Lens Technology: Blue light filtering, anti-glare, UV 400, and almost clear lens protects your eyes during extended digital screen time. By blocking the most harmful part of the blue light spectrum and allowing partial transmission of "good" blue light, Umizato glasses provide better sleep with regulated circadian rhythm and melatonin production.
My son absolutely loves these he does a lot of gaming and online socializing and he said he could tell a drastic change in his vision and headaches from using these glasses, Thank you Umizato
