Nearsightedness is an eye condition in which you can see nearby objects clearly, but faraway objects appear fuzzy or blurry. Nearsightedness is also called myopia. Nearsightedness is extremely common and very treatable. According to the American Optometric Association (AOA), almost 30 percent of adults and children in the United States are nearsighted.
According to the National Eye Institute (NEI), myopia is usually diagnosed between the ages of 8 and 12. (NEI) Your eyes are growing at this age, so the shape of your eyes can change. Adults usually remain nearsighted if they have the condition as a child. Adults can also become nearsighted due to certain health conditions, such as diabetes. Visual stress can also be a risk factor for nearsightedness. Visual stress is eyestrain from doing detailed work, such as reading or using a computer. Nearsightedness can also be an inherited condition. If one or both of your parents are nearsighted, you are likely to be as well.
The most obvious symptom of nearsightedness is blurry vision when looking at faraway objects. Children may have trouble seeing the blackboard at school. Adults might not be able to see street signs clearly while driving. Other signs of nearsightedness include:
1. Headaches
2. Eyes that hurt or feel tired
3. Squinting
The symptoms of nearsightedness usually go away after treatment with eyeglasses or contact lenses. Headaches and eye fatigue may linger for a week or two as you adjust to your new eyeglass or contact lens prescription.
