Delta Photochromic Sunglasses

Alba Optics Delta Photochromic Sunglasses

Take your performance to the next level with the Alba Optics Delta Photochromic Sunglasses – the perfect blend of retro inspiration and modern engineering, built for road cyclists, gravel riders, and triathletes who demand precision and durability. Inspired by iconic styles from the 80s and 90s, the Delta combines timeless design with advanced materials like Tr90 – a nylon and carbon fibre blend that’s 20% lighter than conventional frames, yet tougher and more resilient under pressure. From climbing under a blazing sun or battling headwinds under rain-laden skies, the photochromic lens keeps your vision clear and your focus razor-sharp.

Lens Specifications:

VZUM™  F-Lens Photochromic Technology

The VZUM ™ F-LENS Photochromic technology is a photochromatic lens that adapts itself to the intensity of the light present in the environment. It automatically changes colour, shielding off harmful UV rays of any sort. Their temporary transformation takes place in a short period of time, gradual and independent of any atmospheric factors. The optical strain is reduced to a minimum and the lenses remain active even on a cloudy day.
