Shamir Piccolo® is the most advanced soft, short
corridor progressive lens on the market. Ideal for
fashionably small frames, it is designed for eyeglass
wearers who don't want to compromise on style and
quality. Based on Shamir's advanced EyePoint
Technology®, Shamir Piccolo has an exceptionally wide
reading zone and far vision zone.
While fashion trends create a demand
for short corridor progressive lenses, there will always
continue to be a need for stable and comfortable vision.
Designing a progressive lens is a mathematical procedure
that involves managing optical errors to create optimal
fields of vision. The best PAL designs are those that
manage all optical variables and excess cylinders to
create a lens with adequate, clear fields of vision and
are easy to wear.
Therefore, when designing a short corridor lens, optical
engineers must take into account all optical variables,
while delivering a lens with a short corridor.
To provide a short corridor, the lens
designer may choose to manage unwanted astigmatism
across the lens by either spreading it over a larger
area in the lens (figure A) or by increasing the density
in limited areas (figure B).
