I'm bias due to my profession, and regularly get attacked for this point on the Internet by people who think they know better, but glasses.
My eyes aren't even bad, but when I wear them, holy shit is there a difference between the high tech new stuff and basic lenses.
Anyone that tells you online glasses are just as good has never had a 600$ pair from a real (not chain) optical. Anyone who says they have got ripped off by Pearl vision or LensCrafters.
I mean, I want to scream acab too, but there's not even a cause of death yet. Let's try to stay credible.
