I had a laser procedure on my eyebrows and even with goggles, my vision was permanently damaged from the zaps. I could see the red flashes of light during the procedure which refracted my eyes. I have horrible night vision now with the starburst effect and glare. Lasik helped somewhat, though. Good luck!

i think it is just normal..because i experience the same thing also, after my own session of laser hair removal..but it was gone after a good night's sleep..

seeing flashes of light even when eyes closed is pretty much normal.
many clinics used those kind of googles, you could have also used gauze.
