Not quite sure if they still make the Dante with the 555nm. There are some on ebay at the moment, that's where I got mine. I was so impressed I bought a second pair for spare as they were less than half RRP. The frames look delicate but but are strong as and just seem to retain the original shape. I had the drivers gradient lense (brown) in my previous serri's, they are good but the 555nm is something else, you just seem to always want to wear them. They block the same amount of light as the drivers but somehow brighten everything up.
