Methods:A total of 29 emmetropic and myopic subjects (age range: 12\u201318 years) viewed a target in dynamic ambient light (luminance: 5, 100, 200, 500, 1000, 2000 and 3000 lux) and static ambient light (luminance: 1000 lux) at a 40 cm distance with refractive correction. Accommodation and pupil diameter were recorded using an open-field infrared autorefractor and an ultrasound biological microscope, respectively. Results: The changes in the amplitude of accommodative response and pupil diameter under dynamic lighting were 1.01 \u00b1 0.53 D and 2.80 \u00b1 0.75 mm, respectively, whereas in static lighting, those values were 0.43 \u00b1 0.24 D and 0.77 \u00b1 0.27 mm, respectively. The amplitude of accommodation and pupil diameter change in dynamic lighting (t = 6.097, p &lt; 0.001) was significantly larger than that under static lighting (t = 16.115, p &lt; 0.001).The effects of light level on both accommodation and pupil diameter were significant (p &lt; 0.001). Conclusion: Accommodation was positively correlated with light intensity. The difference was about 1.0 D in the range of 0\u20133000 lux, which may lay the foundation for accommodative training through light intervention.<\/jats:p>","DOI":"10.3390\/ijerph191710490","type":"journal-article","created":{"date-parts":[[2022,8,23]],"date-time":"2022-08-23T21:05:12Z","timestamp":1661288712000},"page":"10490","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Is Ocular Accommodation Influenced by Dynamic Ambient Illumination and Pupil Size?"],"prefix":"10.3390","volume":"19","author":[{"given":"Hanyang","family":"Yu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wentao","family":"Li","sequence":"additional","affiliation":[{"name":"Huizhou Third People\u2019s Hospital, Guangzhou Medical University, Huizhou 516000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziping","family":"Chen","sequence":"additional","affiliation":[{"name":"Guangdong Wlight Visual Health Research Institute, Guangzhou 510150, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengzhen","family":"Chen","sequence":"additional","affiliation":[{"name":"Guangdong Wlight Visual Health Research Institute, Guangzhou 510150, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junwen","family":"Zeng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xijiang","family":"Lin","sequence":"additional","affiliation":[{"name":"Educational Equipment Center of Guangdong Province, Guangzhou 510240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1167\/iovs.61.4.49","article-title":"The Complications of Myopia: A Review and Meta-Analysis","volume":"61","author":"Haarman","year":"2020","journal-title":"Investig.
