1. The computer says NO!

2. High plus and minus lenses
 Super-Lenti Glass
 Super-Lenti HD
 Recre
 Bonding glass
 Double sided working Bi concave
– Sphere and Cylinder
– SV
– Bifocals

3. Compensated powers
 On wraps the powers will change due to
– Wrap angle
– Wearing distance
– Power

4.  Nortor HD SV in a 8 Base
 Full Rx required plus:-
– Optical Centres and heights
– Wrap Angle
– Tilt angle
– BVD trial and actual
– Pupil Diameter
– Lens Curve

5. Sportor optic design but with
reduced edge blend
Reduces both plus and
minus
Peripheral edge blend
45/50mm clear zone
Applied to all lens designs

6.  Segment on the rear
surface
 Blended to make it
invisible
 All Materials
 Adds to +4.00D

7.  Nortor and Ultor XXL free
form
 Effectively produces Up
to a 100mm uncut lens

8. High Prisms and Prism Control
 PUCK
 Slab off Traditional FT28

 65mm diameter
 Up to 20D of prism
 Any curve combination

10. Slab Off /On
 Removes unwanted differential vertical prism
 Minimum slab off 2D
– Less on freeform
 Maximum 10D dependent on blank
substance
 SV BIF PAL

11. Anisometropic Corrections
 Base up prism incorporated to relieve
anisometropic Rx’s
 One lens or split between the two

12. Yoked Prism
 Amount dependent on uncut substance

13. Iseikonic Lenses
 Magnification derived from substance and
curves
 Both Rx and Plano

14. Over Decentred D seg
 12mm inwards
decentration
 Amount of Prism
dependent on add

15. Franklin Split

 Glass Round segs
 Glass D Segs
– Zeiss Centre Prism Segment
 Franklin Split
 Presto
 Odd Segment sizes
 Over Decentred D seg
 Slab Off / On

18. Odd Size Segments
 Dependent on Add
– d1-d2= 2c(F1-F2)/A
– Larger segment induced more base down prism
 Cost effective
 1.5 index only Glass /Plastic

19. Glass Round Segs

25.  Bifocal with ULTOR
progressive (smart seg)
 Increases the Near
area in size and
working distance

26.  Remake of the popular
Essilor pilot

27. Occupational
 Versatile
