Blurred vision??????

I really need info on an eye issue I had today that I have never in my life had nor does anyone in my family have.Today I was reading nutrition info on the back of a nut mix label when I went to read it it was small so I had to hold it closer to my face I held it about a half to a foot from my face and I couldnt read it Ok I thought maybe I had something in my eyes so I rubbed them then proceeded to try and read it again and I could not it was completely blurred out like I was going cross eyed and my eyes hurt.I have never had an issue with my eyes never,no one in my family wears glasses just the other day I was reading small letters up close it's like this just happened over night what could be causing this? I am 32 isn't that too young to start having bad eyes? What could be causing this?any info would be much appreciated Thank you.
