Optical diffusers have uses in laser applications and machine vision. Typical fabrication at a commercial level requires master production and the stamping/copying of individual elements at scale. This expensive, indirect process inhibits custom diffusers at reasonable cost. Previously the authors published a novel, direct, single beam method of recording customizable and controllable volume holographic diffusers by manipulating laser speckle and recording the pattern in photopolymer. This method allows for beam-shaping to produce diffusion patterns of various sizes and shapes. In this work, the direct method of recording controllable holographic diffusers is refined to improve diffuser performance (i.e., a decrease in …

Myopia is caused by an eye which has grown too long. The prevalence of myopia has increased drastically in recent years and half of the world’s population is expected to be myopic by 2050.(1) Consequently, a significant increase in sight threatening diseases will follow.(1) Myopia most commonly develops in youth, and we now know that environmental factors affect its development. Nutritional status strongly influences growth and development, including that of the eye. It has been hypothesised, therefore, that nutrition may play a role in this excessive eye growth. Current findings are conflicted, with a clear gap in the evidence.(2,3) Therefore, …
