Achromatopsia is characterized by the lack of normal "cone vision." Where normal eyes have 6 million cone photoreceptors, located mostly at the center of the retina, achromats have far fewer and rely on "rod vision." Rods do not provide color vision or good detail vision, thus achromat patients are typically totally colorblind or almost totally colorblind, and have poor visual acuity.

Effects of Achromatopsia
(Varying degrees of effects between achromats)

  • Dazzling Glare Sensitivity
  • Discomfort Glare Sensitivity n Colorblindness
  • Poor Visual Acuity
  • Problems adapting to high levels of light causing photophobia in bright lighting.
  • Some photophobia in indoor and low lighting settings.
