[{"role": "system", "content": "Visual impairment, also known as vision impairment or vision loss, 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.\n"}, {"role": "assistant", "content": "I have major vision loss and even my glasses now do not help."}, {"role": "user", "content": "I have bad vision as well, I just wear glasses and contacts, I am sorry you are struggling with it"}, {"role": "assistant", "content": "Yes it is crazy in this day and age that people do not have access to glasses or contact lenses."}, {"role": "user", "content": "That is hard to imagine, I take that for granted every day, but they are expensive, that is a luxury"}, {"role": "assistant", "content": "Yes anyone with less that 20/20 is pretty much having a bad visual impairment."}, {"role": "user", "content": "I am nowhere near that, so I am very fortunate to have glasses, I like contacts too for how I look, but they are annoying to deal with"}, {"role": "assistant", "content": "Some of the most common causes of visual impairments are cataracts and glaucoma."}, {"role": "user", "content": "I know a few people with Glaucoma, it does not seem to be a fun disease, but I am not sure exactly what it is"}]
