Refraction is a test that optometrists and ophthalmologists use to measure a person's refractive error. a refractive error is when your eye does not bend light coming into your eye properly as it passes through the cornea, the crystalline lens and fluid media to come to a sharp, clear focus onto your retina.

Retinoscopy: One of the most common instruments used for objective refraction is the retinoscope. Using a retinoscope, your doctor will project a streak of light into your pupil. A series of lenses are flashed in front of your eye. By looking through the retinoscope, your doctor can study the light reflex of the pupil.

It is called manifest because it the measure of the refraction before any eye drops are instilled or anything else that could alter the measurement. It is a measurement as the patient is in real life. A manifest refraction can be performed using a traditional manual phoropter or an automatic phoropter.

Cycloplegic refraction - A cycloplegic refraction is a procedure used to determine a person's refractive error by temporarily paralyzing the muscles that aid in focusing the eye. Cycloplegic eye drops are used to temporarily paralyze or relax the ciliary body, or focusing muscle, of the eyes.

Refraction consists of two parts, objective and subjective. Objective Refraction. An objective refraction is a refraction obtained without receiving any feedback from the patient. An objective refraction is obtained by using different instruments. Your doctor will use a retinoscope or auto-refractor to measure your refraction without asking for subjective responses from you.

If you don’t have 20/20 vision, you have what is called a refractive error. A refractive error means that the light is not bending properly when it passes through the lens of your eye. The refraction test will tell your doctor what prescription lens you should use in order to have 20/20 vision.

Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina. 1  An example of refraction is a bending of the sun's rays as they enter raindrops, forming a rainbow.

binocular refraction A clinical procedure in which the subjective measurement of refraction of each eye is performed while both eyes are viewing a test. The visual examination is thus carried out under more natural conditions than when one eye is closed; the sizes of the pupils are similar and the accommodation-convergence relationship is maintained.
