PossibleOptical coating degradation and microabrasion
Where these two actually differ
- We flag Optical coating degradation and microabrasion on the Sigma and not on the B+W.
- The B+W is Optical glass lens with multi-coated optical surfaces where the Sigma is UV-absorbing optical glass or mineral coating, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
