Yes, I do have the arms length, but not the 22 inch size. I also know that having my elbows on the table, not hanging off the table from using the keyboard helps! I know posture is a problem, but I try. I think looking away ever so often helps to keep the eyes blinking and not drying out. But, as for the blurry vision, I think there is a market for whoever makes one to deal with this.
