It's a bit darker than the Ruby Clear I believe, but not by much, and is still amazing for enhancing contrast in low light. I wish I could remember the VLT percentage for the Ruby Clear, but I'm guessing it's got to be pretty close to the original Pink Iridium, which was 57%. Maybe a hair over 60%
Here's a picture I took a while back comparing the original Pink Iridium (left) to the new VR50 Pink Iridium (right). This is about the darkest they will be from the outside
