Which lens can we use to correct long sightedness in the human eye?


We can use convex lenses which are thinner at the edge than at the center to correct long sight.Convex lenses are used to bend light rays slightly inwards due to which the long sightedness will be corrected. The curvature, thickness and weight will be decided after analyzing the severity of the issue . After wearing a lens which is made according to prescription, the light rays will fall onto your retina that creates a clear image on focus..
