A refraction eye exam, otherwise known as a vision test, is used to determine your prescription. This is common practice when performing an eye exam, as it will help the doctor determine exactly if and what prescription you require. It can also be crucial in determining the possible presence of an eye disease.
So what exactly is a refraction eye exam? A person who does not have 20/20 vision has what is called a refractive error. This means that the shape of your eye does not allow the light to bend properly while passing through the lens, resulting in a blurry image. These errors are commonly associated with farsightedness, nearsightedness, and astigmatism. Your doctor can test this in one of two ways by either shining a light directly into your eye or by using a computerized refractor, which uses a machine to determine your refractive score. The refraction test allows your doctor to determine if you need a prescription lens as well as detect any possible diseases. This is very important for monitoring the health of your eyes.
