Bifocal Contact LensesIt's one of the sad facts of life. One of the effects of aging is the gradual decline of your ability to focus on objects held at arm's length or closer. The medical term for the condition is 'presbyopia', and it tends to happen to most of us as we near middle age. If you're starting to find yourself holding the newspaper out at arm's length, or putting the book down on the table in order to see it, bifocal contact lenses may be the solution to your problem. Types of bifocal contact lensesLike bifocal spectacles, bifocal contact lenses combine both a prescription for nearsightedness and one for farsightedness in one lens. There are several different kinds of bifocal contact lenses that combine the separate prescriptions in different ways. All of them are soft contact lenses, designed to float on the surface of the eye, and will be customized for your prescription. Your eye care professional can help decide which type is the right one for you out of the different designs of bifocal contact lenses listed below. Translating bifocal contact lenses
Translating bifocal contact lenses have the near and far prescriptions in distinctly separated
areas, much like regular bifocal eyeglasses. This generally means that the prescription to correct
your near vision is at the bottom, and far vision is at the top, but occasionally the prescriptions
may be reversed. In addition, if there's a need for an "intermediate" prescription, the lenses may
contain all three corrective prescriptions in three separate areas. The eye will learn to focus
through the appropriate area of the lens just as people who wear bifocal spectacles learn to focus
their gaze through the top of the lenses when looking at things in the distance and through the
bottom when reading. Annular or concentric bifocal contact lens
There are two bifocal designs that work much better for those with small pupils, or whose need for
near vision correction is relatively small. Both 'blend' the corrective prescriptions in different
ways. 'Aspherical' lens
The second type of multi-focal contact lens is the 'aspherical' lens. The prescription areas are
both placed near to the center of the eye, at or just above the pupil. In use, it is the most
like 'natural' vision, where your eyes learn to ignore far objects while focusing on things that
are close, and the reverse when focusing on objects that are further away. Monovision fit and hybrid bifocal fit
Two other options that deserve consideration when you're thinking about getting bifocal contact
lenses are a monovision fit and a hybrid bifocal fit. In a monovision fit, one eye is fitted
with the prescription for near vision, and the other with the prescriptions for far vision.
Your eyes will adjust to using the correct eye for the correct task, though it may take a while
for you to get used to it. With hybrid bifocals, one eye is fitted with a bifocal contact lens
and the other is fitted with a prescription for the stronger need. Like monovision, your eyes
will adjust to using the eye with the proper correction for the task. Where can you find cheap bifocal contact lenses?ACUVUE BIFOCAL contact lenses is the most popular doctor-prescribed brand of bifocal contact lenses.
