Anybody ever get this after working under HID's or LED's?.. It's an event that starts off randomly after exposure to bright lights. It starts as a blind spot in your point of focus. You can't see what you're looking at. Then this C shape starts to develop with flashing diamond/multi-colored lights that gradually over about a 30 min period moves to the left and the C gets bigger as it moves left to your peripheral vision. I first got one in the 2000's when I started an indoor closet grow with an HID. I haven't been wearing my MethodSeven glasses in the grow lately because I've been wearing a bucket hat, but i do occasionally catch a glimpse of an LED panel. I've had 3 events this week... just got through one. It's usually followed by a crushing headache. As soon as I see the blind spot, I take a couple of Advil. First time I ever got it, It freaked me out. I thought I was having a stroke or something. As I learned more about it, I saw drawings on the Internet of what I saw, and found it was quite common. I was just wondering if you guys ever get this?.. or maybe it's just more common for certain people?. Anyways, now I just sit back for 30 min and enjoy the light show until it passes.... Prob need to wear my M7's more.
