The Science
Three pages on the science behind your lenses, written to be quotable and graded claim by claim — including where the honest grade costs us a sale. Every significant claim carries an evidence mark, and the research pages end with their references.
- Established
- Replicated across decades of research; no serious scientific dispute.
- Supported
- Real evidence exists, but it is partial, modest, or context-dependent.
- Unproven
- Widely claimed in marketing; not demonstrated by good research. We say so.

Counted from the marks on the pages themselves, not graded again here. The unproven marks are the ones worth reading first: they are where the evidence does not support a claim we would benefit from.
