SEEING PROGRESS HOW CAN I GET RID OF THESE READING GLASSES? THE STATE OF THE ART IN PRESBYOPIA CORRECTION AUTHOR John Meyer, MD W hen we’re young, we often don’t realize how good things are until time passes and things change. Being able to wake up and just go about our day without even realizing we have eyes is normal for most people. Some of us need glasses for distance vision, but one pair of glasses or contact lenses work well the whole day until around age 40. Then, almost overnight we cannot see to read without holding material at arm’s length, and eventually our arms are too short. At this point, we are tied to reading glasses or bifocals. This is often the earliest indicator of our aging and even though it is not possible to slow aging, it would be nice not to be reminded several times a day of that fact. Cheaters are great for improving reading vision, but they make distance vision worse and need to be put on and taken off many times a day as needed. They are hard to keep track of and require taking hands off one’s work to put on. Bifocals are a nice tool, allowing reading and distance vision with one pair of glasses, but they also require compromises. Only a portion of the lens will focus for each distance, and one needs to look through different parts of the lens to see different distances. Golf, seeing the front and back sights of a gun and other activities requiring vision of different distances at the same time are adversely affected by bifocals. Monovision contact lenses also work well, but depth perception is lost with monovision. Multifocal contact lenses are also pretty good these days but quality and sharpness of vision may not be great, and allergies and dryness also cause problems. Surgical options exist. LASIK can provide monovision but with the same loss of depth perception as monovision contact lenses. (continued on page 26) JUNE 2019 25
