Want this question answered?
false
No. But small sections of lenses behave like prisms.
That's a "lens".
well.......Its like testing a conjecture and finding a statement true or false because u have to test it!!! to see if its true or false and its different,true is like something u can prove and false is untrue and u cant prove it. :D i know i don't make sense but that's how i explained it on my homeworklol
Something like "Write a false statement".
The cornea or lens of the eye.
No, the anterior part of the cornea does not function as a contact lens. The cornea is the clear, dome-shaped front part of the eye that helps to focus light onto the retina. Contact lenses are external devices that are placed directly onto the cornea to correct vision or change its appearance.
It changes the shape of the cornea, which changes the focal length. Both the cornea and the lens act together (like a compound camera lens) to focus the image on the retina.
If you have photographic memory then your eye functions like a camera in a way
The eye can be broken down into two chambers. The anterior chamber is the area between the cornea (the clear, front surface of the eye) to the lens. It contains the watery aqueous humour. The posterior chamber is the area from the back of the lens to the retina. This contains the jelly-like vitreous humour.
first learn about the power of each elements of human eye like cornea, lens...then we can get the commercial lens and can be mounted in mechanical assembly.
The eye. Astigmatism is when the cornea (the clear dome that covers the pupil) or the lens of your eye is not its usual perfectly round shape. Instead it's an oval shape, a bit like a rugby ball.
There are two "humours" in the eye. The aquious (I think I misspelled it) is a fairly light liquid between the cornea and the lens. Between the lens and the retina is the vitreous humour, a viscous, jelly like substance.
The light heats it up to the point where it undergoes a mini-explosion, and is then referred to as a "popcornea". Just kidding. The cornea is transparent, and does nothing else except transmit and focus light, a function a bit like that of the crystalline lens behind it.
It's actually called the lens, which is in the cornea.
The cornea is the clear front surface of the eye, which acts like a camera lens, and allows light through to reach the retina.
The cornea is a tough, clear covering that keeps objects from entering the pupil.The Cornea is the front part of the eye that covers the iris and the pupil.help keep your eye cleanKeeps dirt , germs and grit out of your eye it is like the protective cover for your eye.It refracts light together with the lens.Because the cornea is as smooth and clear as glass but is strong and durable, it helps the eye in two ways1. It helps to shield the rest of the eye from germs, dust, and other harmful matter. The cornea shares this protective task with the eyelids, the eyesocket, tears, and the sclera, or white part of the eye2. The cornea acts as the eye's outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65-75 percent of the eye's total focusing power.When light strikes the cornea, it bend-or retracts-the incoming light onto the lens. The lens further refocuses that light into the retina, a layer of light sensing cells lining the back of the eye that starts the translation of light into vision. For you to see clearly, light rays must be focused by the cornea and lens to fall precisely on the retina. The retina converts the light rays into impulses that are sent through the optic nerve to the brain, which interprets them as imagesThe cornea allows light to enter the eye.Because the cornea is as smooth and clear as glass but is strong and durable, it helps the eye in two ways 1.

I was told the cornea are the muscles that control dilation of the iris, controlling the amount of light that is allowed to enter the eye.The reason it is colored is due to genetics. Specific amino acids produce different colors (including people like myself who's color changes, which is affected by additional acids in the food we eat).
