Understanding Vision Defects
Myopia (Nearsightedness)
Light focuses in front of the retina. Corrected with concave (diverging) lenses with negative power.
Prescription Range: -0.25D to -10.00D
Hyperopia (Farsightedness)
Light focuses behind the retina. Corrected with convex (converging) lenses with positive power.
Prescription Range: +0.25D to +6.00D
Lens Power Formula
P = 1/f where P is power in diopters (D) and f is focal length in meters.
