For an OTC dry eye drop product, my optician recommended Refresh Optive Mega-3 lubricant eye drops enhanced with flaxseed oil. I don't know how special they are, depends on how bad your condition is. The 3 active ingredients listed on the box are carboxymethylcellulose sodium 0.5%, glycerin 1%, and polysorbate 80 0.5%. No warnings listed as to overuse.
It would be nice to see if a medication review has been done comparing the different products. Like under Drug.com or similar website.
Systane is a well known brand....https://www.amazon.com/dp/B0BRNTR8Q8 At Amazon - $22 for 2 bottles, 10 ml per bottle.
