A Wood's light examination is done to determine if a skin
condition is caused by a fungal infection. When this special light is directed
toward the skin, certain types of fungi cause the skin to glow or fluoresce
(for example, it may look bluish green under the light).
A Wood's light can
also be used with a special stain to detect eye injuries, and in sexual assault
exams to detect semen on skin or clothing.
