Why is that?  There's nothing wrong with acrylic -

There could be acrylic in a phone lens, or a photographic lens, or a $10M one of one large optic, or a $50k cinema lens, or any other application - it's not bad.  The f/0.48 lens we have in the lab I work in contains an acrylic element and it is a far more impressive specimen than most any photographic lens.

 

I don't think I've ever had glass eyeglasses.   Some of my plastic lenses have been decent, some have been excellent.  In the end, every photographic image I've created or viewed has had to go through plastic lenses (on my face) at some point.   B) 


But maybe I should change to glass eyeglasses? I really don't know.
