Lee B wrote a review of Julbo Explorer Sunglasses - Alti Spectron 4 Lens on December 14, 2011
I have had a pair of these glasses for several years. My eyes are very sensitive to light. I use these on the water, in the mountains, on bike (motorized and pedal) and anytime I am outside. They are amazing. Easily the best glasses I have ever owned. They are equal to the two pairs of Julbo micropores (glass lenses) I also own. I was worried about the lens durability of the spectrons but they have been great. They are much lighter than the micropores. I find myself wearing these more than the micropores. I will definitely buy another pair when these are done.
