Study group discussion: Myopia and power mnemonic

Myopia (short sightedness) mnemonic, "Cave May Be Long"

CAVE - We use conCAVE lens
MaY - in MYopia
BE - BEfore image is formed before retina
LONG - eyeball eLONGate

When eye become Myopic it is acting as converging lens (+) convex lens (bend the rays coming from object the rays towards centre) more power more convergence more bending so we use diverging lens which is a concave lens to correct or to neutralise the bending or converging.

Concave lens negative (-ve) power.
