Eyes

The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.

Can you see if your eyes are numb?

User Avatar

Asked by Wiki User

No, you cannot see if your eyes are numb as numbness is a sensory perception that you cannot visually confirm. Numbness is a lack of sensation, so you may feel it rather than see it. If you suspect that your eyes are numb, it is best to consult a doctor for a proper assessment and treatment.

How is it useful when cats eyes flash in the dark?

User Avatar

Asked by Wiki User

Cats have a layer of specialized cells in their eyes called tapetum lucidum that reflects light, allowing them to see better in low light conditions. When their eyes flash in the dark, it's the light reflecting off the tapetum lucidum, helping them to see in the dark by maximizing any available light.
