Product Description
1.523 PGX Flat top photochromic Finished.

1) The most popular fused bifocal today has a D-shaped near segment rotated 90 degrees so that the flat part of the "D" is facing up.
For this reason, D-seg bifocals also are called "flat-top" (FT) or "straight-top" (ST) bifocals.

2) This is a D segment bifocal lens. It has the benefit that the optical centre of the near vision part of the lens i.e. the part of the reading
area which gives the very best vision, is situated at the top of the reading portion. Also the widest part of the reading area is just below
the dividing line, and is the part of the lens the wearer would use.

Outstanding Color Performance..
1.Fast speed of changing, from white to dark and vice versa.
2.Perfectly clear indoors and at night, adapting spontaneously to varying light conditions.
3.Very deep color after change, the deepest color can be up to 75~85%.
4.Excellent color consistency before and after change..
