Thanks for your reply Mr Brown. I'll never give up plus lenses. I believed that since I spend about 180 minutes per week of eye exercises during the strong PVS schedule, maybe I could get some good results per month (the previous month was a good one).
Maybe by doing these eye exercises I will be able to wear strong plus lenses (+1,5D) at home and not just +1D which I use when seeing the screen of my computer at ~60cm.
