I was sitting in class and I noticed spots in both my eyes like I just looked at a bright light. Now I have a blind spot to my bottom left field of vision and words don't look right I'm freaking out that it could be retinal detachment. Could this be in my head or will it just go away? Is this just anxiety?
If you suffer from anxiety this could definitely be just an optical migraine. They are very common with anxiety sufferers and are harmless, just very annoying.
My friend gets them when she is overly stressed, she said she sees white spots everywhere. My dad also gets them but he referenced more of what you said, he will have like a blurred spot in his vision that doesn’t go away.
If it doesn’t seem to go away maybe take a try to the eye doctor? But it sounds like it could just be an anxiety symptom if you have been overly stressed lately.
i got those when anxious. they go away , then i may get a headache afterwards. all due to stress.
but have an eye exam just to have peace of mind. 
I’d get it checked. It could just be anxiety, but it’s still best to rule out something more serious.
