Optical therapies and devices

An optical therapy device for providing therapeutic light to a nasal cavity of a person, the optical therapy device comprising:

• a body, wherein at least a distal end of the body is configured to be inserted into the nasal cavity and wherein the body is further configured to be hand-held;
• and
• multiple light sources positioned in or on said body, wherein the multiple light sources comprise:
• a first light source capable of emitting optical energy comprising between about 15 percent and about 35 percent of the optical energy provided by the optical therapy device as light in the UVA region of the UV spectrum;
• a second light source capable of emitting between about 1 percent and about 11 percent of the optical energy provided by the optical therapy device as light in the UVB region of the UV spectrum;
• and
• a third light source capable of emitting between about 60 percent and about 90 percent of the optical energy provided by the optical therapy device as light in the visible region of the optical spectrum;
• wherein said device is configured for the at least multiple light sources to be able to emit a dose of UV light toward tissue in the nasal cavity when the distal end of the body is positioned in the nasal cavity.
