Refractive errors are a type of vision problem that makes it hard to see clearly. They happen when the shape of your eye keeps light from focusing correctly on your retina (a light-sensitive layer of tissue in the back of your eye).
Refractive errors are the most common type of vision problem.
Types of refractive errors.
There are 4 common types of refractive errors:
▪︎Nearsightedness (myopia) makes far-away objects look blurry
▪︎Farsightedness (hyperopia) makes nearby objects look blurry
▪︎Astigmatism can make far-away and nearby objects look blurry or distorted
▪︎Presbyopia makes it hard for middle-aged and older adults to see things up close
Causes of refractive errors.
Refractive errors can be caused by:
▪︎Eyeball length (when the eyeball grows too long or too short)
▪︎Problems with the shape of the cornea (the clear outer layer of the eye)
▪︎Aging of the lens
Symptoms of refractive errors
The most common symptom is blurry vision.
Other symptoms include:
▪︎Seeing a glare or halo around bright lights
▪︎Eye strain (when your eyes feel tired or sore)
▪︎Trouble focusing when reading or looking at a computer
If you have a refractive error, your eye doctor can prescribe eyeglasses or contact lenses to help you see clearly.
