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.

What is the small black dot in my eye?

User Avatar

Asked by Wiki User

The small black dot in your eye is most likely your pupil, which is the opening in the center of the iris that allows light to enter the eye. The size of your pupil can change in response to different lighting conditions. If the black dot appears to move or change shape, it could be a floater, which is a small piece of debris floating in the vitreous fluid inside the eye. If you have concerns about your eye health, it is best to consult with an eye care professional.

How big are owls eyes?

User Avatar

Asked by Wiki User

They are very large. In fact, they take up so much of the owl's skull that there is no room for the muscles (such as human beings have) to move the eyes around. This is why an owl is able to swivel its head around to such a great extent (almost 180 degrees)

On average, owls can rotate their heads 270 degrees. If humans had eyes in proportion to an owls, our eyes would be the size of saucers. NF
