brytningsstyrka
Brytningsstyrka, often translated as refractive power or dioptric power, is a measure of how strongly a lens or a curved optical surface converges or diverges light. It is inversely proportional to the focal length of the lens or optical system. The unit of brytningsstyrka is the diopter (D).
A lens with a brytningsstyrka of +1.00 D has a focal length of 1 meter. A lens
The formula relating brytningsstyrka (P) to focal length (f) is P = 1/f, where 'f' must be in
In optometry and ophthalmology, brytningsstyrka is crucial for prescribing corrective lenses for vision problems like myopia
