visual skill test

Some of the visual skills Dr. Ni will test for are:

• Tracking: the ability to follow a moving object smoothly and accurately with both eyes, such as a ball in flight or moving vehicles in traffic.
• Fixation: the ability to quickly and accurately locate and inspect with both eyes a series of stationary objects, one after another such as moving from word to word when reading.
• Focus change: the ability to quickly look from far to near and vice versa without momentary blur, such as looking from the chalkboard to a book, or from the dashboard to a street sign.
• Depth perception: the ability to judge relative distances of objects and to see and move accurately in three-dimensional space, such as when hitting a ball or parking a car.
• Peripheral vision: the ability to monitor and interpret what is happening around you while you are attending to a specific central vision task.
• Binocularity: the ability to use both eyes together, smoothly equally, simultaneously and accurately.
