Whether or not comorbid vision impairment directly caused the excess disability which cannot be inferred from descriptive data , vision impairment may help identify high-risk individuals or individuals with unmet needs who could be targeted for services and interventions across a variety of other clinical specialties. The impact of vision impairment on people with chronic conditions is explored further later in this chapter. Medical vision aids, which include eyeglasses and contact lenses, are the next largest expense category. The health consequences associated with vision loss extend well beyond the eye and visual system. A higher rate of vision impairment has also been documented for children with Down syndrome Cregg et al. Figure indicates that the costs attributed to eye and vision health increase with age across all payers and that the over population is responsible for the vast majority of expenses for all payers, except private insurance. Irreversible vision impairment resulting from eye disease should be considered a chronic condition; it can amplify the adverse effects of other illnesses and injuries, and people with vision loss commonly live with multiple chronic conditions. It is a great introduction for the general reader into the topic of color vision and its deficiencies, and discusses many different topics related to color blindness. For participants in the Beaver Dam Eye Study, the odds ratio for nursing home placement was 4. While these findings in animals look promising, gene therapy would not be considered for humans until treatments are proven to be safe. People with a vision impairment and other illnesses or conditions are more likely to have difficulty performing tasks and reporting poor health. Your brain then interprets the signals from the cones cells so that you can see the colour of the object.
Language acquisition can also be affected by the loss of vision as active interaction with people and the environment is important in language development. Can come from anyone.
Similar to what was seen in the study of cataract surgery and fractures, the protective association between cataract surgery and mortality was modified by the effects of age and systemic disease burden, where patients who were elderly or who had a moderate burden of systemic disease experienced even stronger protective effects than the overall population.
A range from 9 to 21 percent of adults over the age of 70 possess some degree of DSI Saunders and Echt, The economic impact of vision loss is also substantial. They do it.

Cognition Several studies have found that cognitive impairment is more prevalent and progresses more rapidly in older adults with vision impairment than in those without Lin et al.
The protective association between cataract surgery and fractures may extend beyond a reduction in fracture risk.
Much more rarely, a person may inherit a trait that reduces the ability to see blue and yellow hues. If you have a color vision deficiency, see an eye doctor near you to discuss if color blind glasses are a good choice for you. However, the few studies available that have looked at overall direct and indirect costs found that national costs are in the billions each year and vary substantially by state. This work suggests that some of the functional and affective consequences of vision loss are remediable. Expenditures related to chronic conditions are substantial, with an estimated 66 percent of total health care spending attributable to care for Americans with multiple chronic conditions HHS, In people with vision impairment, the loss of cognitively stimulating activities, such as reading, may diminish other cognitive abilities Lindenberger and Baltes, In addition, vision loss may create difficulties in medication adherence and management e. This study interviewed 17 individuals with co-existing vision impairment and dementia, 17 family caregivers, and 18 vision or dementia health specialists involved in the patients' care Lawrence et al.
