Discover if you have Glaucoma

COLOR VISION TEST

This test, also known as Ishihara test, can be positive in the following conditions:

  • Congenital abnormalities of vision perception (e.g. Daltonism, etc)
  • Optic nerve diseases (e.g. optic neuritis, multiple sclerosis)
  • Glaucoma

In these cases, there is reduced ability to discriminate colors, as a result it gets difficult to identify the numbers in the colored pictures attached.
If you have troubles finding the colored numbers in this picture, you should contact an eye doctor.
