- 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.
- the total radiant POWER emitted from a source or passing through a region of space
- 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
