The superman effect is that ppl do not immediately recognise someone with and without glasses. So, it's natural to be surprised when you see someone without their glasses, because they do in fact look different.
They won't look super ugly to super hot, but it can definitely affect attractiveness to some level.
Some glasses can def make someone look uglier (and vice versa) but there are more factors that make it less attractive (dull lenses, deforming lenses, ...)
When will the glasses made an already gorgeous person unattractive trope gonna die
