KOODemos Replacement Lenses(Return to Product Page)

Kind of pricey, but WOW. These are without a doubt the best photochromic lenses I have ever used. Huge range in VLT and they transition really fast. Even in full sun they are really good. I was not expecting them to be this good, but now I might be bringing these along on more rides.

As a total optics nerd I have tried almost every major brand out there, but I always come back to KOO. This lens is no exception. My other fav lens is the fire lens becuase it actually does pretty well in lower light unlike many other red/fire mirror lenses. Def worth a try for MTB or if you have a lot of sun/shade on rides.

I was stoked to be able to pick up a couple of extra lenses for my Demos. Both the clear and photochromatic are excellent. Lens changing is a little more fiddly compared to Smith but not too bad at all. They appear to be pretty tough and scratch resistant, but I am still very careful. Demos do not come with a case so I purchased a cheap hardshell case on Amazon. Works fine. Great glasses.

Easy to switch out the lenses on KOO glasses. These are perfect for the cloudy rainy days in the PNE
