I've never experienced that, but I have had a number of issues with my vision over the years. My eyesight is off the chart bad, so I've been schooled by my docs to treat any sudden changes in my vision as an emergency. I'm almost always seen that same day. That may sound alarmist given that your vision has apparently returned to normal, but if it were me, I'm not sure I would wait a week to be seen.

When you say you're seeing your doctor next week, do you mean your GP or your eye doctor?

Good luck. Let us know what they tell you. I hope your stress doesn't last much longer.
