READING GLASSES VS. CONTACT LENSES
Many patients who wear reading glasses ask me if they are able to wear contact lenses, and really patients with reading glasses have three options; The first option is to wear what is called mono-vision. Mono-vision means there is one reading contact lens worn usually in the non-dominant eye. The second option is a bi-focal contact lens, again usually in the non-dominant eye. And the third option would be two bifocal contact lenses.
The advantage of the mono-vision is that the one eye with the reading lens can see very well near, however it’s a little blurry far away. The idea is that the brain will rely on the distance eye, the right eye, so they will use that to see far, using the contact lens eye to read. With the bifocal contact lens, which is a slightly more complicated fit, we still leave the dominant eye focused far with no contact lens and then the bifocal lens tricks the brain into thinking the non-dominant eye has both distance and near vision. When we fit contact lenses in our office, we always do a trial, because we’re never sure whether the patient will be satisfied with the quality of vision they obtain.
