A parabolic mirror best focuses light onto a spot. Or a convex lens will do similar.
In the eye, the lens towards the front of the eye focuses light onto the retina, where the light sensitive cells lie.
im guessing you mean, what focuses light rays. Your answer is nothing. Light naturally spreads, bounicing off objects in the air and around you. :)
The lens is the part of the camera that bends the light and does the focusing.
A Convex Lens
The lens focuses light on the retina.
retina, film, CCD, etc.
Yes the lens focuses the light to the back of the eye, the retina, which has rods and cones. rods-sharpness and grayscale and cones-color.
There are three primary elements; the primary mirror that magnifies the incoming light, the secondary mirror which directs the light into the eyepiece, and the objective lens, which focuses the light into an image.
some part of light reflected from the chair enters our eyes
condenser - lens system that aligns and focuses the light from the lamp onto the specimen diaphragms or pinhole apertures
Cornea: Transmits & focuses light into the eye. Lens: Focuses light rays onto the retina. Retina: Creates impulses to the brain. Thepupil is a hole located in the center of the iris of the eye that allows light to enter the retina.
The list of choices you included with your question doesn't include any part of atelescope that can do that. I would have picked the objective, whether a lens ora mirror.
The pupil goes larger in the dark, and smaller in the light.
The biconvex transparent structure that focuses light on the retina is called the lens.
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.

The lens focuses light on the retina.
It focuses visible light.
The lens focuses light on the retina (fish have one)
The lens focuses light by bending the light to make it strike the retina in the right angle
