Computerized Refraction Q & A

What is refraction?

To understand refraction and how it relates to vision, you need to understand how light travels. Light moves in rays that bend — or refract — when they pass through lenses or water. Your cornea and intraocular lens both refract light as it enters your eye, focusing it on your retina. Your retina then converts that light into electrical impulses that are sent to your brain to be interpreted for vision.

When there is an abnormality in the shape or curvature of your eye, the refraction of light is distorted, impairing your vision.

What is a computerized refraction test?

Refractive errors that cause blurry vision are the main reason most people schedule appointments with eye doctors — although you should have your eyes checked at least once every other year if you have accurate vision, or once a year if you wear corrective lenses or have other eye health problems.

At In Focus Vision Center & Eyecare, your optometrist uses a computerized refraction test to determine if you need to wear corrective lenses as well as the exact prescription required. A computerized refraction test shows your doctor how light bends as it travels through your eye. You gaze into a machine that shines a light into your eyes and then measures the amount of light they reflect.

What are refractive errors?

A refractive error is when an abnormality in your eye distorts the way light bends when it passes through your eye to your retina. Refractive errors are due to the length of your eye and the curvature of your cornea and intraocular lens.

Depending on the shape of your eye, you may develop myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. Presbyopia is another condition that develops as your intraocular lens stiffens with age, making it difficult for you to focus on nearby objects like cell phones, computer screens, or books.
