In the wake of the devastating earthquake and tsunami of March 11, our group at Keio University worked diligently to bring the Vision Van, a mobile eye clinic, from Miami, Florida, to disaster areas where medicines, eyeglasses, and indeed all other ophthalmological supplies and services, were nonexistent, thereby assisting many tsunami survivors suffering from eye proble...

In optometry of binocular vision, the question may arise whether prisms should be included in eyeglasses to compensate an oculomotor and/or sensory imbalance between the two eyes. The corresponding measures of objective and subjective fixation disparity may be reduced by the prisms, or the adaptability of the binocular vergence system may diminish effects of the prisms over time. This study inv...

Eyeglasses are a choice for correction for people with regular astigmatism and it doesn’t improve vision for irregular astigmatism. They will contain a cylindrical lens prescription for the astigmatism in a specific meridian of the lens which designates the axis of the lens power. Myopia or hyperopia can be associated to astigmatism. Generally, a single vision lens is prescribed so as to provid...

Retinal stimulation should be considered as a possible treatment for brain injury. Recent research has demonstrated that activating the retina – in particular, the peripheral retina – can influence inputs to the brain in ways that may be useful in rehabilitation. The specific treatment involves designing non-traditional eyeglasses that intentionally alter signaling pathways, rather than simply ...

Abstract This study explores the representation and use of Victorian visual aids, specifically focusing on how design spectacle eyeglass frames shaped ideas ‘normal’ ‘abnormal’ body. It contributes to our understanding assistive technologies in period by showcasing usefulness material evidence for exploring an object was produced perceived. By placing aids their medical cultural context first t...

This article proposes the use of generative adversarial networks (GANs) via StyleGAN2 to create high-quality synthetic thermal images and obtain training data build face recognition models using deep learning. We employed different variants StyleGAN2, incorporating new improved version StyleGAN that uses adaptive discriminator augmentation (ADA). In addition, three databases from literature wer...

This paper investigates a context-adaptive sample acquisition strategy at sub-Nyquist sampling rate for wearable embedded sensor devices. Our approach can be applied to compressive sensing frameworks minimise and transmission costs. We consider context estimate represent the local signal structure feed-forward response model continuously tune of an online system. To evaluate our approach, we an...
