Monovision for Presbyopia: Seeing Better as You AgeJuly 18, 2013
Growing up, you might have noticed Mom or Dad, who never wore eye glasses in the past, pull out reading glasses to analyze the newspaper or to read food ingredients.
There’s a good chance presbyopia was the culprit.
About 90 million adults deal with presbyopia, the natural loss of one’s ability to see up close, which starts affecting people between the ages of 40 and 50. As we age, the eye’s natural lens starts to weaken in flexibility. It becomes harder for the eye to change focus and to read small print.
For these people, LASIK is often not considered an option because LASIK doesn’t correct for presbyopia. LASIK could fix someone’s distance vision, for instance, but reading glasses would still be needed to read up close. Bifocals might make a good solution to presbyopia, but there’s also a laser eye surgery option.
Called “monovision,” this procedure corrects one eye so the natural lens can see into the distance. But monovision leaves one eye nearsighted, or able to see up close. This way both eyes work in tandem for near and far vision.
Monovision can result in some loss of distance vision sharpness, depth perception and quality of night vision. So this laser eye surgery is not advised for those who enjoy prolonged reading or who read a lot of fine print.
But for people who want to be able to read a menu with ease, glance at the numbers of a price tag or read a document quickly, monovision can be an ideal alternative to reading glasses.
Before opting for monovision or any other laser eye surgery, discuss with your doctor. He or she will often recommend you try out monovision with a pair of eye glasses or contact lenses that mimic the results of the procedure. These will help you determine if monovision fits your lifestyle. If so, you might be a good candidate for the procedure.
