If the dot/reticle appears blurred or frayed, there are several reasons for this. The most common
mistake is to focus on the reticle (dot/circle dot) when looking through the sight. You can check the
correct display of the (weg lassen red/green) reticle by looking into the distance while looking
through the sight. Then the reticle and the visual image, both, become clear.
The brightness setting of the reticle also influences the display. (weg lassen of the red/green point).
The sight is often set too bright for the ambient light conditions. You can see this, for example, by
the halo effect in the inner tube. Please try reducing the brightness by a few steps and look into the
distance again. Your reticle should now appear sharp.
Another option for checking the reticle is the eye relief to the sight: Take a photo of the reticle by
focusing from about 30 centimeters. The reticle image should then be clear.
Sometimes the blurred perception is due to your eyes themselves. You can check this by focusing on
the blurred part and then turning the optics clockwise or counterclockwise a few times. If the
blurred part rotates, then there is a defect in the sight. If the blurred area does not turn, this could be an indication of astigmatism or other impairments of perception.
Due to the coatings on the lens of the optical sight, a certain glare will occur in reflex/reflective optics. Glare is more noticeable in low light, indoors with ceiling or background lighting. Glare is exaggerated when the optic is held in the hand instead of being mounted on a firearm.
