After opening my eyes under water in a public swimming pool my eyes got very red all over. The next day my eyes looked mostly normal again besides my plica semilunaris being enlarged. There is no pain or vision issues. The plica is just bigger than it was before. It's been 6 months since I went swimming and the plica is still enlarged. I'm sure it was the chlorine in the pool. What can I do to get the plica back to its normal size?
