What prescriptions can be corrected with contact lenses? What if I need bifocals?

Near-sightedness, far-sightedness and/or most astigmatism can be corrected with contacts.  There are also options for people who need bifocals, such as monovision or multifocal contact lenses.  Monovision is when we correct one eye to see far and the other eye to see close range.  The brain learns to pay attention to the clear image of what you are trying to see.

About 75% of those who try this system like it; some will even have laser surgery to make it permanent!  Multifocal contact lenses, instead of being built top-to-bottom like spectacles, generally hold the strongest power in the center of the lens and gradually decrease to the edges.  They take advantage of the way your pupils naturally work—smaller for seeing close and bigger for seeing far—so you get proportionally more power depending on your pupil size.  As you might imagine, this also means that proper lighting is essential.  Reading a menu in a dim restaurant will be difficult with these lenses, as will trying to read highway signs when driving into the sunset.
