Sleepaxa Mosaic Golden Glass FL-41 Migraine & Light Sensitivity Glasses

Mosaic Golden Glass

A true round in a honeyed golden glass acetate, and the smallest front in the Heritage Series.

Round frames live or die on proportion, and the Mosaic keeps its at 47 mm eye against a 134 mm front, the narrowest measurement offered, so the circles stay circles instead of stretching into ovals. Golden Glass is a translucent amber-gold, cut from Italian cellulose acetate and polished over more than sixty steps until the material reads like glass at the rim. The 43 mm depth is generous for a frame this small, which means the tinted lens still covers the field rather than floating in the middle of it. Built for small and narrow faces that most migraine glasses simply swim on.

The tint, stated as measurements

• 7.9% measured transmission at 420 nm and 13.8% at 450 nm - the blue band is attenuated across its width rather than cut
• 12.6% at 520 nm - the green band is attenuated in the same pass
• 44.2% at 570 nm rising to 100% above 670 nm - the rose band is deliberately preserved
• Luminous transmittance 41.1%, Filter Category 2
• 100% UV protection (UV400)

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.

Will the Mosaic Golden Glass fit you?

The three numbers inside your current arm are eye, bridge and temple in millimeters. Mosaic is 47-20-145. Its 134 mm front is the narrowest option we list, made for faces around 128 to 136 mm across; if your last frame was 140 mm or wider, this will grip. The 20 mm bridge is wide for such a small eye, which lifts the round lenses apart and keeps them from crowding the nose. Round shapes suit angular and square jawlines particularly well.
