Some horses are extremely sensitive to strong sunlight. Exposure to bright light causes a nerve in the head to send a shock-like sensation to the horse's face, and he reacts by violently flinging his head up and back. This type of head shaking is typically worst in the summer but is also seen on bright winter days.
