Where these two actually differ
- We flag Coating delamination and wear, Heavy metals in coating pigments or binders, Fluorine-containing polymers in coating binder (PFAS risk) and Biofilm or fungal growth on lens surface on the Haida and not on the B+W.
- The B+W is Optical glass lens with multi-coated optical surfaces where the Haida is Optical glass with multicoated UV filter, which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the B+W is the one to buy.
- We are less certain about the Haida grade, at 35% confidence against 82%, because it discloses less.
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 →
