Welcome to Just Answer:
It appears that you have chemical conjunctivitis
due to the contamination. I suggest that you irrigate your eyes with clean tap or distilled water, so you did well. Then continue to use tear drops every 2-4 hours while awake for the first 24 hours, then 4 times daily for about 7 days. In the meantime, use prescription glasses
for a few days if possible, hold off on the any contact. Do not use the contaminated contacts again. If you are able, over the counter Zaditor eye drop 4 times daily will significantly relief the pain and inflammation. If you are not able to get Zaditor, use over the counter Aleve, or Advil (ibuprofen) for pain and inflammation relief. This will resolve. When you return back from the mountain top, I suggest that you follow-up with your eye doctor for closer evaluation.
