Dioptres (D/dpt./PWR)
Power refers to the refractive power of the contact lens. Look for a plus (+) or minus (-) sign. Note that an equals sign (=) may be used in place of a minus sign.
Curvature (BC)
The base curve describes the curvature of the contact lens surface, i.e. how well the lens fits the shape of your eye.
Diameter (DIA)
The diameter is the width of the contact lens (measured in millimeters). It is not recommended to select a new diameter size without first consulting your optician. Diameter impacts the fit, comfort and functionality of your lenses.
Cylinder (CYL)
The cylinder measurement is used for the correction of astigmatism. It is a negative value that corrects curvature of the cornea.
Cylinder Axis (AX)
The cylinder axis measurement is used for the correction of astigmatism. The value ranges from 0° - 180° and determines the exact position of corneal curvature.
Addition (ADD)
Addition is the difference between the dioptric value for distance vision and the dioptric value for near vision. It indicates the magnifying power in multifocal lenses.

What is astigmatism?
Astigmatism is an aspherical refractive defect where the eye exhibits different refraction in two sections. Astigmatism may be regular (most frequent) or irregular. Read more about what is astigmatism.
The ground-breaking MoistureSeal technology uses the unique process of two-phase polymerization that offers unbeatable oxygen permeability and a low modulus which results in better flexibility. In combination with high water content, they guarantee all-day moisturizing and optimum wettability.
ULTRA contact lenses maintain 95% moisture for a full 16 hours and prevent the lens from the dryness that is often caused by less frequent blinking while using electronic devices. They bring advantages in all key areas and offer the best physical properties in their class. The constant moisture of the ULTRA contact lenses is the key condition for everlasting comfort during wear.
