Side note: This is more or less a simplified version / original intent of a Magic item in a game I'm playing in. Though as of now in that game it works through activation (i think, and its probably an action like Detect Magic) but as it is a prototype on each activation the user needs to roll a d10(?) to see what happens out of the following things (can't remember the exact odds for each, also probably forgotten a couple effects)

• Nothing happens
• Activates as expected
• The aura emitted from magical sources is blindingly bright
• The glasses help you see Magical things by making anything that's not magical invisible to you
