Where these two actually differ

  • We flag Heavy metals in optical coatings (antimony, cerium, lead), Glass dust from breakage and Fluorinated compounds in coatings (fluoropolymers, PTFE analogues) on the Promaster and not on the B+W.
  • The Promaster is Optical glass with protective coatings where the B+W is Optical glass lens with multi-coated optical surfaces, 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 Promaster grade, at 55% 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 →
