Document Summary

500 x more sensitive to light than cones. More prevalent on the peripheral visual field. Rods and cones have different anatomy and functions. Light comes into eye and goes through all the cells to hit rod and cones. Then signals sent out through the layers then sent out to optic nerve. Visual acuity is our ability to see fine details. 400 nm purple, 500 nm yellowish green, 570nm yellow. You want to see a dim star at night where should. Best to look with peripheral vision for stargazing. Right visual field goes to left hemisphere, left goes to right. Photoreceptors, rods, and cones have action potential that are. Thalamus then sent to thalamus . end result is visual cortex. Image is projected upside-down and flipped left to right on the retina. If any of the components are not working properly, result is a poor image. Wavelengths not absorbed (ex subtracted) are reflected to eye.
