Understanding the Refraction Test: A Comprehensive Guide

A refraction test, also known as a vision test, is performed by an optometrist to determine your eyeglass prescription or the corrective lenses that you need to improve your vision. The test measures the way that light waves are focused or refracted by your eyes. This information can identify if you have problems with your eyes’ ability to focus, which can include nearsightedness, farsightedness, astigmatism, or presbyopia.

Before you undergo a refraction test, it is essential to speak with a qualified optometrist who can explain the procedure and answer any questions you have. One such expert is Dr. Dolan, an optometrist at 20/20 Vision in Rochester Hills, MI. Dr. Dolan has extensive experience in the field, and his practice is focused on providing comprehensive eye exams and corrective lenses to his patients.

During a refraction test, you will be asked to look through a device called a phoropter, which contains different lenses. The optometrist will ask you to compare the images and determine which set of lenses provide the clearest vision. This process is repeated several times to determine the optimal prescription for your vision.

While undergoing a refraction test, it is important to be honest with your optometrist about what you are experiencing. They may ask you to identify when the letters on the eye chart become blurry or when the lines merge together. This information helps them to find the correct lenses for your eyes.

In addition to providing you with the correct prescription for your eyeglasses or contact lenses, a refraction test can also help detect eye problems such as cataracts, glaucoma, or retinal disorders. It is recommended that everyone receives a comprehensive eye exam, including a refraction test, at least once every two years.

If you have any questions about your vision or need to schedule a refraction test, do not hesitate to contact Dr. Dolan at 20/20 Vision in Rochester Hills, MI.
