Definitely not as bad as the author, but slowly losing quality of vision is a nightmare for me. I'm very sensitive to any kind of changes and ~4 years ago my eyesight began to rapidly decline. It's still in very low numbers, but it already affected the comfort of how I live. Without glasses everything is blurry and gives me nausea, with glasses I can see, but it's not the same as having perfect vision. Myopia + Presbyopia, 30yo. It's been ~8 months since last prescription and I already need it updated. Every morning putting on glasses make my eyes hurt for first half hour or so, getting used to "focusing distance" readjustment still. Some days eyes simply feel tired and refuse to focus, yet after doing all the tests, nothing extraordinary was found about my eye issues...
Sigh.
