Manifest refraction - A manifest refraction is the most traditional way of measuring one's refractive error. As mentioned above, it is usually the part where the patient is shown choices and is involved in the process.
Noun. 1. refraction-the change in direction of a propagating wave (light or sound) when passing from one medium to another. physical phenomenon-a natural phenomenon involving the physical properties of matter and energy. birefringence, double refraction-splitting a ray into two parallel rays polarized perpendicularly.. the change of direction of a ray of light, sound, heat, or the like, in passing obliquely from one medium into another in which its wave velocity is different. 2. a. the ability of the eye to refract light that enters it so as to form an image on the retina. b. the determining of the refractive condition of the eye.
