This seems like an Appearance issue, so I'll post here: I have mild myopia(2.5 in each eye) and astigmatism(1.5). When jackin off wearing my glasses(not sure when using contacts) I notice that my dick seems a bit smaller than when without them. When I do it with no glasses I'm always taken aback due to the apparently new massive size. I remember some information about divergent lenses that I've learned when I was in high school: they do really "shrink" the image. It's not a life changing topic but I was wondering if someone else also noticed this phenomena. I also would like some clarification if possible: Due to the myopia do I see things bigger? Or the glasses make it look smaller? Or I'm completely wrong and this size difference is only a trick my mind plays on me?
