This study aimed to examine the impact of occupational exposure to low-frequency electromagnetic fields on cataract development. Methods: One hundred employees of Zahedan Electricity Company participated in this study. They were assigned to four groups based on their level of exposure: regular, operational, operator personnel, and non-exposure. Based on LOCS III grading, the risk of developing different types of cataracts (i.e., nuclear, posterior subcapsular, and cortical) was evaluated for all participants. Results: The frequency of cataracts was 62.2% in the exposure group (which includes three subgroups: the regular, operational, and operator personnel) and 53.8% in the non-exposure group. There was a significant difference between the study groups in terms of nuclear opacity grading (P = 0.003). The correlation between nuclear and posterior subcapsular cataract grading and work experience duration in the exposure group was statistically significant (P &lt; 0.018). Conclusion: This study\u2019s findings indicate that exposure to low-frequency electromagnetic fields such as power lines, power plants, and power distribution posts may be a risk factor for cataract development, particularly nuclear cataracts.<\/jats:p>","DOI":"10.18502\/jovr.v20.12281","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T08:42:24Z","timestamp":1745570544000},"page":"1-6","update-policy":"https:\/\/doi.org\/10.18502\/knecrossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Effect of Occupational Exposure to Low-frequency Electromagnetic Fields on Cataract Development"],"prefix":"10.18502","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0909-8257","authenticated-orcid":false,"given":"Mohammad Hosein","family":"Validad","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9455-0721","authenticated-orcid":false,"given":"Monireh","family":"Mahjoob","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masoud","family":"Pishjo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mostafa","family":"Diani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4733-3422","authenticated-orcid":false,"given":"Tahereh","family":"Rakhshandadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7770","published-online":{"date-parts":[[2025,4,25]]},"container-title":["Journal of Ophthalmic and Vision Research"],"original-title":[],"link":[{"URL":"https:\/\/knepublishing.com\/index.php\/JOVR\/article\/download\/12281\/28725","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/knepublishing.com\/index.php\/JOVR\/article\/download\/12281\/28726","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/knepublishing.com\/index.php\/JOVR\/article\/download\/12281\/28725","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T06:50:09Z","timestamp":1756277409000},"score":1,"resource":{"primary":{"URL":"https:\/\/knepublishing.com\/index.php\/JOVR\/article\/view\/12281"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,25]]},"references-count":0,"URL":"https:\/\/doi.org\/10.18502\/jovr.v20.12281","relation":{},"ISSN":["2008-322X","2008-2010"],"issn-type":[{"value":"2008-322X","type":"electronic"},{"value":"2008-2010","type":"print"}],"subject":[],"published":{"date-parts":[[2025,4,25]]}}}
