How it helps
Red-blue split views, eyes working together
Red-blue training glasses split the picture between the two eyes. Each eye sees its own part, both are needed, and the games only go well when they cooperate.
Nearly 20 training games
Anti-suppression, fusion and stereopsis practice turned into games -- children keep at it because they want to play.
Personalised training plan
Pick a training template that fits you and get a 60-session schedule: twice a day, about 15 minutes each.
Progress you can see
Every session scores itself; accuracy and difficulty are drawn as curves, so progress is obvious at a glance.
Calibrate before training
The picture difference and starting difficulty are calibrated to the two eyes' actual condition, and intensity adjusts automatically with performance.
Train right in the browser
Works on computers and tablets with nothing to install; the interface is available in Chinese and English.
Understanding binocular vision training
What is binocular vision?
Our two eyes each see a slightly different picture, and the brain merges them into one image with depth. The better the two eyes cooperate, the easier seeing feels and the more accurate distance and depth judgement become. Like muscles, that cooperation improves with regular practice.
How red-blue dichoptic training works
With red-blue training glasses on, the red parts of the screen are visible to one eye only and the cyan parts to the other. The games split the key targets between the two eyes so neither can sit out, then ask them to combine what they see into one complete picture -- practising anti-suppression, fusion and stereopsis step by step. This approach is known as dichoptic training.
Why train at home
Vision training works through daily repetition. Turned into games at home -- twice a day, about 15 minutes -- it is something children actually want to keep doing; the plan schedules itself, and accuracy and difficulty are drawn as a progress curve where every bit of change shows.
Who it is for
- Children and adults who want to exercise eye teaming and depth perception
- Families keeping up daily vision training at home
- Restless kids -- game-based training is easier to stick with
- Anyone who wants to see their change on a progress curve
Vision Training is a home vision-training tool, not a medical device, and provides no medical advice. If you have an eye condition or discomfort, consult a professional doctor.

FAQ
What do I need?
A computer or tablet, plus a pair of red-blue training glasses. They are easy to buy online, and it does not matter whether the red lens sits on the left or the right — you can adjust that in Settings.
What are red-blue glasses?
A pair of glasses with different-coloured lenses, one red and one cyan. Each eye can only see the matching colour on screen -- the basis of dichoptic split-view training.
How long is a day's training?
The default plan is twice a day, about 15 minutes each. Consistency matters more than duration.
What ages is it suitable for?
Any child who can understand and play a simple game can use it; younger children should be accompanied by a parent. Adults can train too.
Can adults train too?
Yes. The difficulty adjusts to performance automatically, so adults and children both find the right intensity.
Is the training tiring?
It is playing on-screen games at an adjustable intensity. Take a break whenever you feel tired or uncomfortable -- never push through.
Does progress carry over to a new device?
Yes. Records and plans are stored with the account; sign in on another computer or tablet and continue.
How soon will I see changes?
It varies from person to person. Vision training is gradual; what matters is daily consistency -- watch your own change on the progress curve.
