5 plus years of dry eyes cured.
This sub helped me with my research so just sharing what worked for me.
Background - - long low dose accutane in my 20's. Now in 30s. Some people say there is link. So just added for those who have similar history. Always remember having sensitive eyes after that time. Got worse over years. It got bad enough 6months ago I was struggling to keep eyes open at work in aircon. I took more proactive measures.
I had tried lid cleaning. Hot compresses and dry eye drops preservative free no changes.
I went to optometist to get free check. Lifted lids. All bumpy. Possible allergy. I don't have any known allergies but took note. Also the lower lid oil grades were blocked /not excreting well. Water evaporative test showed quick water loss. So it was an oil lipid problem.
I got myself some opti Mel munuka honey drops and gel. Some cod liver oil. Stopped eating dairy. I eat Paleo with rice.
I used the gel morning and night. I used the drops when my eyes felt sore or inflamed at work. This continues daily for 3 months. Then sporadically as eyes were feeling fine. Which is to say I forgot I had sore dry eyes. Lol. Now I only use if I'm tired and eyes need some soothing. That was 2 months ago.
Summary---I feel the opti Mel was the heavy hitter here. It reduced inflammation and gave my eyes a chance to heal and balance. It can be a vicious cycle where eyes are inflamed so can't produce needed oil which the eye needs to reduce inflammation. The omega certainly can't be dismissed. I'm not certain on dietary changes impact but cutting dairy reduced subtle aches on body which could have been a sign of inflammation.
Hope this may help someone. It sucks feeling like you have sand in your eyes all the time. Good luck.
Edit. I just wanted to add, as I forgot to mention, that the glands got so bad that I was on occasion getting what looked like a sty. And if I pressed down on the lower lid, there would excrete a sort of yellow waxy substance. So just to show you the extent of how bad my glands were
