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.

They need a concave lens

Does a convex lens help you if you are farsighted?
You need a type of lens that are called convex lens.
Do microscopes use concave or convex lenses?
They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use 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.
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.
If Jane is myopic. Will she need concave or convex lenses explain?
Concave. With myopia, the focal point of the eye is in front of the retina. Concave lenses increase the distance of the focal point so that it lies on the surface of the retina.
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.
