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.
If a person is farsighted do they need concave or convex lenses?
A person who is farsighted would need convex lenses to correct their vision. Convex lenses help to converge light rays, bringing the focus point forward onto the retina, which helps in correcting farsightedness.
What lens does farsighted people need?
Farsighted people typically require convex lenses to help them see objects up close more clearly. These lenses are thicker in the center than at the edges, helping to bring close-up objects into focus for those with farsightedness. An eye examination by an optometrist or ophthalmologist can determine the specific lens prescription needed.
What the differences between convex lens and concave lens?
A convex lens is thicker at the center and thinner at the edges, causing light rays to converge and focus at a point (real image). A concave lens is thinner at the center and thicker at the edges, causing light rays to diverge and appear to come from a virtual focal point. Convex lenses are used to magnify and focus light, while concave lenses are used to spread out light rays.
What is another name for a convex lens?
Concave and convex can refer the types of lenses used to treat refractive errors in the eyes. Concave is another word for myopic lens and convex is another name for a hyperopic lens also known as nearsighted and farsighted respectively

Where does a convex lens make an image fall for a farsighted person A beyond the retina of the eye B before the retina of the eye C on the retina of the eye?
A farsighted person (hyperopic) has difficulty seeing nearby objects because the image is formed behind the retina. A convex lens is used to converge light rays so that the image falls on the retina, allowing clear vision. So, for a farsighted person, the convex lens corrects vision by focusing the image on the retina.
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.

Should a farsighted person use a concave or convex?
You must use convex lenses because in farsighted person the image is formed at the back of retina so it must be move forward to make it exactly in the retina so convex converges so it will be forwarded.
Why is convex lens used for correcting farsightedness?
A convex lens is used to correct farsightedness (hyperopia) because it converges light rays, allowing them to focus properly on the retina. Farsighted individuals have a shorter eyeball or flatter cornea, causing light to focus behind the retina. The convex lens helps refract the light so that it focuses correctly on the retina, improving vision for near objects.
If i am farsighted what lenses do i need?
Convex lensesConverging lenses
What is double convex?
with the help of convex lens we are able to converge the beam of rays to the fix point.
What kind of lens does a projector use?
projector have concave or convex
