Refractive Errors: Understanding Myopia, Hyperopia, and Astigmatism

Refractive errors are common vision problems that occur when the eye does not focus light correctly onto the retina. They can affect children and adults and may cause difficulties with reading, driving, studying, and other everyday activities.

What Are the Main Types of Refractive Errors?

Myopia (short-sightedness): Distant objects appear blurred, while nearby objects may remain clear.

Hyperopia (long-sightedness): Close-up activities may be difficult, and some people experience eye strain or headaches.

Astigmatism: An irregular curvature of the cornea or lens can cause blurred or distorted vision at different distances.

Presbyopia, an age-related reduction in near-focusing ability, is another common vision problem.

How Are Refractive Errors Diagnosed?

An eye examination measures how well you see and determines the lens power needed for correction. Your eye-care professional may also assess overall eye health to identify other conditions that could affect vision.

What Are the Treatment Options?

Depending on the individual's needs, refractive errors may be corrected with prescription glasses or contact lenses. Some suitable adults may consider refractive surgery after a detailed assessment of their eye health and prescription stability.

Children may need additional monitoring, particularly if their short-sightedness is progressing.
