During the second part of sensory physiology, students study the anatomy and physiology of the eye. Some characteristics students learn about are accommodation, the near point of vision, astigmatism, the blind spot, and color blindness. Students also use a Snellen Eye Chart to measure their visual acuity.>
Next, students look at the geomentry of the visual field using a perimeter and a color wheel. After mapping their lab partner's visual field, students will see if this field is a perfect circle or not.
The teaching assistants also lead each group through a sheep eye dissection so students can observe the anatomy of the eye hands-on, in greater detail.
