The steps of light being received by the eye are:
generation of light
passage of light to the eye
through the tear film
through the cornea
through the aqueous humor
through the lens
through the vitreous humor
through the layers of the retina
to the photoreceptors of the retina
The light enters the eye through the retina, or pupil.
Light first enters the eye when it strikes the surface of the cornea, the clear protective outer layer of the eye.
The outer layer of the eye is the cornea.
It gets filtered
You only "see" when light enters your eyes. In the dark, there is no light . . . the main reason why we call it "dark". Since there is no light, none can enter your eyes, and you do not see.
Light rays enter the eye through the cornea.
first of all, how can you have gray eyes!second of all, it would probably have brown hair, and green eyes.
The light wakes you up because you are very sensitive to the light when you first wake up. Your eyes have been in darkness for a long period of time and now light is hitting them.
The pupil in your eye (the black center) is what controls how much light is allowed to enter your eye. The wider the pupil is, the more light is let in. When your eyes feel sensitive to light, it is because the pupil is letting in excessive light. Sometimes, it is a neurological event that makes your eyes sensitive to light, such as a migraine headache. In any case, the area of the brain that is affected by light sensitivity is the portion that is dedicated to the processing of visual information, and that is the occipital cortex.
The light bounces off the object to get into our eyes. Actually there are many beams of light, but they don't all reach to your eyes.
It must enter our eyes.
Lights enters your eyes directly from a light source or it reflects off other objects

Because the lens has been focused depending on the available light. if you enter a darker room, your eyes have to re-adjust to allow more light through them.
paagal cota
Yes
it is to help let as much light into your eyes as possible so you can see the best you can. this is why our pupils enlarge in the dark
Light from the sun(:
not material, but color. the color black absorbs all colors in light and reflects no light to enter your eyes. black is only visible by contrast on other things you can see.
