‘vision impairment’
‘vision loss’
.
-‘visual impairment’ is a decreased ability to see to a degree that causes problems not fixable by ‘usual means’, such as ‘glasses’-
.
(some also include those who have a decreased ability to see because they do not have access to glasses or ‘contact lenses’)
(‘visual impairment’ is often defined as a best corrected visual acuity of worse than either 20/40 or 20/60)
(the term blindness is used for complete or nearly complete vision loss)
(‘visual impairment’ may cause people difficulties with normal daily activities such as ‘driving’, ‘reading’, ‘socializing’, and ‘walking’)
(the most common causes of ‘visual impairment’ globally are ‘uncorrected refractive errors’ (43%), ‘cataracts’ (33%), and ‘glaucoma’ (2%))
(‘refractive errors’ include ‘near sighted’, ‘far sighted’, ‘presbyopia’, and ‘astigmatism’)
(‘cataracts’ are the most common cause of ‘blindness’)
(other disorders that may cause visual problems include ‘age related macular degeneration’, ‘diabetic retinopathy’, ‘corneal clouding’, ‘childhood blindness’, and a number of infections)
(‘visual impairment’ can also be caused by problems in the brain due to ‘stroke’, ‘premature birth’, or ‘trauma’ among others)
(these cases are known as ‘cortical visual impairment’)
(screening for vision problems in children may improve future vision and educational achievement)
(screening adults without symptoms is of uncertain benefit)
(diagnosis is by an ‘eye exam’)
(the ‘World Health Organization’ (WHO) estimates that 80% of visual impairment is either preventable or curable with treatment)
(this includes ‘cataracts’, the infections ‘river blindness’ and ‘trachoma’, ‘glaucoma’, ‘diabetic retinopathy’, ‘uncorrected refractive errors’, and some cases of ‘childhood blindness’)
(many people with significant ‘visual impairment’ benefit from ‘vision rehabilitation’, ‘changes in their environment, and ‘assistive devices’)
(as of 2015 there were 940 million people with some degree of ‘vision loss’)
(246 million had ‘low vision’ and 39 million were ‘blind’)
(the majority of people with poor vision are in the ‘developing world’ and are over the age of 50 years)
(rates of ‘visual impairment’ have decreased since the 1990s)
.
(‘visual impairments’ have considerable economic costs both directly due to the cost of treatment and indirectly due to decreased ability to ‘work’)
