How do I make a permanent bend to my plastic eyeglass frame? What do I use to soften it up?

Question

What hot solution or substance should the frame be dipped into before being bent into an adjusted shape? If it's not readily available, where do I get it? What's the professional optician's way?

Answer 1

place in hot tap water, for about a minute.
Along the length of the ear frame only
then gently bend, be careful, too much will cause it to break,
Then place in cold running tap water for a minute, to set while holding the shape

But for best results go back to where you got your glasses.

DO NOT use any open flame or direct heat source

Answer 2

Heat it over the electric heater for couple of seconds when it soften give it the desired shape.
