Can the temple be shortened?

I saw someone say that opticians can cut the temple length to make your glasses fit better? My old glasses fit perfectly at 130 mm temple size. My new glasses are 145 mm and won't stay on my nose. I brought a previous pair to LensCrafters to bend the arms to fit my ear better, but I can't say it helped very much. I don't know that just bending the legs will help these stay on any better. What can be done?
