Justin Gaethje’s vision

Gaethje used to wear glasses regularly when he was the WSOF (PFL) champion.
I haven’t seen him wear them since he came to UFC.
Obviously he is or was nearsighted and I wonder how he could fight with blurred vision.
Is this a potential weakness that could be exploited by opponents?

He probably got surgery but I recall that too and wouldn’t be surprised after the gross negligence the Commissions have shown by sanctioning a 1 eyed Bisping that anyone with a junior high school education can pass their exams.
