Presbyopia usually occurs at around age 40, when people experience blurred near vision when reading, sewing or working at the computer.
You can't escape presbyopia, even if you've never had a vision problem before. Even people who are near-sighted will notice that their near vision blurs when they wear their usual eyeglasses or contact lenses to correct distance vision.
Signs and symptoms
When people develop presbyopia, they find they need to hold books, magazines, newspapers, menus and other reading materials at arm's length in order to focus properly. When they perform near work, such as embroidery or handwriting, they may develop headaches, eye strain or feel fatigued.
