Jim, my vision is crap unless I use my eye drops. Dry eyes are more than irritated, it does influence your ability to focus well. Over the counter moisturizing drops (NOT vasoconstrictors like Visine) are something that should help you out, especially when you first wake up in the AM, and sporadically during the day. I use an Equate (WalMart brand) copy of Refresh Plus - singe application vials that you can just keep a few of in your pocket.
