Riviera Tortoise Brown
A soft cat eye in tortoise, small enough to disappear into an evening.
Riviera is the smallest eye size in this group at 50 mm, drawn as an oval with a lifted outer corner rather than a hard cat eye. The 19 mm bridge is wide for that eye size, which pushes the lenses slightly apart and keeps the shape from crowding the nose. Front width is 135 mm and lens height 33 mm, so the whole frame stays compact and light on the face. Tortoise patterning breaks up the rim visually, which is why a small frame in this color tends to read as jewelry rather than eyewear.
Two tints, two jobs
Amber to unwind, red to finish
Amber lensEarly evening, indoors or outThe curve starts near zero, 0.10% at 450 nm, then lifts through 40.5% at 550 nm to 66.6% at 560 nm and 96.3% at 600 nm. Rated Filter Category 1 at 50.5% luminous transmittance, so it suits indoor and outdoor wear.
Red lensBedside readingFrom 380 to 560 nm measured transmission is zero, so blue and green are removed entirely. Only long wavelengths pass: 5.8% at 570 nm, 49.7% at 600 nm, 92.9% at 700 nm. 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 Riviera fit you?
Riviera is a medium frame at 135 mm across, but the 50 mm eye makes it the most compact shape here. The 19 mm bridge suits a wider or higher nose bridge and will feel roomy on a narrow one. Lens height of 33 mm is shallow, so the tinted field stays high on the face and well clear of the cheek. Temples measure 145 mm. If you prefer a frame that covers more of your downward view, choose a deeper lens.
