Aeronautical engineer? Explains the big fuss over eye protection. Pilots bring the aircraft to a low altitude and slowly depressurise the cabin to allow the doors to open in an emergency. Which is what they do over the sea and is why people are given life jackets. They would give parachutes, but it's not cost efficient. You're engaging in an arrogant stick up your arse mentality. And fucking hell, now you're glasses came from super ballistic glasses to needing another pair of safety glasses to be worn over them. The points I raised you refused to address because you have magical glasses and don't need safety glasses, oh wait.. they don't work. And not wearing what many people don't wear when shooting is now me gambling with my life? I just gave you several examples that you didn't even address. How many accidents can you list of the slide retracting off the frame and into the face? The only thing it will protect from is debris and ricochets. Which is more common than a freak malfunction. Most malfunctions are to do with the ammunition, which I would of agreed with you. But you resorted to petty insults and acted like a child so I thought I'd entertain this by making my hypothetical points and arguments of personal safety. They aren't needed. Are they safer? Yes. But they are not required and will likely not save your life unless you're being irresponsible to begin with
