My ophthalmologist told me after my last visit to use plain eye drops to add moisture for my "aging eyes" when they feel scratchy, a bit dry, etc. I asked him which type or brand, but he said any eye drop without extra additives was fine. I've been using original Systane without preservatives and haven't tried any other brands. I read what some of you are using and was just wondering if there is something that would be better that you would recommend and I could try next time I buy eye drops. I haven't had any issues with Systane and it does the job O.K, but doesn't leave my eyes feeling anything exceptionally soothed after using. I have had cataract surgery on both eyes in the past and my vision is generally good.
