Why am I suddenly more intolerant of the blurriness that I get when I take off my gles?

I've been mildly nearsighted all my adult life but my prescription has never gone beyond -2. I've never worn them full time but am finding that life in soft focus is becoming annoying so am wondering whether I should just keep them on. I generally wear my gles indoors as I can see better with them on but other than that I put them on and off most of the time. My prescription is relatively up to date so why would it be that I am suddenly more intolerant to blurriness without my gles? after putting up with it for so long I'm struggling to understand why it has become so annoying.
