I got LASIK about 10 years ago. Can confirm both the visual experience of watching them laser/scalpel my lens off, as well as the highly unique smell of buring eye. Along with the painful light sensitivity that persisted for like a year. Hell I got a USB at the end with a video of the procedure to relive.
Totally worth it though
I have seen some cars flash their brake lights when ABS is activated, but this would be better
