Recently, a pair of polarizing sunglasses was submitted to us to build. I was told that polarizing lenses are not spotted in the same way as regular lenses, and that if there was even a minor error in the axis of the mounted lenses, the result would be to nullify their polarization effect.
Can someone fill me in on these creatures?
The only reference work currently available to me is Clifford Brooks "Essentials for Ophthalmic Lens Work" and it does not mention polarizing lenses.
