Just to add other details I forgot, all about vision issues:
From one month to now, eyes got worse, sometimes when they are extreme dry, I have after-images and light sensibility, also, I see like tiny little grains (some dark, some bright) at my vision, but it comes and goes.
I've made an eye test which shows the back of my eye is ok, waiting for the retina test result.
I use glasses since my teenage, I can see fine with them (although my right eye is a bit blurrier even with glasses, and it´s image is a bit more red than the left one).
