The basic goal of refraction is to focus light rays from optical infinity on the retina through the application of corrective lenses placed in front of the eye. To restate that in functional terms, one could say that the refractionist's main goal is to provide lenses that will allow not only clear, but comfortable vision. That.

A refraction is an eye exam that measures a person's prescription for eyeglasses or contact lenses. How the Test is Performed. This test is performed by an ophthalmologist or optometrist. Both of these professionals are often called "eye doctor." You sit in a chair that has a special device (called a phoroptor or refractor) attached to it. You.

This book is appropriate for medical students, optometry.
The chapters on the Maddox Rod and Cover/Uncover Test are obsolete, as the new style refraction exam excludes these stations (since ). The book also assumes that the candidate sitting the exam will be using "plus cylinders", which is not the case for everyone (depending who teaches you). Overall a good guide/5(9). By measuring this zone, the autorefractor can determine when a patient’s eye properly focuses an image. The instrument changes its magnification until the image comes into focus. The process is repeated in at least three meridians of the eye and the autorefractor calculates the refraction of the eye, sphere, cylinder and axis.

Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves in deep water travel faster than in shallow. If an ocean wave approaches a beach obliquely, the part of the wave farther from the beach will move faster than that closer in, and so the wave will swing around.
