refraction

 [re-frak´shun]
the act or process of refracting; specifically, the determination of the refractive errors of the eye and their correction with glasses.
the deviation of light in passing obliquely from one medium to another of different density.
cycloplegic refraction a type of static refraction, measured after lens accommodation is paralyzed by administration of cycloplegic eye drops.
double refraction refraction in which incident rays are divided into two refracted rays.
dynamic refraction refraction of the eye during accommodation.
ocular refraction the refraction of light produced by the media of the normal eye and resulting in the focusing of images upon the retina.
static refraction refraction of the eye when its accommodation is paralyzed.

cycloplegic refraction
