I suffered with blepharitis and dry eye for quite a long time. The optician gave me eye wipes; the doctor gave me drops for blepharitis and more drops for dry eye. Nothing worked at all.
After some research, I discovered that blepharitis can cause dry eye, or in other words, the two were related so I didn't need anything specific for dry eye - I needed to clear the blepharitis. I also discovered that if my fringe is long enough to touch my eye or eye lashes, it makes matters worse so I cut my fringe so it's clear of my eyes all the time now, which definitely helps.
I finally found a product which worked for me and I haven't had blepharitis for months now and that product is Noveha eyelid and last cleanser containing Hypochlorous Acid which I apply with clean cotton wool. The small bottle I bought to try worked, so I bought a larger bottle and haven't looked back. I no longer have Blepharitis or dry eye. The two disappeared together so it worked for me; hopefully it may work for you.
