Reasons To Have A Refraction Eye Examination

There are many routine eye examinations that you can have each year. One of them is a refraction test. Although this is part of the routine exams that you are typically given when you go to an optometrist, it tends to fall under the category of a vision test. This type of test can determine the quality of your eyesight, and then help you diagnose any problems that you may currently have. This is the test that will be given to anyone that potentially needs to have eyeglasses. It allows the optometrist to determine what the prescription will be. To schedule your refraction eye examination, follow these simple suggestions.

What Happens During A Refraction Eye Examination?

Almost everyone who has gone to the eye doctor before has gone through this type of testing. There is likely a chart that will be on a wall, usually about 20 feet away, and you are required to read the lines that they are telling you to read. In most cases, there will be letters that you will see, going across horizontally, and they will have you look through what is called a phoropter. Once this is in session, the eye doctor will begin to change the lenses, eventually leading to the one that allows you to see as clearly as possible. Based upon the settings, they will know how to create the eyeglasses or contacts that you will wear that will ensure clarity wherever you happen to be looking.

How Often Should This Be Done?

In most cases, people will go through this type of testing on an annual basis. The prescription for your eyeglasses will often change due to environmental or personal circumstances. For example, if you have changed jobs recently, requiring you to look at a computer screen, this can affect the quality of your vision dramatically. Therefore, if you are going to set an appointment with an optometrist, you can likely expect to go through this type of testing.

If you have not had this eye examination before, it might be time to see just how good or bad your vision actually is. If it is determined that you have perfect vision, you will not need a prescription, yet many people do need to have some type of glasses. Whether you are nearsighted or farsighted, this testing will help the optometrist determine what will be the best option for you.
