These frames official title is the Ray-Ban 'RB6355'. According to Ray-Ban's website they are available in 5 colours, mine are the gunmetal and black, and I'm pretty sure they come in more than one size. I haven't found them available online but I know someone who has the exact same frames but the lenses are smaller in diameter.
The lenses in mine have a fairly noticeable purple reflection. This is only down to me choosing to add an anti-reflective coating to the lenses, which reduces glare when using screens. I don't notice any change in colour when wearing them but it is more noticeable to others in photos and in person.
I had been on the lookout for new frames for about two years before getting these. Not seriously searching just keeping my eyes open for inspiration. I loved my old clubmasters but I'd had them for years and felt like a change.
I'd been and tried on a few pairs at my optician, and on the day I decided to take the plunge I was actually intending to go with a similar style from another brand. Instead, these were on the display next right to them and I made the snap decision that they were it.
Maybe not the best way to evaluate making a big purchase but it worked out this time!
