Volta Blue Light Blocking Glasses (Evening) - Sazerac with Amber Lens pairs architectural structure with science-backed lens technology. Designed with a bold, square silhouette, this oversized frame flatters wider face shapes while delivering a refined, confident aesthetic. Crafted from premium organic acetate and fitted with optical-grade lenses, Volta ensures crisp, distortion-free clarity throughout the day and into the evening.
The proprietary amber lenses filter up to 23x more impactful blue light than standard blue light lenses and have been associated with up to a 3x increase in melatonin levels when worn in the evening. Clinical testing also measured a 47% increase in cognition, while 9 out of 10 customers report relief from eye strain, headaches, or blurry vision.
