Oakley L-Frame with Clear Lens included MX Goggles,L Frame Frame/Grey & Clear AF Lens,one size

Q: is the product with the gray lenses? is the model the mx sand that is for use over glasses? thank u

The ones I purchased have the grey lens and they fit quite well over my glasses.

Q: How do you change the lens on these goggles? I can't seem to figure it out and it came with no instructions.

There are youtube videos showing how to do this or you can google it. Really isn't hard to do once you find the trick to it. The lens sits in a slot in the frame. I find that removing the lens from the top of the goggle frame first and working around to the nose area last and reverse this (nose first) while installing works best for me. Hope that helps some.
