I never realized until this week that having less than 20/20 vision means that the world looks darker than it is.
I used to have 20/10, eyes that were better than average, and maintained that for years. A couple of years ago my eye doctor recommended "cheaters" for those times when focusing on small print was difficult. For a long time, I rarely wore them at all, reserving them for low-light situations at the end of long days. Tired eyes don't see as well.
One thing I can see is the day coming when I'll break down and get glasses to wear all the time.
