The invention discloses a protective light shield to reduce the harmful effects of resin-curing lights used in dentistry. This is a shield made principally of a single sheet of filtering plastic, shaped in a convenient paddle configuration. The dimension of the filter-paddle is sufficient to block all direct and reflected light from the tooth of the patient that would possibly be seen by any personnel in the operatory. A portion of the paddle is provided with a magnifier which may be employed by the physician for closer inspection of the tooth being operated on. Additionally, a relatively thin intensity-filtering material is applied to the back of the light paddle so that the intensity of the filtered light is reduced for the increased comfort and protection of the physician.
