Because of my Allergic Contact Dermatitis, ACD, a form of eczema I must avoid ingredients I'm allergic to. For dry eyes I've tried all brands like Restasis, every over the counter and prescription product which should have been allergy free for me burned my eyes.
I make my own eye drops which I put in all the eye drop bottles I bought which burn my eyes. I only get a brief sting if the eye is very dry, it goes away immediately with no negative side effects.

Eye Drops-
1 cup boiled water
1 teaspoon salt
3-5 drops of glycerin
A cleaned and sterilized small funnel which can be inserted into the bottle opening. I have small sizes on Amazon.

Sterilize glass mason jar and lid to store extra product in the refrigerator
Rinse to clean empty eye drop containers
Boil water in glass measuring cup in the microwave and add salt, stir with clean utensil
Cool
Add 3-5 drops of glycerin adjusted to how moisturizing you want it to be, stir
Fill empty eyedrop containers funnel, no need to refrigerate
Keep multiple bottles handy around your home
