I was about 27 years old, it was a combination of very bright LED signs on the freeway being unreadable, and not being able to read the aisle signs at Bunnings (a home improvement store, like Lowes). I definitely had perfect vision somewhere earlier in my 20s, so it seemingly deteriorated rapidly relatively to my -1 on both eyes that I am now.. but slow enough that I didn't notice for quite a while. I had basically decided things just get blurry further away and not really noticed. Probably does not help that I am in front of a screen 12 hours a day like most :)
