100% UV400 protection UV400 protective coating can block 100% of harmful UVA and UVB rays. Polarized lenses can reduce glare from roads, waterways, snow and other horizontal surfaces.
Photochromic reading glasses Photochromic reading glasses are clear indoors or at night, and will automatically darken into sunglasses when exposed to ultraviolet rays. The lens will start to clear immediately after being away from ultraviolet radiation, and will be significantly lighter, and most of it will be cleared within a few minutes. They absorb ultraviolet light, otherwise it will harm your eyes.
Restore true colors, eliminate reflected light and stray light, and perfectly protect the eyes.
Comfort and durability The glasses are composed of ultra-light pure titanium frame, soft silicone nose pads and strong metal hinges. All details ensure perfect performance. The soft silicone nose pad can adapt to different nose shapes.
