Over 600 swimmers at the public pools in Styria, Austria had their eyes examined for freckles and filled out a questionnaire that asked about their lifetime sun exposure and sun-protection habits. Resultantly, researchers found out that the development of eye freckles correlated with increasing age, lifetime number of sunburns and a history of severe sunburns resulting in blisters.
The journal quoted in its conclusion, "The association of iris freckles, behavioral factors, and dermatologic findings, as well as the topographical distribution, indicate that sunlight exposure may trigger the formation of eye freckles. Furthermore, the evaluation of iris freckles could also be helpful in understanding the role of sunlight in several ophthalmologic diseases." Researchers also found out that freckles were most commonly found in lower outer quadrant of each eye.
