Abstract
The invention provides methods for designing lenses useful for correcting astigmatism in which there is a progressive cylinder power. The lens of the invention permits the cylinder power to act under low luminance situations to a different extent than in higher luminance situations eliminating the need for extra toric minus power that may interefere near vision at mid range luminances while assisting distance vision at low luminance conditions.
