Convex lenses cause the focal point to appear behind the lens (positive convergence). In myopia, the focal point lies somewhere between the lens and the retina, it needs to converge at a point farther than it is converging, this is why a convex lens is used, to push the focal point back so it will hit the retina.
A concave lens would do the opposite for hyperopia (the focal point appears behind the retina), it will adjust the focal point to lie more anteriorly and land on the retina.

What lens can correct a myopia?
Diverging Lens are use (reading glasses) to help correct the problem of myopia helping fix the focus which causes items far away to seem fuzy and blurry.
What do convex and concave lens do?
A convex lens converges light rays to a focal point, used to correct hyperopia (farsightedness) or create magnification in optical devices. A concave lens diverges light rays, used to correct myopia (nearsightedness) or reduce image size in optical systems.
How are concave lens and convex lens different?
Concave lenses are thinner in the middle and thicker at the edges, causing light rays passing through them to diverge. This type of lens is used to correct nearsightedness or myopia. Convex lenses are thicker in the middle and thinner at the edges, causing light rays passing through them to converge. These lenses are used to correct farsightedness or hyperopia.
What is convexo-concave lens?
A convexo-concave lens is a lens that has one side convex (outward bulging) and the other side concave (inward curving). This type of lens can be used to correct myopia (nearsightedness) by diverging light rays entering the eye.
What lens is used in vehicles is it convex or concave?
convex.
What type of lens would be needed to correct myopia concave or convex?
It would be concave lens. This is because it diverges the light before it enters the eye.
What lens is used in pair of binoculars?
A convex lens.
What type of lens is used in a hand lens?
double convex
Which lens is the type of lens that is used in hand lens?
The type of lense is a convex lense
Which lens system used in a microscope?
convex
Is a convex lens used as magnifying glass?
Yes, a convex lens can be used as a magnifying glass as it converges light rays to form an enlarged and upright image of an object placed closer to the lens. The magnification produced by a convex lens depends on its focal length and the distance between the lens and the object.
What kind of lens does a projector use?
projector have concave or convex
