LENS CURVATURE
The base curvature represents the radius of the sphere measured from the back of the lens. We offer models with a base 6 lens curvature but with the additional KINETIC SYSTEM technology it is possible to mount base 4 prescription lenses on the alter stealth frame.
BASE LENS 4*
*we do not currently supply prescription lenses but if you purchase the additional “kinetic system” technology during the customization of your glasses we will automatically provide you with the technical data of the base 4 prescription lens so that your trusted optician can produce it for you
BASE LENS 6
The base 6 lens used for our Altera Stealth glasses has a slightly greater curvature than base 4 prescription lenses.
