Shades

The Shades perk reduces the effects of signal flares. This is useful in countering enemies who think they have you temporarily blinded, making you a much easier target. This perk is useful for defending in 'Search and Destroy' game mode matches. It is unlocked at level 32.

It cuts the Pink-to-White Hue created whilst within a 5m Proximity of a signal flare.

It has also been seen used in strange ways by PC Gamers, with it becoming a method of communication for players lacking a microphone or headset, in conjunction with written chat.

If the player has Shades equipped, the player model will reflect that, with sunglasses literally on the player model to protect it from the intensity of signal flares.
