A couple years ago, no tools π . I was commuting between home and campus just a mile away, so if something went wrong I'd just lock the bike and come for it later.
Nowadays, just a few to do an inner tube & chain replacement, and some other small bits that might come in handy.
2 spanners (one adjustable)
Backup lights & head torch
Tyre levers & adhesive puncture patches
Mini track-style pump
Screwdriver for the chain enclosure
Pliers for the rollerbrakes and internal hub gear cables

I've found the head torch to be surprisingly helpful... Had a puncture in the dark once, and without that I would have been there a while lol
I wear cycling glasses all the time when riding, for the same reason as @[email protected] to keep the bugs out. They also prevents my eyes from tearing up during the winter
Used to wear safety glasses, but jumped to cycling ones after a while because people would just uncomfortably stare π
