How does vision work?
When light rays pass through your pupil, the muscle called the iris (colored ring) makes the size of the pupil change depending on the amount of light that's available. You may have noticed this with your own eye if you have looked at it closely in a mirror. If there is too much light, your pupil will shrink to limit the number of light rays that enter. Likewise, if there is very little light available, the pupil will enlarge to let in as many light rays as it can. Just behind the pupil is the lens and it focuses the image through a jelly-like substance called the vitreous humor onto the back surface of the eyeball, called the retina.
What do converging lenses do to light rays?
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
Where does light first enters your eye?
Light first enters the eye through the cornea, the clear outer covering of the eye that helps to focus light. The cornea then bends the light and directs it through the pupil, the black hole in the center of the colored iris.
What bends light rays before they travel through the pupil?
The cornea
How do light rays travel to your eye from a lighted candle?
Light rays travel in straight lines from a light source, like a candle, and pass through the air until they reach your eye. Once the light rays enter your eye, they are focused by the lens onto the retina, where they stimulate the nerve cells to create an image.
What happens to light rays when they enter a concave lens?
When light rays enter a concave lens, they diverge or spread out due to the shape of the lens. The lens causes the light rays to refract, so they do not come together at a single point like with a convex lens. This spreading out of light rays is what makes concave lenses useful for correcting myopia or nearsightedness.
How are Light Rays Able To Pass Through The Pupil?
it passes though the pupil because your pupil is really sensitive and and strong heat can go right through it
What happens to the pupil when the eye focuses on distant objects?
The pupils' size change in response to the degree of light that is entering the. Dilation depends less on the distance of the object from the eye and more on how many light rays are in the field of vision.
