According to researchers:
- The findings showed that eye freckles could indicate the presence or risk of sunlight-triggered eye diseases.
- These diseases include cataract or macular degeneration.
- Furthermore, the development of eye freckles also correlated with increasing age.
- Number of sunburns and a history of severe sunburns may result in blisters, the researchers reported.
- “While we do not know the exact role of sunlight in several eye diseases, we now have a biomarker (iris freckles) indicating high amounts of chronic sunlight exposure,” said an ophthalmologist
- In addition, people with dark colored eyes were found less likely to have eye freckles.
- Furthermore those who maintained better sun protection habits like using sunscreen or covering up are also less likely to have freckles.
- Over 600 swimmers at public pools had their eyes examined for freckles.
- Furthermore they also filled out a questionnaire that asked about their lifetime sun exposure and sun-protection habits.
- Researchers also found that freckles were most commonly found in the lower outer quadrant of each eye.
- This may be because the eyebrow and nose shield the upper and inner quadrants of the eye from the sun.
- In addition it lowers the exposure and the risk of developing freckles.
