Where the cat-eye shape appears

Gentle Monster’s Sage 01 page specifies a black acetate frame, black lenses and a cat-eye shape, and labels the model 2026 Collection. The KUANGTU record archive-1094-sage instead uses the broad shape category Other. That generic catalogue category does not capture the more specific outline visible in its photograph.

In the supplier front view, the outer ends sit higher than the inner corners near the bridge. The lens opening has a straighter upper section and angled sides, with rounded transitions rather than a sharp triangular tip. Describing those features is more informative than assuming every cat-eye frame has the same exaggerated upsweep.

When comparing this reference with another black frame, align the bridges in the photographs and look at where the outer corners finish. That reveals the change in line more clearly than comparing overall darkness or a brand label.

Why front width and lens height add useful information

The official Sage 01 dimensions are 55.3 mm lens width, 20 mm bridge and 146.9 mm temple length, plus 148.9 mm frame-front width and 36.1 mm lens height. The complete front width includes parts of the frame that a lens-width number does not describe.

For that official version, twice the lens width plus the bridge is 130.6 mm. The stated front width is 18.3 mm greater. That difference illustrates how the outer frame and hinge area affect the overall span; the 55.3 mm lens number alone cannot tell a buyer the total width.

The 36.1 mm lens height also helps distinguish the relatively shallow opening from a taller cat-eye design. These are published specifications, not our measurements or a prediction of how the frame will sit on a particular face.

Keep the supplier size code separate

The supplier record gives 55 / 20 / 147 mm. Compared with the official source, the bridge value is the same, the listed lens width is 0.3 mm smaller and the temple value is 0.1 mm longer. The numbers are close, but their similarity does not prove that the catalogue record is the same Sage 01 version.

Do not automatically describe those differences as rounding: the supplier record does not explain its measurement method. For a fit-sensitive order, ask for the actual front width and lens height as well as a photograph of the inside-temple code. A sample fitting remains separate from comparing catalogue numbers.

Build a brief around the outline you want to preserve

For archive-1094-sage, a useful brief identifies the black reference photograph, the raised outer corners and the desired lens appearance. Add quantity and destination, then request front and side photographs of the available version. If a substitute is proposed, compare the outer-corner lift and depth of the lens opening before treating it as equivalent.

The catalogue says Tinted lens; it does not independently establish the official version’s material or lens performance. Use the linked product page to save this exact reference and request confirmation of any specification that matters to the order.
