How do FL Sun TheraSpecs work?

FL-Sun™ will be your new favorite sunglasses lens and will take extra care of your eyes when you go outside. It uses the power of FL-41, with enhanced filtering from 480-520nm, and wraps it in a dark, polarized lens so you have maximum protection against bright sunlight and outdoor glare. FL-Sun is the perfect option when you’re on the go; add it to your outdoor light management plan if you have migraine and/or photophobia, or just make it your next awesome pair of everyday sunnies.
