What are FL Sun TheraSpecs' visible light transmission (VLT)?

FL-Sun™ TheraSpecs are available in two different tint strengths: "Dark+" which filters 90% of light, and "Ultradark+" which filters 96% of light.

These dark, protective lenses are polarized to deflect glare, and have been designed to be worn outside to help with sunlight sensitivity.

Note: because they're so dark, FL-Sun Ultradark+ aren't legal for driving in most places
