I like getting glasses off of Zenni but they never seem to fit quite right, mostly the arms. Would be nice to be able to make adjustments.

Probably ~130C but I would not gamble on this. I have no experience in lenses like this or their specific plastic composition. I just know most are based on polycarbonate, have made my own corrective reading, and my own anaglyph, glasses.
