Abstract: Aging is associated with the accumulation of misfolded and damaged proteins. This accumulation is the result of an imbalance of proper protein folding, maintenance, and disposal. Maintaining proteostasis is critical to the health and life of an organism. While studies consistently observe that the proteostasis network diminishes with age, the effects on individual mechanisms have not ...

PURPOSE To investigate the influence of color vision on myopia development by testing refraction error and axial length of the eye for high school students with and without color vision deficiency (CVD). METHODS A school-based cross-sectional, cluster sample study was conducted to test the color vision and refractive error of 16,539 high school students. Students were screened for CVD using a...

Liquid crystal displays (LCD) are currently replacing the previously dominant cathode ray tubes (CRT) in most vision science applications. While the properties of the CRT technology are widely known among vision scientists, the photometric and temporal properties of LCDs are unfamiliar to many practitioners. We provide the essential theory, present measurements to assess the temporal properties...

The importance of including an adequate test for the discovery of deficiencies in color vision in any thorough medical examination of students has long been recognized; it is obviously desirable to detect at an early age those individuals who will be excluded from pursuing careers in occupations which require good color perception. For several years the Ishihara color vision test was used as pa...

This paper is a review of the literature surrounding the potential impact of undiagnosed and untreated refractive vision problems on reading development in the early years of primary school. Despite pre-school screening programmes, it is still possible for children to enter school with undiagnosed or uncorrected refractive vision problems. This paper generally discusses correlations between ref...

The unique physical constraints of mobile devices pose significant usability and accessibility challenges, especially to people with vision deficiencies. Adapting existing website content to improve usability and accessibility has become an important issue. This research aims to reduce the difficulties encountered by mobile web users with an integrative adaptation approach, called PRECMAS, impl...

Visually impaired is a common problem for human life in the world wide. The projector-based AR technique has ability to change appearance of real object, and it can help to improve visibility for visually impaired. We propose a new framework for the appearance enhancement with the projector camera system that employed model predictive controller. This framework enables arbitrary image processin...

Genetic analyses were performed on five male children (approximately 3 years), two suspect color-normals and three suspects for congenital color vision deficiencies. These classifications were based on visually-evoked potential (VEP) responses to M- and L-cone-isolating stimuli obtained in a previous study when each subject was either 4- or 8-weeks old. The present analyses were performed in a ...
