I developed dry eyes this year. Went into Optometrist for a painful eye, thinking something was in it but made the whole eye socket hurt, headache. Turned out it was Shingles in my Retina and Dry Eye. Turns out having Parkinson’s I blink less often so I don’t create enough fluid in my eyes. I have to purposely blink more often but also use drops. Air blowing in my eyes is almost torture. I thought back for the last six months, I kept thinking my allergy meds were causing it or mascara dropping in. Sometimes it really good to get an answer to something really irritating 😂
