2-4 Introduction to Cylindrical Lenses

Cylindrical lenses are introduced, with attention to the definition of lens power, and the idea that light is focused to a line instead of a point.

What will happen if the light is coming from the plain side beyond 2f or infinity. will it diverge or converge

how to make square shape light by cylinder lens or two lens ?thanks is that possible ,by led SMD

[@electric1534]

Brilliant explanation

[@Zeugenschutz]

If i have a Rx 2.25 -0.25 x 90 does that mean axis 90 i have power 2.25, axis 135 i have 2.125 axis 180 i have 2.00? so if my Rx went from 2.00 (no cyl) to 2.25 -0.25 x 90 i would only have a 0.25 change in Rx?
