La normativa específica actual respecto al trabajo con pantallas de visualización de datos (PVD) es resultado de la transposición de la Directiva 90/270/CEE  en el Real Decreto 488/1997, de 23 de abril sobre disposiciones mínimas de seguridad y salud relativas al trabajo con equipos que incluyen pantallas de visualización.
