I am very allergic to the preservatives in many eye drops.
Through trial and error and with the help of my ophthalmologist, I now use Systane Ultra - individual doses of drops in small sealed, sterile tubes.
The individual ones are preservative free. (other brands are too, when packaged this way)
I keep mine in the fridge- they are extra soothing when cool. My doc said they can be used every 5 minutes you like…. very safe.
They are also good for flushing/rinsing if you get a speck of something caught in your eye.
I buy them at Walmart- lots of stores have them. Costs about $10 a box, but well worth it.
Good to use before sleep, too.
