Maybe they do and probably they don't; our human eyes are rotten judges of how well we can see. It's really easy (and very common) in headlighting to create a situation where we think/feel we have terrific seeing at night but in fact we have dangerously poor seeing, and vice versa.
Maybe they are and likely they aren't; there's an awful lot of crap on the market with phony/counterfeit DOT markings or other fraudulent claims of legality. What are they exactly? Brand, model, source...
