Do I need to tint my lenses darker before sending them to you?

[AR Coating Lab]

You don't have to tint your lenses darker as long as you put them in neutralizer or bleach for about 10 seconds or so to remove any excess dye. Otherwise the excess dye on the lens just makes it appear darker and it will be removed in our cleaning tanks. When that happens there's the possibility that the lens won't come out the color you wanted it to, or that the pair won't match. That's why it;s best to bleach them out a little before you send them so you can see the color they will be.
