Wash hands before using. Remove the protective cap. Tilt your head back and gently pull the lower eyelid downwards to form a pocket. With the other hand, hold the bottle in an upright position, toward the pocket, and look at the blue tip of the bottle. Gently press the bottle to extract one drop into the eye. Apply one or two drops per eye every three to four hours, or as recommended by an eye care professional. Close your eyes and blink normally. Do not touch the tip of the bottle with your eyes or hands.
