Despite the fact that inhabitants of rural areas in low-income countries are most distressed by this, no prior research has studied the impact of poor visual acuity on the economic performance of farms. We conduct a standardized eye test with 288 farm managers in rural Cambodia and find that around 30 percent of our sample suffers from poor visual acuity in terms of nearsightedness (myopia). Our analyses indicate a statistically significant and economically meaningful association of poor visual acuity with economic farm performance. Our results show that gross margins for cropping activities per year could be, on average, around 630 USD higher if farm managers were able to correct for poor vision. Our results suggest that poor visual acuity impairs farm managers from tapping the full potential of their business, which in turn decreases their chance to break the vicious cycle of poverty.<\/jats:p>","DOI":"10.1371\/journal.pone.0274048","type":"journal-article","created":{"date-parts":[[2022,9,9]],"date-time":"2022-09-09T19:28:53Z","timestamp":1662751733000},"page":"e0274048","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["The effect of poor vision on economic farm performance: Evidence from rural Cambodia"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0614-7535","authenticated-orcid":true,"given":"Frederik","family":"Sagem\u00fcller","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Selina","family":"Bruns","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Mu\u00dfhoff","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2022,9,9]]},"reference":[{"issue":"12","key":"pone.0274048.ref001","doi-asserted-by":"crossref","first-page":"e1612","DOI":"10.1016\/S2214-109X(19)30450-4","article-title":"Announcing The Lancet Global Health Commission on Global Eye Health","volume":"7","author":"MJ Burton","year":"2019","journal-title":"Lancet Glob Heal"},{"issue":"5","key":"pone.0274048.ref002","doi-asserted-by":"crossref","first-page":"465","DOI":"10.1080\/17441692.2011.634815","article-title":"An estimation of the worldwide economic and health burden of visual impairment","volume":"7","author":"A Gordois","year":"2012","journal-title":"Glob Public Health"},{"issue":"5","key":"pone.0274048.ref003","doi-asserted-by":"crossref","first-page":"1036","DOI":"10.1016\/j.ophtha.2016.01.006","article-title":"Global Prevalence of Myopia and High Myopia and Temporal Trends from 2000 through 2050","volume":"123","author":"BA Holden","year":"2016","journal-title":"Ophthalmology"},{"issue":"9","key":"pone.0274048.ref004","doi-asserted-by":"crossref","first-page":"e888","DOI":"10.1016\/S2214-109X(17)30293-0","article-title":"Magnitude, temporal trends, and projections of the global prevalence of blindness and distance and near vision impairment: a systematic review and meta-analysis","volume":"5","author":"RRA Bourne","year":"2017","journal-title":"Lancet Glob Heal"},{"issue":"12","key":"pone.0274048.ref005","doi-asserted-by":"crossref","first-page":"e1221","DOI":"10.1016\/S2214-109X(17)30393-5","article-title":"Global causes of blindness and distance vision impairment 1990\u20132020: a systematic review and meta-analysis","volume":"5","author":"SR Flaxman","year":"2017","journal-title":"Lancet Glob Heal"},{"issue":"2","key":"pone.0274048.ref006","doi-asserted-by":"crossref","first-page":"147","DOI":"10.1080\/09286586.2017.1376338","article-title":"Uncorrected and corrected refractive error experiences of Nepalese adults: a qualitative study","volume":"25","author":"H Kandel","year":"2018","journal-title":"Ophthalmic Epidemiol"},{"issue":"9","key":"pone.0274048.ref007","doi-asserted-by":"crossref","first-page":"1736","DOI":"10.1016\/j.ophtha.2013.02.014","article-title":"Utility and uncorrected refractive error","volume":"120","author":"N Tahhan","year":"2013","journal-title":"Ophthalmology"},{"issue":"11","key":"pone.0274048.ref008","doi-asserted-by":"crossref","DOI":"10.1371\/journal.pone.0015431","article-title":"Does cataract surgery alleviate poverty?
