I got a pair of $10 crossfire safety shades I can wear them out side all day fishing then go in and wear them while I grind metal and use them as a little help from flash burn when other people around me are welding. I wear them for everything including driving and if they get scratched or break or fall in the water they were only ten dollars I just get another pair. I don't get why you would pay $300 when you can pay $10.
