Concave lens is used to correct Myopia (Nearsightedness).
A concave lens is used for the prevention of Myopia (Nearsightedness). A concave lens is a lens that is a divergent lens. It spreads the rays on the eye, which makes the object look clear. A surface of the concave lens is tilted inward and compared to its edge, this lens is diluted in the center. This lens is used to make glasses and binoculars.
A concave lens is also used for the prevention of myopia. Myopia is such an eye disorder, due to which distant objects appear blurred. Due to this vision, the reflection of the distant object falls in front of it instead of falling directly on the retina of the eye, which makes the object look blurred. Due to this vision, the distant object appears blurred and the nearby objects appear normal.
