  • Keep wood furniture and upholstery away from direct sunlight. Draw blinds or curtains during the brightest part of the day.
  • Display light-sensitive objects and art in darker areas of the home.
  • Frame your photographs or paintings with glass or Plexiglas designed to filter harmful ultraviolet rays.
  • Minimize exposure for light-sensitive display objects by giving them a rest in the dark from time to time.
