EXOR - Modern wrap-around safety lenses offer the user many advantages, but the curvature of a spherical lens also comes with drawbacks. On the edges of a curved lens, incoming rays of light are refracted more strongly than at the centre. This leads to a blurred focal point, causing spherical aberration. EXOR counteracts this. We recalculated the lens radii in such a way that an aspheric structure (parabolic profile) of the lens surface counteracts the refraction as described above much like opposing prisms. All light rays are combined in a clear focal point, making high precision mechanical tasks possible.
