I have buy drops from Hydrasense for dryness of eyes, it took one night and the PATM symptoms has decrease a lot the day after and i work at a grocerystore so I can test it every ******* day. since 2 years my eyes are really sensitive to the sun, and the Patm symptoms decreased when I had a new iphone, so this could be the key maybe BUT I have candida since a very long time and it always feels like it comes from this because of a lot of reasons like allergies coming from nowhere, whatever....I went to the pharmacy buying drops for my eyes because of the cold temperature, I asked the pharmacian for some advices, so if ever someone want to take a try it is HydraSense drops, Advanced for dry eyes, preservative-free, (ingredients of this one are better than others drops)
