Dioptres (D/dpt./PWR)
look for the figure on your prescription written as the 'dioptre sphere'. Beware of a + or - (minus = is replaced).
+ dioptres with problems with near vision (far-sightedness).
- dioptres with distant vision problems (near-sightedness).
Curvature (BC)
a parameter that provides the highest comfort while wearing lenses, i.e. how well the lens attach to your eye
Diameter (DIA)
This is the diameter (or size) of lens. If you have some lenses with a specific diameter that suit you then stay with them. It is not such an important parameter, but a different diameter size would be a gamble.
Cylinder (CYL)
an indication of negative values, which make any correction for the curvature of the cornea
Cylinder Axis (AX)
a value in the range 0° - 180°
Addition (ADD)
Indicates the difference between both your myopia and your hyperopia in dioptres
