UV400 is the American Standard for sunglass protection. UV400 will protect your eyes from both types of UV light that can affect the naked eye; UVB rays which cause sunburns and in conjunction with wind and snow can cause snow blindness; and UVA rays which are absorbed thru the lens of the naked eye. The protection of the lens is not dependent on the darkness of the lens, but rather the FILTERS, which are what shields your eyes from the UV light.
