How it works

Compare published intervals

Enter a selected VLT window and actual lens specifications. An overlap includes both endpoints. Fixed lenses use one value repeated at both endpoints; photochromic specifications retain the published range.

Keep optical and fit questions separate

A range overlap is not a prediction of instantaneous tint, transition speed, optical contrast, UV protection or fit. No altitude-derived correction or universal lens-color recommendation is made.

FAQ

Use the exact manufacturer guidance for the intended light conditions and record your reasoning. Lower VLT transmits less visible light. Altitude alone does not determine the required window.

No. Overlap can be only one endpoint, and the published range does not predict tint at a particular moment. Review transition specifications, conditions, optical performance and fit separately.
