amplitude /am·pli·tude/ (am´plĭ-tldbomacd)
amplitude of accommodation (AA),
1. largeness, fullness; wideness in range or extent.
2. in a phenomenon that occurs in waves, the maximal deviation of a wave from the baseline.
amplitude of accommodation amount of accommodative power of the eye.
am·pli·tude of accommodation ( m pl -t d )n. The difference in refractivity of the eye at rest and when fully accommodated. |
amplitude of accommodation (AA),
the total accommodative power of the eye, determined by the difference between the refractive power for farthest vision and that for nearest vision.
accommodation
adjustment, especially adjustment of the eye for seeing objects at various distances. This is accomplished by the ciliary muscle, which controls the lens of the eye, allowing it to flatten or thicken as is needed for distant or near vision.
amplitude of accommodation
the total amount of accommodative power of the eye.
histological accommodation
changes in morphology and function of cells following changed conditions.
