I'm an Optician. I fabricate, fix, repair, and adjust eyeglasses. I fill prescriptions(like the ones jota writes), and help people see. The root of my experience in this line of work is fabrication. I start with a hockey puck sized hunk of plastic, and turn it in to something that allows you to perceive the world in an acceptable way. As a lot of you are learning, I'm the a$$hat that expects to be paid for helping you NOT squash anyone when you're behind the wheel...so you may continue to function behind the wheel...or in front of the computer screen...or whatever you can't see these days.... Except the future.... I can't help you see the future...for that, you're on your own.
