A vehicle headlight can form a predetermined high-beam light distribution pattern, while being capable of causing the chromaticity of the entire light distribution pattern to fall within a white range (JIS D5500). The vehicle headlight can include: a projection lens that can control light incident on its light incident surface at a first incident position near its optical axis to be directed in a direction not parallel to the optical axis, can control light incident at a second incident position away from the optical axis to be directed in a direction parallel to the optical axis, and can control light incident at an incident position between the first and second incident positions to be directed in a direction closer to the direction parallel to the optical axis as the light is incident at an incident position closer from the first incident position to the second incident position.
