. Each of us tends to have a dominant eye. Usually the distance correction lens is placed in the dominant eye to help promote better overall vision.

While this seems a bit unusually many people readily adjust to wearing two differing prescription lenses. Most don't even notice that each eye is performing a different function. There are of course disadvantages, including the fact that one eye will work solely to perform near vs. distance vision tasks. Some people find they more often than not have to adjust their head position frequently to see something correctly. Others note a slight decrease in depth perception.

The good news is if you are interested in exploring one of these options, most doctors will wiling provide a trial program to allow you the benefit of trying out a bifocal contact lens or a monovision contact lens to see if the prescription is something that may work for you. If you are a fan of contact lenses this may be a good alternative to relying solely on eyeglasses for vision support.

Bifocal Eyeglasses
For those that must rely on traditional bifocal eyeglasses, modern technology has afforded wearers many new and fashionable looks. No longer do bifocal wearers have to rely on ugly designs with huge lines spanning the width of the lenses. Many bifocal glasses now provide small half moon lines and some even provide bifocal ability without the visible line down the middle.

If you are a candidate for bifocals your eye care professional will explore all of your vision alternatives with you. Together you can decide whether contact lenses or eyeglasses will better suit your eyes and your personal and style preferences.
