Bifocal Contact Lenses
February 10, 2010 - Rodney Smith
Usually in our 40's there is a need for bifocals or reading glasses. And sometimes patients believe that they cannot wear contact lenses if they need bifocal. But that is simply not true.
One common options is a monovision fit. In this type of fitting conventional contact lenses are used. What changes is the power of one of the lenses. Specifically, one contact lens is used for distance vision while the other one is corrects for near. This may sound like it would give you a big headache, but most patients get used to monovision almost immediately and then forget all about it.
While monovision is very successful, it does have its limitations. Specifically, since one eye is set for reading the distance vision in that eye is poor. And there can be a loss of depth perception. However, there now many good bifocal contact lenses available today.
These bifocal contact lenses are soft lenses and generally use what is referred to as a simultaneous vision. That means that the lenses use both distance and near vision at the same time. It may sound like your brain must determine which area of the lens to emphasize and which area to ignore. And while that is true to some extent, most patients get used to this type of vision in a very short period of time.
There are many types of bifocal contact lenses on the market today and one can usually be found to fit just about anybody's needs. And these are the kinds of contact lenses I fit in my practice every day.
