An android app that trains your kinetic visual acuity! Kinetic Visual Acuity

3 ways to improve Dynamic and Kinetic visual acuity

◆What is dynamic and kinetic visual acuity?

Dynamic / Kinetic visual acuity is an important factor for athletes.

Static visual acuity is the ability to see a still object.
The visual acuity test using the Landolt ring, which is performed in medical examinations, tests the static visual acuity.

Dynamic and Kinetic visual acuity is the ability to see moving objects.

kinetic visual acuity	in the depth direction

Dynamic visual acuity and Kinetic visual acuity differ greatly in the mechanism of the brain that they perceive. Therefore, the training method is also different.

Sports Vision

There is sports vision as a classification method of visual acuity.

In particular, in baseball hitting, Kinetic and Dynamic visual acuity are most important.

According to the Sports Vision Association, sports vision is classified into the following 8 items.

1.Static vision

Sight to see what is stationary. (Measured by general visual acuity test)

2.Kinetic visual acuity：KVA

Visual acuity for an object that moves in the depth direction.

3.Dynamic visual acuity：DVA

Visual acuity for an object that moves vertically and horizontally.

4.Eye movement

Ability to move the line of sight quickly and smoothly.

5.Contrast sensitivity

Ability to identify subtle differences in brightness.

6.Deep vision (sense of distance)

Ability to recognize relative perspectives.

7.Instantaneous eyesight

Ability to instantly recognize visual information.

8.Eye-hand coordination

Reflexes related to vision.

Dynamic Visual Acuity

Visual acuity for an object that moves vertically and horizontally.

Kinetic Visual Acuity

Visual acuity for an object that moves in the depth direction.

Dynamic visual acuity training method

The most popular method of training Dynamic visual acuity is to read the letters written on the outside signs and telephone poles from the train window.

This training method does not perform vertical training, but it is effective for horizontal training.

The good thing about this training method is that you don’t need to be prepared. You can train any time you are traveling by train.

You can do it from the window of the bus, but when you actually try it, it seems that there are fewer suitable objects than when you do it from the window of the train. “From the train window” is recommended.

Kinetic visual acuity training method

A well-known training method for Kinetic visual acuity is to read the numbers or letters written on the thrown ball.

This method of training is very effective, but it also requires tedious preparations and a pitcher to go out with. It is also difficult to control conditions such as ball speed, rotation speed, and rotation direction.

If the ball speed is too fast or the rotation speed is too high, the training will have no effect, and if it is too slow, it will have no effect.

( It is said that you can train more effectively by using shutter glasses. Shutter glasses are glasses with a flash effect that open and close the shutter at a high speed with a liquid crystal. )

Android app to train Kinetic visual acuity

The training method of writing numbers and letters on the ball is the strongest, but it is not easy, so we recommend using the app as the next best training method.
