Are TheraSpecs polarized?
Our outdoor TheraSpecs are polarized to block the glare off of cars, water, and roads.
While this kind of glare protection works great outdoors, we don't use polarization on our indoor lenses for two big reasons:
(1) polarization can make computers, TVs, and tablets difficult to read, and
(2) polarization makes glasses too dark for comfortable indoor use, leading to chronic dark adaptation.
We only recommend polarization for sunglasses – that's why outdoor TheraSpecs are much darker and perfect for blocking bright sunlight!
