Dear all, I suffered 3 years from dry eyes and I've tried everything: doctors, fish oil, flaxseed oil. The fish oil and flaxseed oil reduced the dry eyes, but I had to take 4 capsulas daily. I also suffered from puffy eyes with dark circles and somewhere else on this site I found that dark circles could be caused by eating bread (wheat, gluten). It was advised to stop eating wheat. I stopped eating bread and within 1 week my puffy eyes were gone, but also my dry, gritty eyes!
Now, when I exceptionally eat a bread roll, immediately my eyes start to itch and get red, so it is very clear for me that it is caused by eating wheat, because of the gluten. Many people have a gluten intolerance which they don't know.
If you've tried everything, try to stop eating wheat.
