The first diffractive trifocal optic
The FineVision optic combines two diffractive structures that are adjusted to offer the +3.5 D addition for near vision and another +1.75 D addition for intermediate vision.
It is designed so as to reduce the loss of light energy resulting from any diffractive system.
This energy gain results in a significantly improved performance for intermediate vision while maintaining the performance for far and near vision.
Optimising far, near and intermediate vision
The FineVision optic has a diffractive anterior surface entirely convoluted. By varying the height of the diffractive step, the amount of light distributed to the near, intermediate and distant foci is adjusted according to the pupil aperture.
Promising visual results
The results obtained with the FineVision optic are promising and consistent with observations and laboratory tests with very satisfactory uncorrected visual acuity at all distances and an extended range of vision in all light conditions.
