Use the search feature and read about the rocky recovery from ptygerium surgery.
Since the cornea is operated on and cut and scraped and the cornea is the most import focus part of the eye blurred vision is very often a part of recovery, if you wear glasses it usually changes your glasses prescription

I've also had surgery on a pterigium. Since then my sight in that eye is very blurred, although it was near perfect before. it's been 2 weeks now without any improvement on the blurriness.
What could the reason be?
If your problem is comming from blurred vision then yes it can be normal. If it is not then no it is not.
Cover your operated eye and just use the other one for a minute. If that makes you feel better and the operated eye is blurry then the surgery is likely the cause.
If not then see your GP for a general physical.
