Refraction Tests with our Fair Lawn Optometrists
One of the best ways to make sure your eyesight stays in good health is by taking advantage of an eye exam in Fair Lawn NJ. There are a variety of tests that can be performed during a regular eye exam, including ones that test for nearsightedness and farsightedness. Another type of test that can be performed is a refraction eye test.
What Is an Eye Refraction Test Used For?
Usually conducted as part of a regular eye exam, a refraction eye test gives the eye doctor a precise prescription regarding the lenses you need in eyeglasses and contacts. If you have poor vision, whether it is from astigmatism, nearsightedness, or farsightedness, you will need a refraction test to determine the prescription you need. A refraction test assesses the eyes for a refractive error – light that is not being properly bent once it passes through the eye’s lens.
What To Expect During the Exam?
A refractive eye test is conducted with and without the use of a computerized test. With a computer, you simply look through an auto refractor and it takes measurements regarding any light that is being reflected by the retina. Without a computer, our eye doctor shines a light at the eyes and assesses how much is bouncing off the retina. In doing so, our eye doctor can calculate a refractive score, which can then be used to calculate a prescription. There are other processes involved in a regular eye exam, including pupil dilation and checking for astigmatism. Your exam will also be influenced by whether or not you choose to take advantage of prescription glasses or contacts. If so, you will pick out your frames or contacts and then come back for a follow up appointment several weeks later to ensure your frames or contacts are working properly.
