Went skiing today with flat light conditions and got super dizzy. Is there something wrong with me or does this happen to other people?

Disclaimer: this is my first season skiing.

I have experienced flat light before on certain runs but today the whole mountain was like this, ESPECIALLY my favorite green runs. At a certain point while skiing, I couldn’t see any sort of features in the snow so I was kind of skiing by faith but what started happening was I had these…blotches in my vision. I don’t know how to describe it other than that. Just a lot of gray spots that got progressively stronger until I had to take a break because it truly felt like the tunnel vision you get before fainting.

Having searched this subreddit for that, I figure I must go get myself some good goggles for these conditions but uh..is that normal? I couldn’t believe how disorienting and dizzying it was. I hope goggles fix it but just wondering if anyone else goes through this and if this has a name? Or if this is a medical thing I should be concerned about lol?
