How does one count the glasses coefficient?
Just guessing, but it might be related to the "olev" coefficient. The more olev she is, the higher her glasses power level.
Saori from GuP and Tamako.
We know that because they switch to glorious glasses at home.
Characters that switch between glasses and contacts in different situations are fine by me.
Characters that permanently abandon their glasses for contacts like that one Love Live slut are literal human garbage.
