I am a newbie here but have had same issue. I rinse eyes every morning and night with Collyrium eye wash to get rid of any foreign objects. I also rinse eyes, nose, ears every morning and night while in bath which is diluted with Epsom Salt and tea tree oil. This helps manage the situation for more comfort.
I've also found that eating tons of garlic (yes - at every meal, several cut up cloves), pumpkin seeds (mucho) and tons of water with lemon really helps flush things out.
