HUUB Aphotic Black & Red: photochromatic goggles for changing light

The HUUB Aphotic Swim Goggle in Black & Red is built around photochromatic lenses. Rather than keeping a fixed tint throughout a session, the lenses respond to changing light, making this a relevant option for triathletes training outdoors.

Key specifications

• Photochromatic lenses that darken and lighten as conditions change.
• Silicone and TPR construction around the face.
• Designed for indoor and outdoor swimming.
• Black & Red version identified by HUUB as A2-AGBR.

A lens that responds during the swim

HUUB describes a transition from clear to dark in 160 seconds, with the tint fading back as UV light diminishes. That figure is a manufacturer claim, rather than a response time independently measured by Triathlon Insight. It also means swimmers should not expect an instantaneous change.

For triathletes

For early starts and courses that turn towards and away from the sun, changing light is a useful consideration alongside fit. Check the seal and practise spotting course markers during training. This article covers the Black & Red photochromatic model; other Aphotic colours and lens versions should be checked separately.
