Vision Stations: Addressing Corrective Vision Needs With Low-cost Technologies
نویسندگان
چکیده
Eyeglasses, required for functional vision by nearly half the world's population, are still needed by more than a billion people. There are a number of constraints on the provision of eyeglasses: product cost, durability, and appearance; traditional approaches to evaluating refraction; and sustainably scaling potential distribution methods. We offer our experience with an immigrant population in a US urban setting using a "Vision Station." The station allowed for immediate provision of adjustable glasses using self-refraction, ordering of custom lenses from a low-cost website, and referral to primary and eye care physicians for those with medical eye concerns. As with models in development by other groups, Vision Stations connect people with the life-changing provision of functional vision.

متن کاملInvestigation of the Functional Balance in Children with Sensory Impairment 6 to 14 Years
Aim: The human body is kept in balance by a complicated process including visual, vestibular, and proprioceptive information. Since the postural control systems require information from all three sensory systems in order to achieve or maintain optimal postural stability, the absence of information of one system may have an influence on body sway during balance .The purpose of this study was to ...
