RUBY lens.
I was lucky and ended up getting a RUBY lens that is similar to earlier batches. They have lots of dark red and very, very little orange and no yellow. When looking through the lenses they are a blueish hue. They are gorgeous. Easy to swap out the lenses and change the look of you DOGS.

Now with Ice, Fire and Ti Clear options - makes MD replacement lenses a great alternative to creating your own customs. Best of all, the MD is one of the easier styles to swap lenses in and out.

There are a very large variety of color options of lenses for the Monster Dog available now. It is a very nice way to mix and match for unique styles. I was very happy that Oakley made Ti Clears for the MD's. It is also fairly easy to change out the lenses as well.
