DescriptionOne family of Prospek blue light glasses, with the right lens for every hour of your day. Work & Office styles - Wayfarer, Cat Eyes, Aura, Era, Carbon, Velari, Shadow, Dynamic and Pro - use our near-clear lens that filters most of the strongest blue light from monitors, phones and tablets with low color distortion: ideal for the office, studying and everyday screen time. Gaming styles Destiny, Orion and Peak keep colors crisp for long sessions. For the evening, ULTIMATE (Work Late) steps up to a yellow lens that blocks 98% of blue light (400-500nm) - including the 460-480nm band that suppresses your natural evening melatonin - while still passing about 65% of visible light so you can keep working, and for the wind-down before bed, SOLARIS and FLARE (Pre-Sleep) use warm orange lenses that block 99.9 % of blue light across the full blue range (400-500nm) to support your body's natural wind-down - expect a visibly warm tint; that is the lens working. Every frame is ultra-light with 8 advanced lens coatings including anti-glare and smudge resistance, fits men and women, and arrives gift-ready with a hard case and a microfiber cleaning cloth. Day, evening or night - pick your frame, pick your hour, and make screen time comfortable with Prospek.
