Lenses can correct vision problems by bending light rays before they reach the eye, in effect moving the focal point of the eye's lens so that it falls upon the retina and creates a clear image. Concave lenses cause light rays to converge and lengthen the focal point for the near sighted eye. Concave lenses are thinner in the middle and thicker on the edges and may be curved on one or both sides. Concave lenses cause light rays to diverge, or spread apart. :)
What else can I help you with?
What is the shape of the eyeball if you are nearsighted?
Glasses for nearsighted people are convex. That is, the center of the lens is thinner than the outer edges.
What if your lens of your eyes are a bit too strong and your eyeball is a bit too long?
myopic or nearsighted.
What lens could correct the image formed of a nearsighted person?
concave lenses are prescribed by doctors
What kind of lens is a converging lens?
Convex lenses, also known as plus powered lenses, do cause light to converge. This type of lens is used on a Hyperopic (farsighted) patient. Concave lenses cause light to diverge and are used on Myopic (nearsighted) patients.
Is it true that The lens of a nearsighted person forms a sharp image of a distant object in a position in front of the retina instead of on the retina?
Por supuesto!
What part of speech is the word nearsighted?
Nearsighted is an adjective.
When a person is far sided do the need a concave lens or convex lens?
A person who is farsighted needs a converging lens, which is a convex lens, to help focus light properly onto the retina. This type of lens helps to converge incoming light rays so that distant objects can be seen more clearly.
Why does nearsighted need glasses?
in order to clearly see farther away
What type of lens is used to correct nearsighted vision?
Using concave lens the short sight problem could be rectified. Near sighted person cannot see the things far away. He can see things only so near to his eyes. The ray coming from the far object would form an image just before retina since the eye ball is elongated horizontally. So to make the image to move backward and fall on the retina, a concave lens is used to diverge the ray and finally the image would fall on the retina. Thus the remedy is possible with concave lens.
Is there any reason why glasses with the correct lens can't improve reading?
if you are nearsighted, it's because you are reading something that you don't need glasses to see. try to take your glasses off when you read, because if you don't it will strain your eyes horribly.
Which lens is the type of lens that is used in hand lens?
The type of lense is a convex lense
What type of eyeglasses will a patient need after cataract surgery?
A replacement lens is usually inserted at the time of the surgery.
