Several years ago while working in Afghanistan on a project building a military camp next to the Pakistani border I damaged my eyes with the moondust (which is like talcum powder and 6" deep where we were working) and the heat and sweat. Ever since then when I get hot and sweaty my eyes get real sore and infected again. Got in hay 2 days ago, mowed and trimmed the yard yesterday and sawed a few small logs in the heat today. Now after the hay dust and pollen, grass and sawdust it is like looking through a fog. I'll try some ointment and drops and hopefully they will be better in the morning after a good nights rest.
