Is there any way to buy eyeglasses without seeing an optometrist?

I know what my prescription is – it hasn’t changed in a couple of years, and I’m fine with what I have.

My frames are on their last leg – my son has nearly snapped them in half. I don’t want to go to my normal eye doctor, because he charges an arm and a leg for glasses, and I don’t have insurance.

Is there any way I can just buy the glasses I need from somewhere? Perhaps online, with a steep discount? ^_^
