Color Vision Quiz Application

application Color Vision Quiz
Even though color vision deficiencies are quite common they are not highlighted enough which is why the Pro Visu Foundation wants to provide people, affected by these disorders, an application that allows them to :
  • estimate their level of color vision using the Ishihara test questionnaire.
  • allow the general public a chance to see from the perspective of patients suffering from eye disorders, through the use of a simulator.
  • access to quality information about color vision disorders.
