Among these, two new techniques were introduced: an electronic push\u2010up and a minus lens technique with a tunable lens. Three repeated measurements were performed with each method. The repeatability limit and non\u2010parametric Bland\u2013Altman analysis were used to describe the repeatability and agreement of each method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The repeatability limit was between \u00b10.7 D and \u00b11.4 D for the minus lens techniques, around \u00b11.8 D for the push\u2010up methods and \u00b11.4 D for the objective procedure. The largest differences in median values were found between the push\u2010up and objective methods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Push\u2010up methods are most likely to overestimate accommodation, while the objective method gives the lowest results. New techniques show good repeatability for measuring the amplitude of accommodation. Among the subjective methods, the minus lens technique with the tunable lens gives the best repeatability, is one of the fastest and gives results most similar to the objective method.<\/jats:p>\n
