What is the function of the Human Visual System in processing light?
Light passes through lens, focused on retina, goes to the brain for processing
What is a potential concern related to the Human Visual System described in the text?
The existence of a blind spot due to the capture of light by the retina and passage of optic nerves
What is an essential characteristic of a well-constructed model in the context of human performance?
It captures essential pieces without overfitting or underfitting
What is the function of rods in the retina?
Sensing intensity or shades of gray
What is the main implication of the distribution of photopigments in the retina?
Reduced sensitivity to blue light
Why does the lens yellow with age and absorb short wavelengths?
To decrease sensitivity to blue light
