Explain the electromagnetic spectrum and its relevance to visual perception. Give the specific range of human sensitivity and possible reasons why we are not sensitive to the entire spectrum. |
|
|
|
Understand where eyes should be placed on the head and how they should move. Describe the anatomical musculature of the eye and how it functions to produce eye motility. Discuss the importance of eye movement to the survival of various species including humans. |
|

|
|
|
Describe in detail the structure, location, and function of the retina. |
|
|
|
Explain the retinal circulatory system and its necessity to the visual system. Include problems that can disrupt circulatory system function and the ramifications of such disruption. |
|
|
|
Describe how image formation occurs in the human eye including how the eye achieves optimum image sharpness through accommodation. Include the role of light convergence and divergence in the explanation. |
|
|
|
Distinguish between hyperopia, myopia, and astigmatism including the symptoms, causes, and possible remedies of each. |
|
