3M seems superior! The odd thing is, I've read many recommendations for Huper Optik, although it offers only a 10-year warranty. There must be something better that Huper Optik has over 3M. Hearing about the problem with polarized eyewear is a let-down though. Formula One and Solar Gard provide lifetime warranties. How is 3M's warranty? If anyone knows, is it free of the polarized problem?
