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.

Do brown eyes see better in the sun than blue eyes?

User Avatar

Asked by Wiki User

Does your eye colour influence how you see?

It turns out that it does. The darker the eyes, the more light is absorbed as light waves pass through the eye, and the less light is available to reflect within the eye. Light reflection (scatter) within the eye can cause susceptibility to glare (eg. sun or headlights) and to poor contrast discernment. Thus it seems that people with darker eyes may have better vision in high-glare situations - perhaps this makes them better night drivers, for example.

Eye colour may also affect your colour vision. Here it seems that lighter eyes may provide some advantages.

So it seems to me that blue-eyed people should really go for dark-eyed partners - this way one can pick the paint colours, and the other can drive home at night.
