Your personal Tumblr library awaits
There are about 2 people I'd let mess with my glasses: My best friend, and my boy toy (who has never actually seen me in my glasses and doesn't know that I've never really seen the details of his face particularly well up close) I'm far sighted and have occasional issues with vertical nystagmus in my right eye due to a traumatic brain injury as a teen so I don't generally wear them since I do alright with compensating unless it's night time or I'm dealing with a migraine. But! They've expensive as hell with fancy prism lenses, like 4 different specific coatings, and they're an older frame style that I just buy new lenses for every few years. The lenses alone cost me almost $500 with my insurance. My best friend has touched my glasses twice during wine and whine nights when I've passed out on the couch, and boyfriend doesn't know they exist, but he's going to figure it out fairly soon because I'm sick of not reading before bed when he comes over.
Read enough stories featuring characters who very notably wear glasses, and you start to notice certain trends in romantic scenes.
