The brand is Sleepfun. I got a 2 pack for around $10. I use it to escape light when nothing else works. I had to give up night driving a couple years ago due to photophobia but, even as a passenger at night, I struggle with the lights and contrast of the darkness. The blackout mask was the only way I could ride at night. Also, the dentist lights hurt terribly so the mask has been a huge relief for cleanings and fillings. Sunglasses dont cut it for me in these circumstances.
