This book was released on 2018-02-08 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Effect of Illumination on Peripheral Vision The outcome was negative. It seemed, however, that the most favorable conditions required had not been secured; and further tests were therefore necessary. The present study was undertaken largely for the purpose of furnishing such supplementary tests. It was thought, moreover, that further work might throw light on certain irregularities in F ernald's general results. We undertook, therefore, to repeat Fernald's experiments, with additional variations, under exactly duplicate conditions. After our experiments had been completed and put in what then seemed final form, a paper appeared3 in which Fernald's theses were attacked from a new direction. Rand and Ferree now declared that instead of selecting the most favorable conditions for her phenomena - colored after-images from colored stimuli sensed as colorless - Fernald had chosen the very worst. They were unable to confirm the results that she obtained in the Bryn Mawr and Chicago laboratories; i. E., they, failed (as a rule) to get the anomalous colored after images, when a white background was used. On the other hand, they were able, if they used a black background, pre fixation ground, and projection ground, to secure these anoma lous after-images practically in every trial.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of dark adaptation of light leaking around the edges of a spectacle frame worn under ambient light levels of 0.4 and 15 foot-Lamberts for 0.5 to 5 minutes were measured. Younger observers were virtually unaffected by light leaks in ambient illumination of 0.4 fL. However, after 5 minutes in ambient illumination of 15 fL, they required about 45 seconds to recover complete dark adaptation, and observers over the age of 40 required nearly three minutes. Originator-supplied keywords include: Night vision and Effect of peripheral vision on dark adaptation.

This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Available in PDF, EPUB and Kindle. Book excerpt: When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.
