OUR VERDICT
TrueDark

Best for: A Bulletproof/biohacking podcast listener who specifically wants the Twilight nighttime lens tier and is comfortable paying premium pricing for a named tier system.

View lens tiers at TrueDark
Spektrum

Best for: A biohacker who wants the multi-tier lens-shopping experience of Ra Optics, BON CHARGE, or TrueDark, but at a meaningfully lower price — Spektrum's lenses run roughly $45–50 versus $119 and up for those three brands.
