Why does my vision become foggy when i wear contacts and i need to blink a couple times to make it clear?

I just got Focus Dailies and I have this problem sometimes.Why does my vision become foggy when i wear contacts and i need to blink a couple times to make it clear?
This is normal for the toric lenses. They rotate to correct astigmatism and I usually have to blink a few times until they rotate into place.Why does my vision become foggy when i wear contacts and i need to blink a couple times to make it clear?
that happends to me sometimes to.


but im not sure what it is, sometimes i think its because i didnt clean them well or its time to switch to new ones


or my eyes are just really tired
that happens to me all the time because i don't clean them as much as i should.


all i can suggest is to NEVER sleep in them (i made that mistake) and clean them daily =)
