You might ask your doctor or ophthamalogist about using eyedrops. As
a GD survivor I have been using eyedrops for years, as often as once
a day or several days a week. It’s another fact of life with GD. There is
a heavy duty eye drop that can be put in just before going to bed (it’s best
to do it then because your vision will be blurred for little while after applying
it) that is really good for gritty eyes. It’s called Refresh PM. All these
are over-the-counter, but you might want to ask a pharmacist which are
best for long-term use. For instance, you don’t want to use Visine (spell?)
or some of the drops that are just for short-term use. Good luck, and
hope your eyes feel better soon.
