While I was at work, it was very hot there not sure if that helps. I had a sudden onslaught of floaters in my vision and they were like ‘cobwebs’ if I remember correctly. This hasnt happened before and I had to go outside where they disappeared. It was only temporary and I only seem to experience this when I am in that workplace. I felt like fainting and also gagged with no reason whatsoever. I felt sick but after going outside I was fine and when I went home it was fine too.
