Digital agency Zone will create all editorial content for the site, which is set to launch at the end of this week.
The Ray-Ban Rooms site backs the brand's summer music and festival activity at events such as Glastonbury and T in the Park, as well as its venue at the Isle of Wight Festival, which takes place over the weekend of 12 June.
Site content will include live Twitter updates from festivals and exclusive video streaming of performances by artists including The Charlatans, The View and Josh Weller.
This is the second year that Ray-Ban has developed a dedicated site to support its festival presence.
