| Summary: |
The aim of this article
was to discuss one of the attributes of the sight organ
– the eye adaptation capacity to the various light
conditions and to provide the factors, that may cause
disorders of this visual function course.
The article presents the definition and physiological
mechanism of eye adaptation. The dependence of
adaptation course on existing light conditions (distinguishing
dark and light adaptation and taking into account the
glare phenomenon) was discussed. Possible, clinical
reasons of deterioration of eye adaptation capacity were
also listed.
In conclusion, the possibility to use the examination of
eye adaptation capacity in diagnosis (e.g. to state or
monitor the development level of eye diseases and some
of systemic diseases) or certification (e.g. to certify
occupational usefulness) was emphasized. |
