LENS FAQ
Questions about this lens
Are photochromic and polarized the same function?
No. Photochromic describes the tint response to UV exposure. Polarization helps reduce certain reflected glare.
Why does the lens darken less inside a vehicle?
Many vehicle windshields block a significant amount of UV light, which can limit photochromic activation.
Will the tint always reach the same darkness?
No. Tint depth and transition speed vary with UV intensity, temperature and environmental conditions.
