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.

A bifocal contact lens has two divisions. There is a line like you would find on your classes towards the bottom of the contact lens and another line towards the top. This helps your eye focus on the picture in front of you.

Bifocal lenses also come in different designs to accommodate people with different eye problems. With the perfect design, the eyes can adjust the distance and adjust the vision.

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.
