I'm pretty near-sighted, I have to wear contacts everyday just to see!
Me too! It is also known as myopia or short-sightedness. 
I always get them confused, myopia means you can see things up close and far away things are blurry, right?
Yes that is correct. Distant objects would appear blurry and objects close up appear normal.
Ah, yes, I wasn't sure. I've always had myopia, it's awful.
Me too and is has caused me many headaches due to eye strain.
So, there's short-sightedness and far sightedness, but are there any other vision defects I should know about?
Astigmatism and presbyopia are also types of refractive error.
