Which is the best sports sunglasses lens material ...
2021-9-27u2002·u2002I want to say at the start that both lenses (PC and NXT) are ideal for sports sunglasses and will do the job. For me it is a 'no brainer' that you need good impact resistance for sports sunglasses. Polycarbonate and Trivex NXT® are up to 10 times more impact-resistant than glass, plastic, TAC or CR39 lenses.
