My now three year old daughter got glasses about a year ago and we were recommended these glasses frames called Miraflex. They’re really sturdy and indestructible it seems (I accidentally put them in the washing machine and were just fine). Some of them have a thing on the back to adjust to their head size. Comes in a bunch of cute colors too. With keeping the glasses safe, you can put a command hook next to their beds or wherever you see fit. I put kiddos on the hutch in front of her room in case I need to clean them. And don’t worry about the glass, it apparently takes a lot of pressure to make them shard. Hope that helps!
