1987) that observers with reduced acuity are better able to resist optical blur, our older observers required lenses of somewhat greater dioptric
power to degrade acuity to 20/30 and 20/40 levels.
reduced peak velocity) to a change in dioptric

Fitted with a fast focus eye piece, dioptric
correction is -3 to +2.
Correction from +5 to -5 from +5 to -5 Exit Pupil Distance 15mm 15mm Focusing Range 4.
From the micrographs, facet diameters, lengths of dioptric
structures, retinal widths, and interommatidial angles were measured.
Proximal accommodation is accommodation that is introduced by awareness of the nearness or apparent nearness of the fixation object independent of the actual dioptric
Like other Sure Shot cameras, the 130u II model is equipped with a wide range of useful standard features including automatic film loading, auto advance and auto rewind, together with a self-timer function, manual exposure compensation, a dioptric
correction adjustment for the zoom viewfinder and optional mid-roll rewind.
The FluidVision IOL (PowerVision Inc, Belmont, CA) consists of fluid-filled haptics connected to a hollow optic; on ciliary contraction fluid is pushed into the optic increasing its curvature and dioptric
Provided that each of the three compared instruments measures the curvature of the cornea instead of its dioptric
power, the same keratometry index (1.

The least-studied accommodative effect in TBI has been dynamic accommodative infacility, which is diagnosed when a patient exhibits a slowed accommodative response to a change in either dioptric
lens power or target distance that can occur either alone or in conjunction with either accommodative insufficiency or excess .
