Cloudy Glasses are one of the armor items sold by Gerson in Waterfall. Their offensive counterpart is the Torn Notebook. They have a low amount of defense, but they increase the number of invulnerability frames the protagonist has. When paired with the Torn Notebook, they almost guarantee the protagonist only 1–2 hits from an enemy attack.
- The item check for both the Cloudy Glasses and the Torn Notebook explains what INV means in parentheses after the initial statistic check to help players understand its use (since INV could be misinterpreted as "inventory," for added inventory space.)
- During the Sans fight, it does not increase invulnerability frames noticeably. However, it does slow KARMA somewhat significantly when it is in lower amounts.
- Since their sell price is higher than their buy price, Cloudy Glasses can be farmed for GOLD. This is more efficient than Dog Residue farming.
