- refractive errors are created by differences in the axial length of the schmatic eye
- Otherwise normal eye that is either too long for its optical power or too optically powerful for its axial length
- measures the plane angle between 2 radii of a circle that cuts off on the circumference of an arc equal in length to the radius
- let the subject compare a reference light with fixed wavelength + radiance. your test light of different wavelength is in a bipartite field. the subject would then adjust the..
- a measure of the luminous flux incident on a surface per unit area
- correcting ametropias with CLs changes the optical power of the refracting surface, and thus changes the
