Low order ocular aberrations were measured with a Hartmann\u2013Shack aberrometer in a sample of 28 young emmetropic subjects. A stationary Maltese cross was presented at 2.5 D and 5.0 D of accommodative demand and at 0\u00b0, 10\u00b0 and 20\u00b0 of eccentricity in the horizontal visual field under two different illumination conditions (white and red light). Wavefront data for a 3 mm pupil diameter were analyzed in terms of the vector components of refraction (M, J0 and J45) and the relative peripheral refractive error (RPRE) was calculated. M was myopic at both accommodative demands and showed a statistically significant myopic increase with red illumination. No significant change in J0 and J45 was found with accommodation nor between illumination conditions. However, J0 increased significantly with eccentricity, exhibiting a nasal-temporal asymmetry. The RPRE was myopic at both accommodation demands and showed a statistically significant hyperopic shift at 20\u00b0 in the nasal retina. The use of red light introduced statistically and clinically significant changes in M, explained by the variation of the ocular focal length under a higher wavelength illumination, increasing the experimental accommodative demand. These findings may be of relevance for research exploring peripheral refraction under accommodation, as the choice of target illumination is not trivial.<\/jats:p>","DOI":"10.3390\/photonics9050364","type":"journal-article","created":{"date-parts":[[2022,5,24]],"date-time":"2022-05-24T03:16:55Z","timestamp":1653362215000},"page":"364","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Effect of Accommodation on Peripheral Refraction under Two Illumination Conditions"],"prefix":"10.3390","volume":"9","author":[{"given":"Raquel","family":"van Ginkel","sequence":"first","affiliation":[{"name":"School of Optics and Optometry of Terrassa, Universitat Polit\u00e8cnica de Catalunya, BarcelonaTech, Violinista Vellsol\u00e0 37, 08222 Terrassa, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7062-7595","authenticated-orcid":false,"given":"Mar\u00eda","family":"Mech\u00f3","sequence":"additional","affiliation":[{"name":"Clinical and Experimental Optometry Research Lab (CEORLab), Center of Physics, School of Sciences (Optometry), University of Minho, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4770-8992","authenticated-orcid":false,"given":"Genis","family":"Cardona","sequence":"additional","affiliation":[{"name":"Optics and Optometry Department, Universitat Polit\u00e8cnica de Catalunya, BarcelonaTech, Violinista Vellsol\u00e0 37, 08222 Terrassa, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9050-4170","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"Gonz\u00e1lez-M\u00e9ijome","sequence":"additional","affiliation":[{"name":"Clinical and Experimental Optometry Research Lab (CEORLab), Center of Physics, School of Sciences (Optometry), University of Minho, 4710-057 Braga, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1038\/519276a","article-title":"The myopia boom","volume":"519","author":"Dolgin","year":"2015","journal-title":"Nature"},{"key":"ref_2","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":"Holden","year":"2016","journal-title":"Ophthalmology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1489","DOI":"10.1136\/bjo.2005.071118","article-title":"Eye growth changes in myopic children in Singapore","volume":"89","author":"Saw","year":"2005","journal-title":"Br.
