Light therapy is not a recent technique. Since antiquity, Greek Romans treated depression and lethargy with sunlight directed toward the eye.

Polarized light is a light on which is a physical change with a filter, so that electromagnetic waves emitted by a light source to be redirected into a single plan, similar to a laser beam.

Polarization appliances, but with smaller size than those used in clinics, and are sold to us, so that is easy for patients to treat themselves at home. Regardless of how therapy with light provided by such a device can be indicated, you should consult with a specialist before, that will know for sure if your medical history allows you to use this treatment or not.

The light therapy is used in treating depression and psoriasis

Recent studies show that depression – and especially the season one, which appears in the cold season – can be treated by daily exposure to a strong white light.

To treat psoriasis, it is used ultraviolet light from natural sunlight and from artificial source. A treatment called PUVA uses ultraviolet light in combination with drugs that make skin more sensitive to such light. A relatively new technology – Band UVB – which does not prescribe any medicine can be used for a longer period of time than PUVA method.
