Which is better UV400 or uv420
Sunglasses with UV 400 protection are better than those with regular "100% UV protection." The are many definitions of ultraviolet, with different dividing lines. In many areas of biochemistry, 420 nm is the dividing line between visible light and UV. In other applications 380 nm is the dividing line.
