Effect of EnChroma glasses on color vision screening using Ishihara and Farnsworth D-15 color vision tests. The prevalence of color vision deficiency (CVD) is about 0.5% in females and 8% in males. Although there is no cure for CVD, specially filtered glasses are purported to improve color contrast. One recent development is the EnChroma filter. The purpose of this study was to assess the effect of the EnChroma filter on color vision screening (CVS) using Ishihara and Farnsworth D-15 color vision tests. The medical records of patients with CVD were reviewed retrospectively. Responses to color vision testing with and without the EnChroma filter were evaluated using Ishihara and Farnsworth D-15 tests, and the overall scores were analyzed. A total of 38 eyes of 19 patients were included. Mean error scores
Feasibility of EnChroma Use in the Emergency Department Setting This study addresses whether the use of EnChroma products are feasible for use in the emergency department by color vision deficient providers. This study addresses whether it is feasible for color vision deficient (CVD) physicians and other healthcare providers to wear EnChroma products in the clinical setting. It is known
accommodate the condition.[1] Special lenses such as EnChroma glasses or X-chrom contact lenses may help people with red–green color blindness at some color tasks,[2] but they do not grant the wearer "normal color vision".[citation needed] Mobile apps can help people identify colors.[2]Red–green color blindness is the most common form, followed by blue–yellow color blindness and total color blindness.[2 is online.[47] * Tinted glasses (e.g. Pilestone/Colorlite glasses) apply a tint (e.g. magenta) to incoming light that can distort colors in a way that makes some color tasks easier to complete. These glasses can circumvent many colorblind tests, though this is typically not allowed.[citation needed] * Glasses with a notch filter (e.g. EnChroma glasses) filter a narrow band of light that excites both the L
