The aim of this study was to validate a novel visual triage test for dentists that is easy to use and freely available. The near visual acuity at 300 mm of 106 dental professionals (aged 21\u201365 years) was assessed with 1) a validated near visual test for scientific purposes miniaturized on a microfilm; 2) an experimental test using a US $5 bill, in which the first five words of each line in the Lincoln Memorial frieze had to be read under a dental operating light. The Spearman rank correlation coefficient of 0.784 revealed a strong correlation between the two tests (p&amp;lt;0.0001). The ability to read six or more words in the memorial frieze meant there was a 94% chance of having a validated near visual acuity greater than or equal to the median score of the dentists tested. If none of the words could be read, the chance of having a near visual acuity below the median of the peer group was 89%. The influence of the dentists' age and experience on their visual performance reported in former studies was corroborated with this new test. The US $5 bill offers a simple and easily available near visual test to rank individuals' near vision relative to that of other dentists and to recognize the progression of presbyopia with increasing age.<\/jats:p>","DOI":"10.2341\/16-128-l","type":"journal-article","created":{"date-parts":[[2017,7,14]],"date-time":"2017-07-14T11:16:06Z","timestamp":1500030966000},"page":"581-586","source":"Crossref","is-referenced-by-count":8,"title":["A Near Visual Acuity Test for Dentists"],"prefix":"10.2341","volume":"42","author":[{"given":"P","family":"Perrin","sequence":"first","affiliation":[{"name":"Philippe Perrin, Dr med dent, Department of Preventive, Restorative and Pediatric Dentistry, University of Bern, Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Eichenberger","sequence":"first","affiliation":[{"name":"Martina Eichenberger, Dr med dent, Department of Preventive, Restorative and Pediatric Dentistry, University of Bern, Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KW","family":"Neuhaus","sequence":"first","affiliation":[{"name":"Klaus W.
