WebNerve problems can affect the nerves of the muscles surrounding the eyeball and those that control the dilation and contraction of the pupil. Such problems can result in symptoms such as double vision, nystagmus, oscillopsia and disorders of the pupils, such as anisocoria.

Pupil size and near power requirements determine the rate of flatting throughout the optics of a GP lens: for example, a larger pupil can capture more of the peripheral zone than a smaller pupil ( Figure 7 ).
WebThere are two significant optical axes of the eye – the optical axis and the visual axis, which are also referred to in literature as the pupillary axis and the line of sight, respectively. The optical axis is composed of an imaginary line perpendicular to the cornea that intersects the center of the entrance pupil. WebWe demonstrate a dual-MLA-based EPE that produces excellent exit-pupil uniformity and better than 90% diffraction efficiency for all three wavelengths in a color-display system. Two-MLA registration is performed with submicrometer precision by use of far-field alignment techniques.
WebMar 8, 2024 · Accommodation also leads to constriction of the pupil due to contraction of the sphincter pupillae and convergent eye movements caused by contraction of the medial, superior, and inferior recti which are all innervated by the oculomotor nerve. When focusing on close objects, the optical power of the eye's lens permits the eye to create clear ...
