Lenses were evaluated with three techniques: surface images, Twyman\u2013Green interferometry and focimetry. The carrier lens powers and the spatial distribution, powers and forms of the lenslets were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>MS lenses as manufactured were found to match most of the design specifications provided by their manufacturers, although some apparent small discrepancies were found. The focimeter\u2010measured power of the lenslets was approximately +3.50 D for the MiyoSmart and +4.00 D for the highly aspheric lenslets of the Stellest design. For both lens designs, image contrast would be expected to become modestly reduced in the focal planes of the distance\u2010correcting carrier lenses. Images become much more degraded in the combined carrier\u2010lenslet focal plane, due to the generation of multiple laterally displaced images formed by adjacent lenslets within the effective pupil. The exact effects observed depended on the effective pupil size and its location with respect to the lenslets, as well as the power and arrangement of the lenslets.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Wearing either of these lenses will produce broadly similar effects on retinal imagery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/opo.13191","type":"journal-article","created":{"date-parts":[[2023,6,28]],"date-time":"2023-06-28T10:49:50Z","timestamp":1687949390000},"page":"1125-1136","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Multiple segment spectacle lenses for myopia control.
