Yeah it’s been known for years he can’t see shit. But he is too vain to wear glasses in public. He does wear them in private, there are some pics out there. Which is pretty normal for someone his age.

This is part of why his speeches are always so weird and fucked up. He misreads because he needs his glasses and then makes shit up to try and cover for it. The speech prepared is usually evil and fucked up in different ways, but at least coherent. Then when Trump tries to read them a lot of nonsense comes out.
