If you have autoimmune, you can have more than just aging eyes! I've also had cataract surgery. I have discovered that my eyes get blurry about as often as they feel dry. I use drops frequently throughout the day. An allergy pill and washing your face periodically can help during allergy season. I gently scrub my eyelids in the shower to activate tear ducts. Besides Systane, which I like most, I use PM Ointment at night for the days when drops are not enough. I have a prescription for Pataday which I use daily when it feels chronically gritty. The Pataday (prescription) is spendy, but makes a difference. A loose eyemask at night (no pressure on eyes) is very helpful, particularly if you have a fan running or vent aimed at the bed. I wear sunglasses outside if there is air movement and if I am on the computer for many hours. Hope this helps. (I have symptoms of Sjogrens, which is the root of my issue)
