The story is I might be going to central Africa next year and I may need to get myself a pair of Balck iridiums, either as a set of lenses for my Flak 2.0 or go creative and customise a new pair of Oakleys. Hopefully next year there maybe more customise options out there. However doing some research one person on trip advisor mentioned people will require a yellow tint lens to block out the UV 400-500 blue light. So in theory I require the Fire Iridium since it contains some sort of yellow tint and is the strongest in it set. In the meantime I'm seeing a lot of Sapphire Iridium glasses and there isn't a lot about them on the internet. So are they worth considering or are blue lenses over rated? I just find it odd they're in every new Oakley frames and there isn't a great deal about them on the web. At the moment I own Black framed Flak 2.0 Grey polarised for driving Black framed Flak 2.0 Bronze Polarised casual Customise Flak 2.0 Jade lens casual Customise Flak 2.0 Prizm Road for running/cycling Customise Flak 2.0 Prizm Track for running/cycling So with owning Bronze and Jade is there any point even thinking about the Sapphire Iridium and the fact I may have to get Fire iridium?
