Julbo Venturi Photochromic Sunglasses

Interesting. I didn't notice how old your post was. Good to know they were so helpful.

They were dud lenses. I had them replaced by the good people at julbo.

Also, were you in the car when you tested them? Most photochromatic lenses won't work when inside a vehicle because they react to UV rays which are blocked my the factory film installed on vehicle glass. Also means that they don't make for good driving glasses. I confirmed this with a Julbo rep a year or so ago.
