When do I need reading glasses?
Just about anyone in their 40s and beyond will, at some point, need reading glasses.
Reading glasses help compensate for diminished vision related to presbyopia, the normal age-related loss of the ability to focus on up-close objects, such as words in a book or a text message on a smartphone.
the lens power of over-the-counter reading glasses typically ranges from +1 to +4.
Over-the-counter reading glasses are an acceptable option for people who have good distance vision.
Alabama optometrist Dr. Samuel Pierce, past president of the American Optometric Association, says over-the-counter reading glasses — which can be purchased at drugstores, department stores and other general retailers without a prescription — are designed for short-term wear, and are best suited for people who have the same lens power, or strength, in each eye and don’t have astigmatism.
