Farsightedness is a refractive error. Because the eyeball is too short (from front to back) or the cornea is too steep, light does not refract (bend) properly as it travels through the eye.
Most farsighted people have clear distance vision, but their near vision is blurry.
Symptoms include eyestrain, headaches, or difficulty reading.
Farsightedness is easily corrected with eyeglasses, contact lenses, or refractive surgery.
