A laser that can kill a fly in the fraction of a second has to deliver enough energy to fry your retina even though a dozen sunglasses. Also consider that the laser is focused down by the lens in your eye which greatly amplifies its power.

That's not how specific wavelength safety goggles work. You can get both near UV blue light 440nm 5 watt goggles, and infrared depending on the laser.

Problem is they tend to shift the color of light for everything so much that they aren't pleasant to wear for a long time.

My worry would be getting hit on the skin, a 5 watt 440nm laser hurts, and it's a deep burning pain that doesn't go away.

Why even pretend my reply was about safety goggles? Obviously a huge difference vs regular sunglasses.

I thought it was obvious I meant laser safety glasses.

With the line about looking cool wearing them indoors??

stupidly stylish safety glasses

A angle laser is nowhere near as fun as an array of lasers anyway
