This product did not work for me but I'm sure it helps other shooters. Just thought I'd give it a try.
I have Decot HY-WID prescription shooting glasses with 3 different colors of lenses. I was able to match each color perfectly. Have only used them once so far, but very satisfied with my purchase.
I have a strong cross dominance and tried the dots for the first time today. The results were amazing. Score greatly improved. I was going to give it a four due to cost but so far the improvement was worth it.
