Entrance Pupil Lenses
The entrance pupil is the apparent aperture as seen from the object side.
entrance pupil
The entrance pupil is the image of the lens’ aperture stop as seen from the front of the lens — through the glass elements in front of the iris — and that is normally where the iris is located.
Direct Reflection
Direct reflection—also known as specular reflection—is the mirror-like reflection of a light from a surface in which the light from a single incoming direction is reflected in a single outgoing direction.
Consensual Reflection
The consensual reflectionis any reflection observed on one side of the body when the other side has been stimulated. This reflex is evidenced mainly in the process of contraction of the pupil of both eyes by illuminating only one of them (Dictionary, 2017).
Alternate Pupil Reflex
Light Response Pupil Test. The light response pupil test assesses the reflex that controls the size of the pupil in response to light.
Visual Field Defects Retina
Lesions that affect the inferior portions of the visual system (in the retina, optic nerve, or even visual cortex) cause superior visual field defects.
