Purpose: To assess the efficacy of Defocus Incorporated Multiple Segments (DIMS) spectacle lens for myopia control and its impact on vision-related quality life in Chinese children over a 1-year period. Methods: This randomized double-blind prospective controlled clinical trial enrolled 176 myopic subjects aged between seven 14 years who were randomly assigned into DIMS group or single-vision (SV) group. Refractive error axial length measurements at baseline, three-, six-, nine-, 12-month...
Abstract Integral imaging has three display modes including real mode, virtual and focused each mode unique characteristics. In this paper, the accommodation responses to three‐dimensional (3‐D) targets reconstructed by of integral were measured statistically analyzed. Through least square method, standard deviation analysis, t ‐test we found that 3‐D target was more similar on same depth position. Moreover, closer central plane was, steadier response could provide. These statistical...
Changes in vision that occur normal healthy aging can be seen fundamental measures of monocular vision. However, the nature changes binocular with age remain unclear. A total 28 older (53-66 years) and younger adults (20-31 were enrolled this study. We performed a battery tests to assess differences contrast thresholds various visual functions including dichoptic masking weight strength, balance point for fused stimuli, stereoacuity control groups. Aging significantly increased (p < 0.001)....
Transmission and processing of sensory information in the visual system takes time. For motion perception, our brain can overcome this intrinsic neural delay through extrapolation mechanisms accurately predict current position a continuously moving object. But how does behave when abruptly changes prediction becomes wrong? Here we address question by studying perceived object with various abrupt human observers. We developed task which bar is monotonously horizontally, then suddenly stops,...
Purpose: The mammalian brain can take into account the neural delays in visual information transmission from retina to cortex when accurately localizing instantaneous position of moving objects by motion extrapolation. In this study, we wanted investigate whether such extrapolation mechanism operates a comparable fashion between eyes normally sighted and amblyopic observers. Methods: To measure interocular extrapolation, adapted dichoptic version flash-lag effect (FLE) paradigm, which...
Purpose: It has been suggested that amblyopes present impaired motion extrapolation mechanisms. In this study, we used the flash grab effect (FGE), illusory mislocalization of a briefly flashed stimulus in direction reversing moving background, to investigate whether amblyopic visual system can correct overextrapolation. Methods: Thirteen and 13 control subjects participated experiment. We measured monocular FGE magnitude for each subject. Two spatial frequency (2 8 cycles), two texture...
