I've had eye pain and eye strain for two years. For the stinging, I use Systane Ultra eye drops several times a day. The thing that has helped the most with the eye strain is Flexeril (a muscle relaxer). I've also gotten mild relief from massage and from applying heat to my eyes and neck. I keep a sock filled with rice that I microwave for a couple of minutes. It stays warm much longer than a hot washcloth.
