Common Questions

How do online color blindness tests work?

Online tests use pseudoisochromatic plates (like the Ishihara test) where dots of specific colors form numbers that are invisible to people with certain types of color vision deficiency (Protanopia/Deuteranopia).

What is visual memory?

Visual memory describes the relationship between perceptual processing and the encoding, storage, and retrieval of the resulting neural representations. It is tested using pattern recall tasks.

What is contrast sensitivity?

Contrast sensitivity measures your ability to distinguish between an object and its background. Unlike visual acuity (20/20 vision), it assesses the quality of vision in low-contrast situations.

Digital Optometry & Vision Science

Visual processing accounts for a massive portion of the human brain's computational power. Our visual suite moves beyond standard acuity charts to test the quality of your vision.

Key areas of assessment include:

  • Color Vision: Detecting Protanopia, Deuteranopia, and Tritanopia using digital pseudoisochromatic plates.
  • Contrast Sensitivity: The ability to distinguish objects from their background, a key indicator of retinal health.
  • Visual Memory: The capacity of the visuo-spatial sketchpad component of working memory.
