Preliminary analyses showed that poorer self - reported vision was consistently related to more functional limitations, feelings of social isolation, and depressive symptomatology and that
poorer visual acuity was related to more functional limitations.
After controlling for the role of sociodemographic variables, poorer self - reported vision was independently associated with more functional limitations, feelings of social isolation, and depressive symptomatology and
poorer visual acuity predicted more functional limitations.
In 2007, researchers reported in the journal Early Human Development that children who had received no DHA in formula or breast milk during the first 17 weeks of life had
poorer visual acuity at age 4, and did worse on language tests showing verbal IQ, than those who fed breast milk.
Reading is a multifactorial process that is influenced by psychological, physiological, environmental, sociological and linguistic factors.1, 2 From an optometrist's perspective, a decrease in reading ability may be associated with
poor visual acuity, unstable binocular vision, or ocular disease.3 It is therefore important that people with poor reading comprehension receive a comprehensive oculo - visual assessment.
Symptoms of DHA deficiency include numbness, tingling, weakness, pain, psychological disturbances, poor cognitive function, difficulty learning, and
poor visual acuity.
Dogs also seem to have
poor visual acuity when compared to humans.
The simple slopes analysis showed that, as expected, visual acuity was unrelated to functional limitations when relationship satisfaction was high (B = − 0.09, t = − 0.29, p = n.s.), but
poor visual acuity significantly predicted more functional limitations when relationship satisfaction was low (B = 0.72, t = 2.54, p <.01).

Performance on the
visual acuity test was coded on a continuum using standard guidelines (Schumm et al., 2009), whereby 20/20 vision or better was coded as «normal or better» vision, between 20/40 and 20/20 was coded as «good» vision, between approximately 20/60 and 20/40 was coded as «moderately decreased» vision, and worse than 20/60 was coded as «
poor» vision.
Based on their performance on the
visual acuity test, 18.8 % (N = 139) had normal or better vision, almost two thirds had good vision (64.6 %, N = 477), 12.1 % (N = 89) had moderately decreased vision, and 4.5 % (N = 33) scored in the
poor vision range.
An examination of the match between the two vision assessments (not reported earlier) showed that 91 respondents whose
visual acuity fell in the moderately decreased to
poor range rated their vision to be good to excellent and an additional 63 respondents whose
visual acuity fell in the normal to good range rated their vision as fair or
poor.
Respondents who were unable to read the largest line on the Sloan chart at 3 m represented
visual acuity worse than 20/200 (N = 4); these individuals were coded to have a score of 20/200 or
poor vision.
The results showed that higher marital satisfaction was a strong buffer of the effects of
poorer self - reported vision on functional limitations and depressive symptomatology and a weaker but significant moderator of the effects of lower
visual acuity on functional limitations.
