Problem 12CQ

Problem 12CQ

Prescriptions for vision correction are given in units called diopters (D). Determine the meaning of that unit. Obtain information (perhaps by calling an optometrist or performing an internet search) on the minimum uncertainty with which corrections in diopters are determined and the accuracy with which corrective lenses can be produced. Discuss the sources of uncertainties in both the prescription and accuracy in the manufacture of lenses.

Step 1 of 3

Diopters (D). Determine the meaning of that unit.

The concept of retinal light correction measurement was founded in 1872 by the French ophthalmologist Ferdinand Monoyer. He determined the term "diopter" to a lens with a focal length of one meter. A Diopter can be positively or negatively measured and generally determines the refractive power of a lens or its respective power. Mathematically, its equivalence is equal to the inverse of the focal length when measured in meters. Its value can be negative or positive. The positive value is given for convergent lenses while its negative value is given for divergent lenses.
