What is the Difference Between an Eye Exam and Refraction Test?

The refraction test is a type of eye exam that measures a person's prescription for eyeglasses or contact lenses. It is usually done as part of a routine eye exam and can help your eye doctor determine what prescription you need for your eyeglasses or contact lenses. In today's busy world, it can be tempting to go to a local eyeglass store to see if you need eyeglasses, rather than making an appointment with an Oklahoma eye doctor and taking the time to have a complete eye exam. However, there are important differences between a comprehensive eye exam and a rapid eye test.

While it takes longer than a refraction test, having a regular comprehensive eye exam has obvious benefits, especially as you age. Vision Care Direct is a doctor-owned prepaid eye plan that helps ensure that your patients have healthy eyes. We offer many different plan designs that fit the patient's budget, and all of our plans include discounts on a comprehensive eye exam. Patients can decide where to go for tests and, together with you, they can decide which eyeglasses or contact lenses to buy.

Refractive errors are extremely common and account for about 80% of vision problems in the United States. The electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of light-sensitive cells in the eyes. A refractive error means that light doesn't bend correctly when it passes through the lens of the eye. This test will help your eye doctor determine if you need corrective lenses and, if so, what type of prescription you need.

After age 40 (or for people with a family history of glaucoma), eye exams should be scheduled at least once a year to screen for glaucoma. If this is the case, your eye doctor will determine what prescription you will need and will organize your corrective eyeglasses. You want what's best for your employees, but finding eye care services in Oklahoma and any state isn't always the easiest thing. Regular exams will help the eye doctor detect glaucoma and other eye conditions associated with aging and, if possible, treat them in time. This test requires the patient to read the letters from a chart located 20 feet away, starting with the top row and with one eye closed at a time.

There's a good chance that all or part of a patient's eye exams are covered by a standard vision insurance plan. Refractive errors are due to light from the eye not being reflected normally and not correctly reaching the light-sensitive cells in the back of the eye. All tests for a complete eye exam should be painless, and your eye doctor will explain what to expect and why each one is important. In conclusion, it is important to understand the difference between an eye exam and refraction test in order to make sure that you are getting the best care possible for your eyes. While refraction tests are quick and simple, they can leave many stones unremoved in terms of eye health.

It's important that your patients have regular comprehensive eye exams, and that these exams are affordable.
