The muscles in your eyes work hardest when you focus on close-up or detailed work, like when you’re reading or working at the computer. If your near vision is poor, those muscles work even harder to help you see clearly. Because that isn’t a natural position for the eyes, they can get tired, which makes you feel sleepy. If reading glasses alone don’t help, try blinking more often or pushing your computer further away from you. This will help to relax your eyes.
