I have a slight astigmatism and LED red dots always look smeared to me. I’ve found green helps and did on another purchase Holosun 510 green dot from extreme tactical. But I heard HWS may be better. This is a great sight and I have no smearing on the 1 MOA centre dot or 68MOA ring. The ring as with any other HWS looks ‘patchy’ when looked at directly, but clears up to a solid ring when concentrating on the target. Would recommend the sight and seller to anyone. Delivery was quick at approx a week.
