About CLIFF
CLIFF is a US-registered lens brand.
Our made-to-order prescription lenses are freeform-surfaced, engraved, and fitted only through qualified eye care professionals.
We publish what each design does and where the evidence for it stops — the science pages grade every claim, including the ones where the honest grade costs us a sale.

How the evidence is graded
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.
What every lens is covered by
Every CLIFF lens leaves the laboratory tested and covered. Four commitments, on every pair.
