Are you sure you're not using some product that you're allergic to? I only ask cause a couple of months ago i started having the same symptoms with my eyes. It would go away and then come back. Then i finally figured it that i was using a scented(perfumed) hand scrub. Apparently i was allergic to the perfume that was in it.
This is the product i used to help with the eye irritation..it really worked well!!
Opcon-A Eye Allergy Relief 2 x 15ml, .5 fl oz
Hope you find out whats causing it soon! Feel better!
