ametropias corrected with spectacles at the anterior focal point of the eye; the light ray passing through the center of the spectacle lens is
if the light source is polychromatic, the total luminous power is equal to the
Uniform diffusion of the incident radiation such that its radiance or luminance is the same in all directions.
for uncorrected axial ametropias, list the size of the retinal image formed from largest to smallest
heterochromatic flicker photometry: once the flicker disappears or is minimized...
the chief ray goes through the center of the
used to correct for the differences between radiometric and photometric measurement across wavelengths
correcting an ametropia with CL: assume the optical center of the CL corresponds to the eye's
radiant intensity is usually associated with
monochromatic lights add together in a ____ fashion
located at the dioptric mean of the two focal lines (NOT the average distance)
radiant power emitted per unit solid angle, traveling in a given direction
the total radiant power (time rate of energy flow) emitted from a source or passing through a region of space
radiant power reflected or emitted from a surface per unit area and per unit solid angle.

when the accommodative amplitude or demand is measured with respect to the eye's principal plane
amount of accommodation exerted in dioptric power to move the focus from the far point to the near point
represents the earliest stage at which symptoms or clinical findings document the near vision effects of the condition
true or false: for a myope, the required amplitude at the ocular plane is less that that of the spectacle plane
simply the sum of bifocal add power and physiological accommodative amplitude when they are used together
