What i need to do

[san_sight]

I am 28yr Old male have glasses for astigmatism .I remove my glasses only when i go to bed righteye -8.50 left eye -9.50 (they make me feel like I have tunnel vision).  My question is why my vision becomes very blurry when my eyes are fatigued??  My eyes also do this shutter back and forth thing when I try to look at things up close.  Its like my eyes involuntarily twitch from side to side when I try to focus on something small.  Is it just muscle strainStrains ?  The shuttering or twitching is kind of scary.  The blurriness causes a problem when i'm driving.  Thanks in advance san

Your prescription may be too strong.  See an ophthalmologist.
