[Niigata University of Health and Welfare] Improving eyesight through games? A game-based therapy that helps children engage in amblyopia treatment 'fun-fully'
A research group including Niigata University of Health and Welfare has demonstrated that game-based training using the specialized 'Occlu Tab' tablet improves vision in children with binocular amblyopia. Published on May 19, 2026, in the international journal 'Clinical Ophthalmology,' this study presents a new option for making therapy enjoyable, addressing the challenges of traditional, difficult-to-sustain amblyopia treatments.

A research group involving the Department of Vision Science at Niigata University of Health and Welfare (NSG Group), including lead author Mr. Tatara, Dr. Zaynutdinov of NAZAR Eye Center (Uzbekistan), Dr. Ishigaki of the University of Electro-Communications, and Dr. Handa of Kitasato University, has revealed that game-based training using the 'Occlu Tab' tablet improves vision in children with binocular amblyopia (a condition where vision in both eyes fails to develop adequately).
The paper was published in the international journal 'Clinical Ophthalmology' on May 19, 2026.
## About the Research
[Research Overview]
Is there an image that 'games are bad for the eyes'? It is true that prolonged near-distance focus can lead to myopia progression or eye strain. However, for an eye disease called 'amblyopia,' games can actually serve as therapy.
Amblyopia is a condition where visual function does not develop sufficiently, and treatment is only possible during a child's developmental growth period. The conventional treatment method involves patching the stronger eye to force the use of the weaker eye, but this often meets resistance from children, making treatment consistency a major challenge.
In this study, game-based training was conducted using a special tablet device called 'Occlu Tab' (the iOS version is known as 'Occlu Pad'). Occlu Tab is a tablet with a unique structure that allows the image to be seen only through specialized glasses.
With Occlu Tab, the tablet screen is visible only through the special glasses and remains invisible to the naked eye. Furthermore, because the eye not undergoing training cannot see the screen even through the glasses, the child naturally uses the eye intended for training while playing the game.
Occlu Tab settings allow the screen to be visible only through the weaker eye. Therefore, the child is incentivized to engage in the game, which in turn exercises the weaker eye. Previously, Occlu Tab was used for treating unilateral amblyopia. This study has clarified its therapeutic efficacy for binocular amblyopia by alternating training between the left and right eyes.
[Researcher Comment]
During amblyopia treatment visits, parents often say, 'I couldn't follow the training instructions this time' or 'We could only practice for a few minutes a day.' The greatest advantage of Occlu Tab is that it turns games into training, enabling children to participate happily and actively.
We were able to demonstrate through international collaborative research that a game-based training device developed in Japan can contribute to amblyopia treatment. I am pleased that Japanese technology can contribute to global medical care.

FAQ
Occlu Tabとはどのようなデバイスですか？
専用の眼鏡を通してのみ映像を見ることができる特殊な構造のタブレット端末です。肉眼では画面が見えない仕組みで、訓練対象の眼のみでゲームをプレイするように誘導できます。
弱視治療にゲームを用いるメリットは何ですか？
従来の眼帯を用いる治療に比べ、子どもが楽しく積極的に訓練に参加できるため、継続率の向上が期待できる点が最大のメリットです。
本研究の新しい知見は何ですか？
従来は片眼性弱視の治療に用いられていたOcclu Tabを使い、左右の眼を交互に訓練することで、両眼性弱視に対しても治療効果があることを明らかにしました。
この研究はいつ公表されましたか？
2026年5月19日付で、国際誌「Clinical Ophthalmology」に掲載されました。
どこで研究が行われましたか？
新潟医療福祉大学、ウズベキスタンのNAZAR Eye Center、電気通信大学、北里大学による国際共同研究として実施されました。
