Yes, Rob, I can attest to the efficacy of the baking-soda-in-water eye wash. It helps for itchy eyes, red eyes and probably for some other eye woes.
I have redness in the corner of my left eye. I have had it over a year. My eye also produces and lot of sand and grit. My left eye always feels tired even after just waking up I read about adding 1/8 teaspoon of baking soda to an 4 ounce glass of water and splashing it in my eye and drinking it. After doing this, almost immediately, my eye felt better! Can't recommend it enough:)
I've found that my burning eyes could be helped by applying a solution of Baking Soda in water to eyelids and get instant relief. And a while back my sister reminded me that my grandmother (who lived to 103) would start her day off with Baking soda in water and wash her eyes out with the solution...not just applying to eyelids. I've been doing that for a few weeks now and find my eyes don't burn nearly as much, even when I've had too much acid foods during the day (coffee, Tex-mex).
Baking soda works much better than prescription eye drops for me. It lasts longer so you don't have to apply as frequently as drops and it is more effective as well. Stops tearing and more soothing. One eye seems to be cured while the other still gets watery. When that happens, I apply remedy to lid as someone on EC recommended. Then when it returns, I do it again. Much happier that I found this remedy.
Had dry eyes for years and in my case found it was acid related. Tried lots of remedies but the best is to dissolve a third teaspoon baking soda into a half cup of purified water. For safety sake, boil the water and let cool. Dab with clean cloth onto eyelids; repeat a minute later. I repeat: Apply to eye LIDS. Keep eyes closed until dry. The alkaline water will counter the acidic condition on eye surface.
I drink then the remainder of the baking soda water to offset my acidic system.
If I drink coffee, the dry eye problem is worse. Eating acidic foods also worsens the dry eye.
The point is: my dry eye condition was being caused by an acidic system. I had been diagnosed by an opthomologist with "dry eye" and the solution was to counter the acid in the body which I suppose had caused the dryness.
