I can't see anything.

Exploration Stage: Secret Room
From: Isabelle
Description: While you are scouring the tombs, I have prepared for you a pair of sunglasses specially made for you. You must never look at anything on your way to Kalon. Didn't I tell you that? Sorry. Let's practice a little, close your eyes and look for the sunglasses in my study.
Completed: How did you manage to find it blindfolded? I didn't even have to teach you how to do it.
