Answer Details

Spectacles with convex lenses correct long-sightedness by converging the light rays before they enter the eye. Long-sightedness, or hyperopia, is a condition where the eye is too short or the cornea is too flat, causing light to focus behind the retina instead of on it. Convex lenses are thicker in the center than at the edges, causing them to converge incoming light rays towards a focal point. By placing a convex lens in front of a long-sighted eye, the lens will converge the incoming light rays and bring the focal point forward, allowing the image to be focused on the retina and improving vision clarity.
