Advanced Ray Tracing
Position of Wear Calculation Technology
A typical multifocal lens design is made assuming that light comes on the lens axis in the form of parallel lines
Therefore, images of the surface analysis of a typical multifocal lens design are as follows.
However, considering what the eye actually sees, it is obvious that light comes from different angles.
And in real use, the visual fields of the multifocal lens will be as follows.
Advanced Ray Tracing technology dramatically improves the performance of lenses in real use. The reason for this is that the oblique aberration that occurs in the gaze outside the optical center is almost completely eliminated by this technology.
​
Advanced Ray Tracing The refraction of the rays passing through thousands of different points on the lens is calculated by taking into account the cross view, and the multifocal surface is optimized against oblique errors.
In all lenses, the eye looks through the lens from different angles to see the objects around it.
The points used in Advanced Ray Tracing design analysis are as follows.
The structure of a typical multifocal lens optimized with Advanced Ray Tracing technology is as follows.
