Lenticular Option

Advantages

 

Available for all IOT designs

Power distribution, personalization and lifestyle are essential factors to be weighed up, and also final thickness (center and edge) is a very important aspect to be considered. IOT offers a unique additional option available for any design included in this catalogue, the Lenticularization.

What is lenticularization?

Lenticularization is a process developed to minimize the thickness and weight of lenses. The user defines an optimal region around the fitting cross (Optical area); outside this region the Lenticularization reduces the thickness with a gradual change in curvature, giving as a result a thinner lens in the edge for minus lenses and thinner in the center for plus lenses.

Optical area

Optical area is a zone where the optical quality is optimum. Lenticular effect saves this area for optical vision and modifies the curvature of the lens outside the saved zone to reduce thickness. The relationship between the diameter selected and obtained result is simple: The smaller the optical area is, the more the thickness can be improved.

Diameters of lenticularization

To define the size of the Optical Area, there are several diameters available by default: 35, 40, 45 and 50mm. The IOT LDS, can also select any diameter required by the laboratory. Besides the circular shape, the optical area can be elliptical or adjusted to the frame shape.

Lenticular Types

MINUS LENSPLUS LENS

Lenticular
This type of lenticular is the strongest one; it makes a jump in power in the boundary from the optical to the lenticular area obtaining a thickness reduction. The lenticular zone is seen as a portion of the lens with different power and the boundary can be seen clearly.

Lenticular Parallel to
the External Surface (PES)

This type of lenticular links the backside in the optical area with a surface of the same curve as the front side. This enables a more efficient polishing process and, at the same time, achieves a high thickness reduction. The lenticular zone is seen as a section of the lens with different power, the boundary is wide and can be seen clearly.

Lenticular Frame Shape

It is possible to input the frame shape data in the IOT LDS. For calculating a frame shape lenticular lens, the system applies the lenticularization in a region around the frame edge. This eliminates the need to select an optical bowl diameter for lenticularization, providing thickness reduction adapted for every frame.

Halo width

The halo width comes predefined by the software in 5mm. Nevertheless the lab can modify it. Halo width and final edge thickness of the lens are directly related.

The wider the halo, the thinner the lens will be, but it will reduce the optimum visual region.
