Sports Vision Training -
'The Trigger' to level up your performance

Perhaps you know that there are several vision skills, such as, Dynamic Vision, Eye Tracking, Peripheral Vision, Depth Perception, Eye and Hand Coordination, etc.

But you might not be aware of that better vision skills improve your performance dramatically.

At the same time, you might not know that vision skills can be improved by training just like muscle of your body.

All sports start with vision. Every reactions start with vision.
Just as athletes carry out physical training almost everyday to improve their reflexes and timing, sports vision training is another 'must'.

LCD Flash Lenses improve your eye vision skills

PRIMARY Strobe Glasses equipped with high speed LCD lenses make it more difficult to see or to collect visual information by intermittently flashing between transparent and opaque at a frequency set by the user.

This unusual vision stimulates and trains eye-ball muscles. As the result, as eye-balls get to move quicker and smoother, eye vision skills are improved. This resistance training forces your brain to become more efficient as well.

10-year children to aged people, amateurs to professionals, or lighter training to heavier training, PRIMARY Strobe Glasses are very easy to use and effective.
