You've left the geanie so much room for interpretation, for example:

• Take 30 seconds to do the task of giving all blind people eyesight.
• You didn't say when these 30 seconds happen. Could be all at once now, but could also be everyone at their last 30 seconds to live.
• "Eyesight" could mean that there are eyes sighting the blind one. So there's just someone around that looks at the blind person.
• You didn't say that the people have to be alive. So now, they become zombies for 30 seconds. This means somewhere where there's a living human next to a dead blind human, the living one gets bitten, and the zombie disease can spread.

What are the three wishes that would cause untold amounts of mental damage to marginalised people without death or permanent changes to their daily life?

This is to make sure they are not overwhelmed an hour later when the next wish restores their sight permanently.

Nah gotta make it 30 minutes. That's the true evil.

Jokes on you, I give all blind people 30 seconds of sight once in their life at the single most useful moment. Blind people worldwide regain their sight just in time to avoid accidents, to see their loved ones right before they die, or to save their children from danger.

OP: I knew what I was wishing for...

Bastard.

"Granted."

All blind people get eyesight for 30 seconds at different times while they're asleep

Devil: I must say I am a big fan

This is actually very clever. If they lose their sight again after 30 seconds then that is on the Genie's head. You didn't say for "only" 30 seconds.

Bro really got the whole squad laughing with that one:

😐😐😐😐

Why did I think this site was gonna be better than reddit? Yikes.
