Because I see little by little, here in the coffee shop we will gather, to share my experience of yesterday. Yesterday after many hours on the PC I lay down for a couple of hours to rest. When I woke up, I thought my vision was blurry, but I say it must be my imagination. Coffee and I turn on the PC. And yet I saw nothing. All letters joined, blurred. Well I say that's what we missed (I'm not nearsighted either). Anyway, don't talk too much, the ophthalmologist gave me a lubricating eye solution, and he told me because I spend too much time on the computer, I forget to open and close my eyes, they dry out, plus the cigarette smoke, the blurriness comes. After using the solution, I'm ok (at least physically, because my wife has driven me crazy, I told you, you'll go blind, they're doing a good job and they cut the bet, and I feel like sending her a package to her mother...) .So you also shed a tear now and then....
