Eyesight problems with anxiety?

Sometimes when I am anxious my vision becomes obscured. Like I am looking through water in the lower half of my eyes. This has lasted up to 15 minutes at a time and is very scary as I can not see to read through the lower part of my eye.

Also, sometimes I have a tear that appears in my eye and stays with me for hours during my incessant anxiety.

Does anyone else have these problems?

Yes, I've had vision problems with anxiety. This is a fairly common problem, but I agree that you should have and eye exam if you haven't had one recently. If nothing else, it will put your mind at ease.
The reason that we experience visual disturbances is biological. The fight or flight response during A/P causes changes in the eyes (and vascular system around them) supposedly to help us to focus in a sharper way, allowing us to escape harm. I don't know how one can escape harm, stumbling around with blurred vision but that's the explanation from the experts;)
Try to get an appointment with an opthamologist (optometrists are not medical doctors) and let us know how it turns out.
Take care,

I think I may experience something similar, but I've had it for many years. Long before anxiety was ever an issue for me I went to the doctor and got all kinds of tests for it. They never figured out what it was for sure, but settled on "ocular migraines". In the future they said I'll likely experience painful migraine headaches, and they were right about that.

My vision oddities will appear at random times, but anxiety absolutely makes them worse. It's usually in my left eye, and at its worse can render me almost totally blind in the affected eye. It's sometimes accompanied with dizziness, and rarely that dizziness could probably be characterized as "severe". Also, now and then it will feel like my eyes are crossed, but I will ask people if they are and they say they are not. These days, about a quarter of the time I experience these vision problems, a crippling migraine will occur shortly thereafter. Most of the time they just go away without consequence, and the problems never last long.

Like I said, it's mostly in my left eye, but it will happen in the right eye now and then. Only once that I can think of has it occurred in both at the same time, and that was really scary.
