Question

How are we able to sense light even with the eyes closed?

Answer 1

Because our eyelids are not completely opaque. A small amount of light is still able to get through the skin.

Answer 2

Because our eyes have receptors called rods which is used for night vision. When our eyes are closed, it simulates nighttime conditions. The light which passes through the lids are easily picked up by the rods which sends messages to the brain, alerting us to the presence of a light source.

Answer 3

Our upper eyelid is very soft and thin. Moreover they are not completely opaque.Hence we can sense the light with closed eyes.

Like passing a beam of light through white paper.....

Answer 4

People who are not sighted can "sense" light, too, so I believe it has something to do with our circadian rhythm.

Answer 5

The eyes never actually close. The lid that covers the eye is translucent and allows some light through. The red or pink tint observed is caused by a combination of the skin and blood vessels absorbing the light and it being allowed through to your lens.

Answer 6

There are two types of light-detecting cells in our eyes. These are the rods and cones. Rods sense color and detail, while cones detect only shades of gray. The cones are used at night because they can sense smaller amouts of light, which is why we can only se shades of gray at night.

When we close our eyes, our eyes switch to using cones because of the darkness created by our eyelids, and the small amount of light that comes through is still detected.

If you close your eyes and look into a light, though, it will apear reddish, not gray. This is because not all rods are off, and not all cones are on. It is a mix of mostly cones and you can pick up the redish tint. created by passing light through skin. The same color appers if you put your fingers over a flashlight, because that color's wavelength is the only wavelength allowed through human skin.

Answer 7

any light absorbing surface, let it be our body itself, absorbs and transmits light.

light consists of seven colours. the absorbing surface absorbs that colour which matches the colour other than its surface colour and transmits the colour the colour that matches its surface colour.

that is the main phenomenon due to which we r able to see objects.

when it comes to our eyes, even when our eyes r closed, the skin on our eye transmits red colour ( which is the colour of the blood inside) and hence it falls on our retina.

this impulse enables us to sense light even when our eyes r closed
