• lens
  • Distance vision corrections are made by re-adjusting the lens for distance, instead of by tilting and/or rotating the head to view object through the best part of the lens for the distance. (wikipedia.org)
  • modern semi-rimless eyewear features lenses partially secured inside of a half-frame, with the lower portion of the lens held in place by nylon wire. (wikipedia.org)
  • people
  • The American Foundation for the Blind removes barriers, creates solutions, and expands possibilities so people with vision loss can achieve their full potential. (afb.org)
  • color
  • To compare chromatic VEP response to isoluminant red-green stimulus in children with congenital red-green color deficiency with a control group of 30 children with normal color vision. (arvojournals.org)
  • 10 children (8-16 years) with congenital color vision deficiency (7 in deutan and 3 in protan axis) and 30 healthy children (7-19 years) were included in the study. (arvojournals.org)
  • Color vision was assessed with Ishihara plates, Farnsworth-Munsell hue 100 test and Farnsworth-Munsell D-15 test. (arvojournals.org)
  • The positive wave was recorded in 90 % (9/10) of children with color vision deficiency and in all children from the control group. (arvojournals.org)
  • Furthermore, children with color vision deficiency did not show age-dependent linear decrease of the positive wave latency as was observed in the control group. (arvojournals.org)
  • VEP response to isoluminant chromatic stimulus showed different features in children with congenital color vision deficiency compared to children with normal color vision. (arvojournals.org)
