This review seeks to determine the prevalence of correctable visual impairment (VI) in older people in the UK, to discover what proportion of these cases are undetected, to suggest reasons for the poor detection and to make recommendations for improving the detection. To establish the context of these issues, the review will also touch on the general prevalence and causes of VI in older people ...

This paper confer the reasons for color vision defects in human eye. This paper also discuss the design and development system for the people who are having problem in their visual system, such as color blindness, low vision, or visual field defects. A new model has been proposed that examine the color vision, vision field defects and visual acuity. Model has proposed that is working on the per...

Deploying large number of cameras with overlapping views for surveillance in large areas such as airports, shopping malls, and elderly care centers is not cost effective. Tracking people using computer vision algorithms in such scenarios involves matching people in non-overlapping camera views. This problem is referred to as Person Re-Identification in the computer vision literature. The import...

This article aims to facilitate optimal management of cataracts and age-related macular degeneration (AMD) by providing information on indications, risk factors, referral guidelines, and treatments and to describe techniques to maximize quality of life (QOL) for people with irreversible vision loss. A review of PubMed and other online databases was performed for peer-reviewed English-language a...

This paper estimates the markup for the Mexican manufacturing sector to detect the impact of trade liberalization on market power. Using Hall’s proposal that states that a procyclical Solow residual is an indication of market power, this research estimates the markup for different periods to detect the change in market power after trade liberalization was implemented. We account for the potenti...

MOST PEOPLE AGREE that stock prices sometimes behave in strange ways. Going beyond this simple observation typically proves more difficult. For at least the past quarter century, economists have been well aware that the variation of stock prices does not nicely match the familiar bell-shaped normal distribution.1 The problem is too many extreme movements. Very large increases or decreases would...

In April 2004, The Eye Disease Prevalence Research Group published a series of articles that included age-specific estimates for the prevalence of low vision and blindness in whites, African Americans, and Hispanics living in the United States. Also included were age-, sex-, and ethnic-specific incidences of the following age-related eye diseases: diabetic retinopathy, macular degeneration, cat...

Vision loss typically affects either the wide peripheral vision (important for mobility), or central vision (important for seeing details). Traditional optical visual aids usually recover the lost visual function, but at a high cost for the remaining visual function. We have developed a novel concept of vision-multiplexing using augmented vision head-mounted display systems to address vision lo...

Low vision can significantly decrease a person's functional ability and independence. With the continuing rise in age of our population, the number of people with low vision will increase substantially. Restoring and maintaining their ability to function independently through the use of specific interventions is an intricate process that calls for the collaboration of various health care profes...
