Ask HN: Nearsighted from Computer Work. Others?

I have approximately 10 hours of screen time per day. Typically, experts recommend following the 20/20/20 rule (try to look at something about 20 feet or approximately 6 meters away for 20 seconds every 20 minutes), but I never adhered to it. As a programmer, I suppose I’ll always have high screen time. I’m planning to have LASIK surgery in a few months. Has anyone else experienced this? Did you become nearsighted or manage to overcome it?
