Most existent models of the lens deal with its external shape independently of the refractive index and, subsequently, through optimization processes, adjust the imaging properties. In this paper, we propose a physiologically realistic GRIN model of the lens based on a single function for the whole lens that accurately describes different accommodative states simultaneously providing the corresponding refractive index distribution and the external shape of the lens by changing a single parameter that we associate with the function of the ciliary body. This simple, but highly accurate model, is incorporated into a schematic eye constructed with reported experimental biometric data and accommodation is simulated over a range of 0 to 6 diopters to select the optimum levels of image quality. Changes with accommodation in equatorial and total axial lens thicknesses, as well as aberrations, are found to lie within reported biometric data ranges.<\/jats:p>","DOI":"10.1364\/boe.386459","type":"journal-article","created":{"date-parts":[[2020,5,8]],"date-time":"2020-05-08T18:00:07Z","timestamp":1588960807000},"page":"3699","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Single function crystalline lens capable of mimicking ciliary body accommodation"],"prefix":"10.1364","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0911-2343","authenticated-orcid":true,"given":"A.","family":"Jaimes-N\u00e1jera","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2399-3661","authenticated-orcid":true,"given":"J.
