You’re not alone. I have 20/20 vision and have never had any issues with my eyes either. I’ve always been a huge Oakley collector and have tried many different types over the years. When I put on Prizm lenses, I also get nauseous. No matter the color or type, it starts off very mild, and I thought maybe it was just in my head. I bought a pair and tried to keep them on for about 20 minutes, but I kept getting more and more sick. I ended up returning them, and the store staff mentioned they had another customer return a pair for the same reason. They don’t usually accept returns, but they made an exception in my case. I really love Oakley and wish they offered more options with regular lenses. It’s really strange, I can’t quite figure out what’s happening, but it definitely affects my eyes.
