What is the difference between farsightedness and nearsightedness?

Farsightedness (hyperopia) and nearsightedness (myopia) are classified as refractive errors. Astigmatism (blurred or distorted vision at all distances) is also a refractive error. Refractive errors are the most common eye problems and are easily corrected. The National Eye Institute estimates more than 150 million Americans are affected by one of these conditions.

Farsightedness is when nearby objects appear blurry, but you can see distant objects clearly. In addition to having trouble seeing things up close, other symptoms of farsightedness include eye strain and headaches. Many people are born with farsightedness, but vision problems may not present themselves until later in life.

Nearsightedness is when you have trouble seeing objects farther away, but anything near appears clearly. Headaches, eye strain, and squinting are some symptoms of nearsightedness. Some people affected with nearsightedness also have blurry vision when the light is dim, such as during nighttime driving. Nearsightedness normally develops during childhood.

Schedule an appointment with an eye doctor if you experience symptoms associated with either condition. An eye exam will determine which issue you have. The most common treatments for farsightedness and nearsightedness are contact lenses or eyeglasses. Surgery may be required depending upon the extent of the problem.
