Tinted Lens is an Ability. Two Pokémon can have this Ability.
Tinted Lens doubles the power of any moves that the Pokémon uses that are "not very effective" against its targets. If a move is regularly not very effective, and thus normally does half damage, it would therefore do normal damage, while a doubly-resisted move (such as a Grass-type move against the Grass/Flying-type Fernling) will do half damage rather than one quarter damage.
Outside of Battle
Tinted Lens has no effect outside of battle.
