Noun:

ডিত্তপ্তর,

diopters's Usage Examples:

mostly used by people with advanced presbyopia who have been prescribed 2 diopters or more of reading addition.

measured as a ratio of convergence, measured in prism diopters, to accommodation, measured in diopters of near demand.

00 diopters of myopia and 5% have at least −5.

00 diopters.

50 diopters) has been.

Generally a difference in power of two diopters or more is the accepted threshold to label the condition anisometropia.

Of this power, the cornea provides roughly 40 diopters, and the crystalline lens 20 diopters.

particularly using circular graduations as on astrolabes, were also called diopters.

Every corrective lens prescription includes a spherical correction in diopters.

50 diopters) are considered to be diagnostic of disorders involving accommodative excess.

Sometimes far point is given in diopters, the inverse of the distance in meters (see Simple myopia).

For example, to change refraction by 4 diopters with an optical zone of 3 mm would require ablation of 12 μm.

50 diopters.

would have a near point of 1 11   cm = 9   diopters {\displaystyle {\frac {1}{11\ {\text{cm}}}}=9\ {\text{diopters}}} .

About 1 mm decrease in axial length cause 3 diopters of hypermetropia.

00 diopters of myopia and a maximum of 1.

75 diopters of astigmatism.

near- and far-sighted, they are not recommended for people with over 6 diopters of myopia.

diopters's Meaning':

a unit of measurement of the refractive power of a lens which is equal to the reciprocal of the focal length measured in meters; used by oculists

Synonyms:

unit of measurement; unit; dioptre;
