In glasses to further the focal length so it is able to be focused at the retina.
A concave mirror converges light rays to a focal point, while a concave lens diverges light rays away from a focal point. Concave mirrors are used for focusing light, such as in telescopes and makeup mirrors, while concave lenses are used for dispersing light, such as in correcting nearsightedness.
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.
A concave lens has a thinner middle than the edges. This causes light rays passing through the lens to diverge, which is why concave lenses are often used to correct vision problems like nearsightedness.
A concave lens is thinner at the center than at the edges and causes light rays to diverge. This lens is used for correcting short-sightedness. In contrast, a convex lens is thicker at the center than at the edges and causes light rays to converge. This lens is commonly used in magnifying glasses and camera lenses.
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.

A concave lens is a lens that is thinner at the center and thicker at the edges. It is used to correct myopia (nearsightedness) by diverging light rays before they enter the eye, thus helping to focus the image on the retina. Concave lenses are often used in glasses or contact lenses for people with nearsightedness.
CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.
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.

The ocular lens used for nearsightedness is known as a diverging lens. It is also known as a concave lens.

it spreads light rays apart,or it is used in a camera lens.
