For you Acid, I'd buy Quantum energy eyeglasses. I know you have eye protection measures in place considering you have a lot of screen time (I imagine), but I'd buy you that still.
If I'm to give a random person an abstract gift, it'd be a Stopwatch. Since they'll probably be a stranger, its significance will be a subtle, nonjudgemental, unbiased reminder of when to sprint and when to catch your breath because stranger or not, you matter, and you're seen.
I think I'd give you both Acid ✌️
Yes, you'd think I would have thought about taking care of my eyes at this point. :p
