Agree completely, In 2014 I was being prescribed stronger and stronger lenses to address an eye issue I was having. Mid treatment I had a 2 week holiday in Florida with no daily computer access for the first time in 10 years (I'm a software developer) after which I got back to find that miraculously my eyesight had returned to its pre glasses state. During the holiday I'd not needed the glasses as I wasn't driving or using a tablet/computer.
