A dental shield for lessening unwanted hazardous reflections of light in a wavelength band between 400 nm and 500 nm. The dental shield is similar to a traditional shield used on a hand held light delivery device, however the shield is antireflective coated on one or both sides to protect the non-user of the shield the patient, so that harmful reflections into the patients eyes can be lessened. The filter prevents at least 98% of UV or blue light from being reflected.
