You just need to open the lever on the left side of the goggle, lift the lens on the side of the lever to free it, and there you go: you're done.
The Open is available with two Zeiss lenses, one for sunny days and one for bad weather conditions.
In alternative, you can choose to have it with the awesome The One photochromic and polarized lenses that are designed to work well in all conditions.
