Presbyopia usually occurs beginning 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 short sighted will notice that their near vision blurs when they wear their usual glasses or contact lenses to correct distance vision.
Presbyopia Symptoms and Signs.
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 craft work or handwriting, they may develop headaches, eye strain or feel fatigued.
What Causes Presbyopia?
Presbyopia is caused by an age-related process. This differs from astigmatism, nearsightedness and long sightedness, which are related to the shape of the eyeball and are caused by genetic and environmental factors. Presbyopia stems from a gradual thickening and loss of flexibility of the natural lens inside your eye.
Glasses with multifocal lenses are the most common correction for presbyopia, although multifocal contact lenses are becoming more prevalent.. Multifocal progressive glasses offer a more gradual visual transition between the distance and reading prescription, with no visible line between them.
Reading glasses are another choice, and are typically are worn just during close work.
