Basically current gen has no issue with big enough text. Even a quite low res PSVR is good readable so i guess you were out of the sweetspot of the HMD or bad software or it was a very old HMD. Just try one of the newer:
If you wear glasses normally many headsets have enough space inside for it or maybe you don't even need your glasses (many people experienced that) or you can use lens inserts for some HMD's (but i don't know which one).
