Extra dark sunglasses
In cases where extra protection from light is needed but ML Bilux is not suitable, Multilens can produce lenses that are extremely dark. We can tint lenses to only transmit 1% of the light. It's often a good choice to use polarized lenses and tint them darker. That way, you can also gain benefits from the polarized effect.
Extremely dark lenses also reduces the visual acuity, it's wise not to choose darker lenses than really needed. Therefore it's good to try both ML filter sunglasses and ML Bilux before ordering extra dark sunglasses.
