Part I
1. Central vision is used to read, drive, and see pictures or faces and allows a person to see
shapes, colors, and details clearly and sharply. During the visual field test, Samantha’s central
vision is focused on the light straight ahead.
2. The light rays from the object in Samantha’s central vision are focused on the macula in the
center of the retina.
3. The peripheral vision is the side vision that allows the eye to view objects on either side of
the body. The objects in Samantha’s peripheral vision hit the rods, which are on the outside
of the macula of the retina.
4. The optic disc, which is called the blind spot, is responsible for the physiological blind spot
because it contains no rods or cones.
5. Please see below:
6. Aqueous humor (transparent watery fluid) nourishes the lens and cornea.
