In these pics, both lens are supposed to be a fire a frame lens, but they look different.
Is this the "batch variation" at work again?

Or, just lighting?

Or, they are truly different colors?


Example 1



Example 2

Could be either of those factors you mentioned or both.

On sunglasses, the batches usually are less different then on bigger frames, like M frames or goggles.

The lens I won came in today and I installed it. I am so glad I got it as it is night and day darker than my other fire a frame lens...left old fire, right new fire lens
