Collection sun damage paranoia.

I collect video games, and I'm obsessed with not damaging my games. Sometimes it's even hard for me to play them, because I fear causing some sort of damage.

These past few weeks I've kept my games in cardboard boxes, because I'm moving soon. The boxes lie close to a window. and I just realized, that there are tiny holes in the corners in the top of the boxes, where tiny rays of sunlight might have entered and caused some damage, and I feel really really bad about this.

Do you guys know a way to calm oneself in a situation like this?
