How Strobe Sport Training Glasses Work

A stroboscope is an instrument used to make a cyclically moving object appear to be slow-moving or stationary.

In its simplest form, a rotating disc with evenly-spaced holes is placed in the line of sight between the observer and the moving object.

The rotational speed of the disc is adjusted so that it becomes synchronized with the movement of the observed system, which seems to slow and stop.

The illusion is caused by temporal aliasing, commonly known as the stroboscopic effect.

In electronic versions, the perforated disc is replaced by a lamp (or LED) capable of emitting brief and rapid flashes of light.

The frequency of the flash is adjusted so that it is an equal to, or a unit fraction below or above the object's cyclic speed, at which point the object is seen to be either stationary or moving backward or forward, depending on the flash frequency.

Our Strobe Glasses are equipped with high speed LCD (liquid crystal display) controlled by CPU (Central Processing Unit) instead of a flash lamp or LED.

You may have experienced a stroboscopic effect in a theater or a discotheque, allowing you to see very fast moving objects or dancing as if they were in slow motion. You can now experience that effect, not through a normal stroboscope lamp system but through the world's fastest LCD shutter system. No toy, our patented technology provides you the opportunity to employ this effect to improve your dynamic vision and sport vision easily, hand-free, whenever and wherever you wish.

When you use our glasses, you can see when the LCD is on, i.e., a lens is transparent but you cannot see when LCD is off, i.e., a lens is closed or not transparent.

By blinking LCD in front of your eyes, you can get stroboscopic effect very easily anywhere and anytime as you wish.

Of course, frequency is adjustable as same as electronic stroboscopes.

In addition to that, duty ratio or on/off ratio of each cycle is also adjustable.


Frequency

Our frequency Adjustment LCD shutter lenses repeat transparent (open) and opaque (closed) continuously. To change this speed, you merely use the frequency adjustment. The frequency is adjustable 1Hz to 200Hz, every 1Hz.

It is more effective to adjust the frequency higher in order to see a ball's rotation or orbit and lower to carry sport vision enhancement training.

With higher frequency

More suitable to see a ball's rotation or orbit.

With lower frequency

More suitable for sport vision enhancement training.

Duty Ratio

Duty Ratio Adjustment

Duty Ratio refers to the percentage not visible in each blinking cycle.

Normal stroboscope lighting has no function to adjust the duty ratio.

To change this percentage on our glasses, merely employ the duty ratio adjustment.*

The Duty Ratio is adjustable 30% to 90%, adjustable in 5% increments.

It is more effective to adjust the duty ratio higher to see a high speed object and lower to see one which is low speed.

Higher Duty Ratio

With higher duty ratio it is more suitable to see a high speed object but the vision becomes darker.

Lower Duty Ratio

With a lower duty ratio you are better able to see a lower speed object to check the stream of that with tails.

*The proper adjustment of frequency and duty ratio depend on a kind of sports and each individual.

How do we see things? Why should dynamic vision be improved?

When we see things, the image of objects is first caught by our eyes and reflected on our retinas. It is then sent to our brain through our optic nerves as an electric signal which is recognized as an image. It is thus that we are able to see things. As it takes time, it causes a so-called "delay of perception." In the case of moving objects, it takes 0.5 to 0.6 seconds.

When we play sports, such as, baseball, cricket, tennis, or football, a ball might move over 150km/h. In motor sports, a machine's running speed can exceed more than 300km/h. When you engage in martial arts, you have to react against your opponent in front of you as possible.

On the other hand, our walking speed is normally 3 to 5 km/h and running speed is 20 to 30 km/h. Our perception is effective to that level of speed in our daily life but not enough to play most sports. Considering the delay of perception, the athlete, be they amateur or professional, has to train and improve their dynamic vision in order to achieve peak performance.

Pitching machines for baseball or service machines for tennis, for example, may be employed for daily practice in their respective sports. The faster the ball speed becomes, the more difficult it becomes for players to react. Though this helps the players to become better accustomed to the ball speed, it does little to develop their dynamic vision.

The Stroboscopic effect

When you see a moving object under the strobe light, you can distinguish the object image only when the strobe light flashes. This is because a continuous moving image is sliced into multiple still images. It also means that the visual information entering into the eyes is restricted. The brain has to compute the given information and create images during the blackout period in order to compensate for the rest of images.

It has been known many years that the strobe effect helps to improve sports vision dynamically. Up to now, however, the stroboscope devices have failed to live up to their promise, for a number of reasons:

  1. They have neither been compact nor portable
  2. They have been prohibitively expensive
  3. Their use has been limited to a dark room and were not applicable directly in the field
Dynamic Vision Primary Strobe Glasses

Our Strobe Glasses are very compact, weighing less than 55g. They feature a fully integrated shape, rendering them not only portable but made to fit on your face. The cost-performance ratio is far superior to the old stroboscope devices. Their usage is not restricted to a dark room and has been designed specifically for use in the field. .

When you see a high speed ball through our strobe glasses, which are appropriately set, you will see a series of multiple still images of the ball. Training your eye-brain coordination by looking at the sliced images, the brain will learn to predict the path of the ball. You can adjust the setting conditions according to the ball speed or the purpose of your training. This training will enhance your dynamic vision enabling you to eventually you are see a ball more clearly without their use. Improve your dynamic vision and take a giant step closer to peak performance!
