We spotted Robert Downey Jnr on the red carpet at the LA premier of his new road trip based movie Due Date in a pair of funky lilac tinted glasses and thought "ooh they look cool!"

We asked Eavan Kennedy at EK Eyewear and not only did she know they were Oliver Peoples but Eavan is ahead of the game as usual and will have them in store soon.

"This frame is the latest in the ever-evolving frame collection from Oliver peoples. Robert Downey Jr. wore the Jack One frames with custom lenses at the LA premiere of his new movie, Due Date and he wears the Benedict Gold-Chrome Amber throughout the film - also by Oliver Peoples. "

"The Jack One is a very different shape and not for everyone!" noted Eavan, "They are incredibly cool - so one for the really brand aware guy that wants to hit a trend before everyone else."

The Jack One frames come with the options of two photo chromic lenses, which change in the light conditions (bluey-grey and warm golden pink ) and two with polarised lens options (grey and brown).

"The Jack One frames retail around the £230 depending on options and yes - we will have them at EK Eyewear."
