My ophthalmologist here in Louisiana recommended the same thing, except he added washing the lids with johnson & johnson's baby shampoo. 70 years old and I couldn't have renewed my driver's license eye exam because of blurry vision. He said it was dry eyes (with uveitis) and suspected Sjogren's so he requested blood work which returned all normal values. So I guess I am in that 20%! He is pretty much convinced it is SS. By the way, after using eye drops for 3-4 weeks, passed my vision test with flying colors. Am driving as I always have. Then came Hurricane Ida on 08/29. Still trying to recover . . .
