The role of astigmatism in myopia development, myopia progression and myopia control Open
Aims/Purpose Myopia arises primarily due to excessive axial elongation and is associated with an increased risk of ocular complications and visual impairment, particularly in high myopia. Although astigmatism may have implications on refra…

Defocus Incorporated Multiple Segments (DIMS) spectacle lenses in <span>UK</span> children: Outcomes from a 2‐year multi‐site interventional trial Open
Introduction Myopia is a growing public health concern with long‐term risks for visual impairment. While Defocus Incorporated Multiple Segments (DIMS) spectacle lenses have proven efficacy in Chinese children, evidence from Western populat…

High myopia: Reviews of myopia control strategies and myopia complications Open
Background Myopia and especially high myopia are recognised as major public health concerns. Although the prevalence of high myopia in young children is low, 10–20% of high school children in Asia have high myopia, with many still progress…

Age-matched analysis of axial length growth in myopic children wearing defocus incorporated multiple segments spectacle lenses Open
Background/aims Defocus incorporated multiple segments (DIMS) spectacle lenses are known to be able to inhibit axial length (AL) growth in myopic children compared with single vision (SV) spectacle lenses. However, it is not known whether …

Assessment of Visual Quality Improvement as a Result of Spectacle Personalization Open
Personalized spectacles customized according to an individual’s facial anatomy were developed to provide enhanced visual performance and overall comfort when compared to standard spectacles. In this comparative crossover trial, each subjec…

Effects of Lens-Induced Astigmatism at Near and Far Distances Open
The better tolerance to lens-induced astigmatism blur at near than at far distance in photopic conditions with HC stimuli is tentatively attributed to a possible experience-mediated neural compensation associated to the tendency of the eye…

Improvement or Worsening of Human Contrast Sensitivity Due to Blue Light Attenuation at 450 nm Open
In the choice of a blue-filtering lens, practitioners should take into consideration that the attenuation of light in the range 420-470 nm is expected to produce a CS worsening in subjects showing a relatively high initial CS (higher than …
