Are TheraSpecs polarized?
Our FL-Sun TheraSpecs sunglasses are polarized to block the glare from things like cars, water, and roads.
While this kind of glare protection works great outdoors, we don't use polarization on our other lens options (FL-Pro, FL-Blend, Flex, Z-Blue, Sleep, and Contrast HEV) for two big reasons:
- polarization can make computers, TVs, and tablets difficult to read, and
- polarization makes glasses too dark for comfortable indoor use, which may lead to chronic dark adaptation.
We only recommend polarization for sunglasses – that's why our FL-Sun TheraSpecs are much darker and perfect for blocking bright sunlight!
