Seraphic Lucid Clear

Clear acetate, so the lens does the talking. The tint is the only color on your face.

Transparent acetate is the hardest finish to get right — every inclusion shows — which is why the Lucid Clear is cut from a single block and polished across more than sixty steps until the edges read like glass. On a clear frame the amber or red lens becomes the whole design, and most people find that easier to wear than a heavy black frame when they are already winding down. Same wayfarer geometry as the rest of the Seraphic line: 48-21-145 on a 140 mm front.

Two tints, two jobs

Amber through the evening. Red for the last hours before bed.

Amber lensEvening and all-day wear0.10% measured transmission at 450 nm, the melanopsin peak. Luminous transmittance 50.5%, Filter Category 1, rated for indoor and outdoor use.
Red lensThe last hours before bedZero measured transmission from 380 to 560 nm — blue and green removed entirely. Luminous transmittance 14.9%, Filter Category 3, indoor use only.

All figures are single-lens spectrophotometer measurements from our own laboratory reports for this lens, tested to EN ISO 12312-1, ANSI Z80.3 and AS/NZS 1067.1. Individual response varies.

Fit

Will the Seraphic fit you?

Check the three numbers printed inside the arm of a pair you already wear. A lens width between 46 and 50 mm puts you in range. The wide 21 mm bridge sits well on a flatter nose bridge, and at 40 mm the lens is shallow enough that it will not rest on your cheeks. Clear acetate shows skin tone through the rim, which tends to soften a strong jaw rather than frame it.
