The Keiichi Standard Gray performance eyewear is the result of a two-year technical development process combining New York City athlete testing with Japanese precision engineering. The frames feature adjustable nose pads and temple tips with a grade 2 titanium core for a secure, customized fit. D+ therapeutic-grade lenses are constructed from shatterproof polycarbonate with interior anti-reflective, oleophobic, and anti-fog coatings that repel water and oil while providing comprehensive eye protection. The G15 lens blocks 100% of UVA and UVB radiation, transmitting 18.02% of visible light and 7.21% of blue light.
