we need convex lens in eyes as convex lens bulges out and thus focuses the outside light rays at a particular point in our eye, so then only we are able to see.

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.


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.


Do microscopes use concave or convex lenses?

Microscopes primarily use convex lenses. Convex lenses converge light rays to create a magnified image. There are also compound microscopes that incorporate both convex and concave lenses to enhance the quality of the image.


Which lens is used in projector?

since you need to show the image on a big screen so you require a diverging lens i.e. a concave lens

Does a camera use a diverging lens?

All cameras have converging lenses instead of diverging because they need a real image and not a virtual one to capture a photo.


Does a convex lens help you if you are farsighted?

Yes, a convex lens can help correct farsightedness by converging light rays to focus on the retina, improving close-up vision. The lens bends light towards the center, allowing the eye to focus properly and see objects up close more clearly.


What are lenses that make objects look larger?

You need a convex lens to magnify an image.


A transparent object that refracts light to form an image is called what?

You are thinking of a lens. If it is to form an image you need a convex lens, also called a converging lens.


What kind of lenses would a farsighted person need to correct their vision?

Hyperopic, plus powered, or convex lenses.


How do concave lenses and convex lenses help improve vision?

If you are farsighted, meaning that you can see far but you can't see objects close up, that means your eye is too short in terms of the distance of your retina to your lens. The image focuses behind the retina, so it becomes blurry. When you add a convex lens, it will help bend the light more and converge the light rays onto the retina, so you will see the image clearly. If you are nearsighted, your retina is farther away from your lens, so the image is focusing in front of your retina, so you can't see distant objects. That's when you need a concave lens. Concave lens will diverge the light rays onto the retina.


Does someone who has myopic need concave or convex lenses?

A person with myopia (nearsightedness) needs concave lenses to correct their vision. Concave lenses diverge light before it enters the eye, helping to focus the image correctly on the retina and improve vision for nearsighted individuals.
