Shamir Optical Industry's first technological breakthrough, Eye-Point
Technology is a radical departure from conventional eyeglass lens analysis
tools. Ensuring an accurate design and analysis, it enables the development
and manufacturing of sophisticated, tailor-made progressive lenses.
The key element behind Shamir's Eye-Point Technology is a dedicated
ray-tracing program written by Shamir scientists. Combining lens surface
topography data with a highly advanced mathematical algorithm, this
sophisticated technology calculates the optical performance of thousands
of locations covering the lens surface, taking into account the following
parameters:
 - lens index refraction
- lens prescription
- lens center thickness
- distance from the eye to the back vertex of the lens
- distance from the lens to the object
- object’s angular position in the eye’s field of vision
- pantoscopic tilt of the frame
- pupil distance
- thickness reduction prism, and more.
