Low Vision, Vision Disability, and Blindness

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Low vision refers to impairment of vision that cannot be corrected medically, surgically, or by refractive means. However, most definitions of low vision and blindness, which are used to determine eligibility for low vision rehabilitation and registration for disability benefits, are based on visual acuity or extent of the visual field, potentially underestimating the impact of vision loss on health, functioning, and quality of life. The prevalence of visual impairment increases with age, and as populations across the globe age, the number of persons with low vision and blindness is expected to increase. The impact of visual impairments goes beyond vision, as low vision affects the ability to carry out many activities of daily living, including reading and driving, which play an important role in maintaining independence and quality of life. Vision contributes substantially to functioning, safety, and well-being in older adults, and therefore, low vision has the potential to exacerbate declines in health and functioning as individuals age. Therefore, low vision rehabilitation, in tandem with social support and environmental modifications, is important to enhance the health, functioning, well-being, and participation in society of individuals with low vision. This chapter highlights the impact of low vision on function and the importance of vision in maintaining independence and preserving quality of life, especially among older adults.
