Since I was a child, every summer - especially when exposed to sunlight - my eyes get red, itchy and have other allergy symptoms. I have made several allergy tests on the skin or blood-tests, and none have delivered any results. Literally, the only thing that helps is cortisone, but I know that it's not good for my eyes.
Isn't there some way to finally detect this allergy? My eyes are getting worse and worse each summer, there's now an ugly permanent red spot on my right eye that is small/light brown in the winter, and big/red in the summer.
