Best way to fix these cracked glasses needed

My two year old stepped on my glasses while at a picnic. I wear these daily and it's hard to find a suitable replacement.

Frames are plastic . Lenses are plastic and not prescribed. These were about $20 (us) and the brand is from a fishing line of equipment called Ugly Stick.

I have tried to find this exact kind again online and have not been able to find them. I have another pair that is adjacent to these but they look differently because of the colors and the lenses are a different tint.

I would love some advice on how to fix the plastic frame so that it will be sturdy again.

I'm not sure what other information I can provide about the glasses or what questions I am failing to head off, so please ask away.

Thanks in advance.
