FitLens is a frame finder for 155 mm+ faces: it returns your face width in millimetres and the frame front width that fits, instead of guessing from photos.
FitLens is a virtual fit tool, not a virtual try-on. It uses your phone camera and a credit card (85.6 mm) as a scale reference to return your temple-to-temple face width, your nose bridge width and your pupillary distance in millimetres — then tells you whether our 158 mm front width fits. No app, no account, about 20 seconds.
It measures face width, bridge width, pupillary distance and the front width that fits you. It does not render frames on your face, does not replace an eye test or prescription, and does not guess: outside 145–162 mm it says so.
A virtual try-on shows how frames look. FitLens shows whether they will actually fit a 155 mm+ face. Appearance is subjective; fit is a number in millimetres.
The camera frame is processed to extract measurements and is not kept as an identifiable profile. Only the resulting numbers persist, and only if you save or email your result.
