Abstract
Using of BIOPTRON devices under home conditions becomes more and more frequent, which is related to a more common application of phototherapy in general. Phototherapy, similarly of other methods of physical therapy, has its specific indications and contra-indications.
Because of a high level of safety, there is no generally accepted opinion on real contra-indications for irradiations with polarized light. In some cases, dangers related to its application are overestimated (mostly by physicians), whole sometimes (under home conditions) they are underestimated.
Contra-indication for using of polarized light as a curative factor have been worked out in detail, and their four groups (well-substantiated, limiting, acceptable, and erroneous) have been classified.
