Description:

  • Your cornea, pupil, and lens work together to focus light on your retina.
  • If your eyeball is too long or too short, you will have blurry vision.
  • EyeQue vision testing solutions incorporate Inverse Shack-Hartmann technology and measure your vision through game-like exercises.
  • This technology utilizes optical lenses, combined with smartphone’s pixel movement, to measure where the light focuses is the back of your retina.
  • When people administer the EyeQue vision test, they adjust two lines, red and green, until they merge into one solid yellow line, indicating light focus on the retina.
  • EyeQue’s cloud database analyzes your information and provides personalized EyeGlass Numbers® that enable you to order glasses from select online retailers.
