Question

Options

• Reflects light away from the eye

• Absorbs excess light entering the eye

• Diverges light before it enters the eye

• Converges light before it enters the eye

Answer 1

A concave lens is used in spectacles for myopia because it diverges light before it enters the eye. In contrast, a convex lens is used in magnifying glasses, cameras, microscopes, and the human eye because it can converge light and form clear images.
