IN THICKNESS IMPROVEMENTS

What is lenticularization?

Lenticularization is a process developed to minimize the edge thickness of a lens
•The Lab defines an optimal region (Optical area); outside this region the software reduces the thickness with a gradual changing curvature/power, giving as a result a thinner lens in the edge for minus lenses and thinner in the center for plus lenses.

• Optical area is a zone where the optical quality is as high as possible

-Lenticular effectsaves this area.

-Outside this area to reduce thickness

• optics worse The smaller the optical area is, the most the thickness can be improved.

• Lenticular is a feature that can be added to every design

• Outside this area the lens has a very poor optics, but the thickness can be greatly improved.

• Optical Area

-Circular

-Elliptical

-Frame Shape

• The optical area can have the following shapes:
-Circular shape, centered in the fitting point. This parameter can be specified by design name (35,40,45&50)
-Ellipticalshape, centered in the fitting point. The smaller diameter can by specified . The difference between
radiuses can only be indicated by design name

- Frame Shape reduced along the temporalside. The length of reduction can be chosen by the design name, although 5mm is the typical default value.
- 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.

Lenticular Plus

- Higher thickness improvement.
- Less aesthetic because there is a strong transition between the optical area and lenticular area.
- The lenticular area is seen as a portion of the lens with different power. The boundary can be seen clearly.

Recommendations

• Which is the best diameter?

- High Prescriptions ± 6,00D
· small ø ( 32-40 )
· ↑ Rx → ↓ ø

- Sport frames ( Hight HBOX )
·ø medium - hights ( >45 )
·Less visual field reduction
