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).
