Reading glasses work like a magnifying glass, which means the edges are the thinnest point while the middle is much thicker. This helps enlarge the text you're reading and makes it easier for your eyes to focus on words and objects up close without needing to hold them far away. If you're having trouble reading text messages on your cell phone, reading glasses can help. If you have complaints, e.g. headaches when working on the screen, you may need blue light filter glasses.
