Bifocal Contact Lens

As we age, many of us notice that we can't read as well as we used to. We hold things out further and further, literally at arm's length, until friends and relatives inevitable begin joking about our arm's getting shorter.

The same mechanism is involved in bifocal contact lenses as with bifocal glasses. There are contact lenses available with two different vision options at the top and bottom of the lenses. One advantage with contact lenses is there are lenses where the lens is accommodated with different powers on different parts of the lens.

Until recently, bifocal wearers had few options when choosing corrective eyeware. Glasses with bifocal lenses were the most common option. Luckily, no-line bifocal lenses were developed, and the glasses became somewhat more attractive. Some struggled with the "one contact lens" option, called monovision, but this seemed to result in a lot of squinting for the users and usually required a difficult adjustment period.

Soft and RGP contacts are the two main varieties available for patients suffering from presbyopia. As with the regular wear lenses, they can be disposable or made for long-term usage. The disposable kind is the most popular since the user has the option of using a new pair every day.

Bifocal contact lenses like regular contact lenses are tinted so they are easy to find. The special lines on the contact will help you figure out how to put the contact in your eye. Bifocal contact lenses should only be worn by those who need them, like bifocal glasses. If you haven't reached the age where you would need bifocal contact lenses and your vision is still blurry you might need a new prescription or a correction for an eye problem like an astigmatism.

Aspheric lenses have a more gradual change between focuses. Both of the powers are in the area of the pupil, and as with the concentric lens, the eye will adjust and learn to choose the proper focus to use.
