The use of conjunctival ultraviolet autofluorescence (CUVAF) as a biomarker of time spent outdoors

Conjunctival ultraviolet autofluorescence (CUVAF) has been used in previous Southern Hemisphere myopia research as a marker for time spent outdoors. The validity of CUVAF as an indicator of time spent outdoors is yet to be explored in the Northern Hemisphere. It is unclear if CUVAF represents damage attributed to UV exposure or dry eye. This cross‐sectional study investigated the association between CUVAF measures, self‐reported time spent outdoors and measures of dry eye.
