Is Transitions Gray better than Transitions Brown?
The only difference between the two lenses is personal preference. Both lenses block 100% of both UVA & UVB lighting. Both lenses are as clear indoors as a clear lens and become darker outdoors than any previous technology of Transition. Brown lenses block more blue light thus reducing haze and glare and are more popular in Europe. Gray lenses tend to be more popular in the US and are a good choice for bright conditions.
