My boyfriend is blind and we trip regularly. He has some usable sight when he's sober and it's light out but he can't see details at all. When he trips, he has no usable sight and needs help navigating. (He can navigate just fine using his cane in no visibility when not tripping.) Colors get a little more vivid for him. Sometimes the awkwardness that comes from tripping, such as feeling like people are looking at you or thinking "they know" is more intense for him because he can't see if people are looking at him or not. Sounds get more intense. During one trip, we sat in the woods for a long time and I got lost watching the trees do yoga then he spoke up about how incredible the birds were. I hadn't even noticed the singing of the birds. We were both totally absorbed in the beauty our senses were taking in, they were just different from each other.

I haven't gotten there quite yet, but I've taken nitrous before. The floating/flying sensation was pretty epic! I did take it in a safe setting, the dental office. However, I must be sensative to it because I went on a pretty big trip both times. It was much fun!

I'm visually impaired but to the point I can't legally drive or would even dare to try. I tripped a couple times and I just recall seeing the same but everything was much darker and the lights much brighter. One time I saw my hands bleed lol

I've not done any but $1. $1

Basically, nothing terribly interesting happens, IMO. Compared to non-blind anyway.
