So last time i was stressed at work and my right eye went blind for a minute and then occurred again when i was working and stressing?

Concerning symptom: Although this can be a bi-product of anxiety, your firm description of "right eye" association is concerning for a vascular phenomenon, which can be an early sign of impending stroke. Let your primary physician know about this so that an age-appropriate screen can be initiated. Hate to be an alarmist, but you want to make sure. Best wishes!

This may be migrain: This may be migraine but since we do not have your age but this can be very serious. I would suggest your physician have you see an ophthalmologist and also a Neurologist to accurately diagnose this.

If it truly: Went blind, as in black like a curtain came down over your eye, that's incredibly concerning. Please consider being checked out ASAP.
