Debate continues as to whether their mechanism of action is due to through\u2010focus effects or to the image contrast changes due to the inclusion of the lenslets. This study explores the second possibility by modelling the performance of a combined MS lens\u2010eye optical system in terms of its modulation transfer function (MTF) under various conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The optical design program Ansys Zemax OpticsStudio was used to determine distance MTFs for the combination of either a single\u2010vision or a Hoya MiyoSmart MS lens with a 4 D myopic eye model. Conditions included axial and peripheral objects with co\u2010axial lens and eye, and rotating the eye away from the lens axis to observe objects through the lenslet\u2010covered region of the lens. Visual resolution under each condition was estimated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Observing objects through the lenslet array lowered modulation transfer in comparison with that given by the single\u2010vision lens, especially as spatial frequency increased. In peripheral observation at a field angle of approximately 32.5 degrees, imagery was poor. Foveal image quality was better with axial viewing through the clear MS lens centre than when the eye was rotated by approximately 30 degrees.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Optimal visual resolution during MS lens wear is achieved when fixating through the clear, central area of the lens. Under these circumstances, objects at 20\u201350 degrees from fixation are seen through the lenslet\u2010covered region of the carrier which produces a low\u2010pass spatial frequency filtering effect. Here, visual resolution is limited to a few cycles per degree so that any growth control mechanism must rely on low spatial frequency information.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/opo.70016","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T13:00:13Z","timestamp":1758114013000},"page":"1912-1923","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Myopia control and modulation transfer functions for multisegment spectacle lenses"],"prefix":"10.1007","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6406-2479","authenticated-orcid":false,"given":"W.
