I can still remember the days when I had to carry two pairs of glasses, one on the end of my nose and another in my pocket. What a nightmare that was especially when doing things such as presentations that required me to continually switch between both pairs.
Then I tried varifocals and they were just so uncomfortable that I continued to use my reading glasses for computer work. That was until one day when I forgot to take them into the office and I was left with no choice other than to use the varifocals, and from that day onwards I've never since needed my reading glasses.
If we have no choice in the matter then it's amazing how we can adapt to new experiences. Had I not forgotten my reading glasses that day, it would have taken me much longer to adapt.
