There's little buttons on the side you can press to pull the shroud out further away so you can just wear your glasses inside the headset. My brother wears glasses and hasn't messed up my Q3 when he's used it so I assume it's not so close there's a huge risk to the lenses.
But you also can get prescription lenses for it. Or switch to contacts if possible ๐คทโโ๏ธ
