if you have astigmatism thats how dotsights appear, its normal.
you can tell if its the dot or your eyes by taking a picture through your dot sight. if the pic looks normal like a round dot and the sight while looking through it appears fuzzy or star pattern its your eyes. if both are the same its a malfunctioning sight.
