Lenticular Option
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.

-Standard Lenticular
-Lenticular Plus with stronger reducing performance(Only this is available now)
-Adjust the lenticularization process to the frame shape(FSL)
• Optical Area
-Circular
-Circular
-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)
-Circular shape, centered in the fitting point. Smaller diameter can by specified to achieve thinner lens.
-Frame Shape adjusts the lenticularization process to the frame shape, which needs real and precise frame shape data, and the zone with improved thickness would be defined by a halo with a depth of 5 mm inside the frame shape in the temporal side.
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
