The advantages of caring for your eyes are outlined, as well as what could happen if your eyes are subjected to infection. The intertitle "Good eyesight: the birthright of every child", is illustrated by shots of children playing in a sandpit and playing on a horse and cart. Intertitle "Good eyesight: the joy of the game", is illustrated by young men playing Americal football. Intertitle "Good eyesight: a comfort in the evening of life", is illustrated by an elderly couple sitting in the living room in the evening, reading and sewing. The intertitles describe blindness as a tragedy and we are shown a toddler with poor eyesight, children reading braille in a blind school and a blind cobbler at work. Blindness, according to the film, is a tragedy because it is preventable, especially if we understand how fragile the eye is, particularly the eye of a child. The film explores the structure of the eye which is described as being similar to a camera. Drawings of a camera and an eye are placed side by side and contrasted. Further diagrams describe the difference between long- and short-sightedness.
