Sunlightwhen target shooting what makes the reticle fade from sharp black to kind of gray ?
I had the same problem with a similar reticle, especially when in bright light conditions when the pupil contracts. Just so happened I had an eye exam coming up. When I mentioned it to the doctor, she looked closer than just the normal exam and found I had a cataract forming. Too small for a surgeon to bother to deal with at the time. I'm still waiting for it to grow enough for surgery (5 years now!), but I did change to a slightly thicker reticle. Worth a thought.This happens to me with a fine cross hair with target dot. When I first look the cross hair is fine but fades after looking too long. It doesn't happen with thicker cross hairs.
