since starting copaxone I have SEVERE dry eyes! I even had punctal plugs put in the lower lids to keep what moisture I do have IN there. There are several nice over the counter drops that can help. Make sure you get preservative free ones. The single size ones are great. Systane, and gentear is pretty good. Its awful when you wake up in the middle of the night and feel like your eye lid is glued to your eyeball, and you cant move your eyeball. A good check up by your opto is a good idea. make sure you dont have any infection going on. I use a Venta room humidifier, and keep myself well hydrated. Drink drink drink.
