Drugstore reading glasses will not damage your eyes, and for plenty of people they work fine as a spare pair in the car or the kitchen drawer. The limits are worth knowing, though.
Off-the-rack readers use the same strength in both lenses, and most people's eyes are not identical. They do not correct astigmatism, which is very common. And the center of each lens is placed for an average face, so if your eyes sit closer together or farther apart than average, you can end up with tired eyes or a headache after a long stretch of reading.
There is a bigger point, too. Needing readers for the first time, usually somewhere in your forties, is a normal change in the lenses inside your eyes. It is also a good reason to have an eye exam, because that visit checks the health of your eyes, not just the strength you need.
Keep the drugstore pair if you like it. If reading still feels like work, give us a call at (865) 584-0905.
