Final answer:
Dioptric demand is the inverse of the reading distance in meters and is independent of the actual bifocal addition power.
Step-by-step explanation:
The statement is true. Dioptric demand is the inverse of reading distance in meters, and it is indeed independent of the actual bifocal addition power. Dioptric demand refers to the power of a lens needed to focus light at a certain distance, and it is inversely proportional to the reading distance. This means that as the distance increases, the power of the lens required decreases, and vice versa.
