◎ Recover eyesight by training eye eyesight and intracerebral eyesight

Visual acuity includes eye visual acuity and intracerebral visual acuity. Eye visual acuity is what is commonly referred to as visual acuity, which is the ability of the eyes to focus on what they see.
Intracerebral visual acuity is the ability of the brain to recognize and visualize what it sees.
Ideally, not only eye vision but also intracerebral vision should be trained to restore vision.
Use this app to train your eye and intracerebral vision with 3D stereoscopic training.

◎ Three 3D stereoscopic training
■ 3D Gabor patch
It is a training performed using an image called Gabor transform. Blurred 3D Gabor-transformed images are thought to easily act on the visual cortex of the brain, and their application is used for vision recovery training.
■ 3D stereogram
It is a training to see the image by the parallel method and the cross method of 3D stereogram. By consciously looking at the 3D image while focusing on it, you will train your eyesight in the brain, and the work will train the muscles of the eyes that you do not normally use. It can also be a stretch of.

■ 3D number touch
It is a training to train the ciliary muscles by randomly following images with different sizes, shapes, colors, and numbers. When a person sees things with his eyes, the ciliary muscle, which is the muscle of the eye, adjusts the distance to the object and the angle of refraction of light, and the ciliary muscle is trained by number touch training.

◎ Visual acuity measurement
The app also comes with a vision measurement tool. You can continue the above 3D stereoscopic training every day and check your eyesight condition with the eyesight measurement tool on a regular basis.

◎ Summary
Three 3D stereoscopic trainings to train eye movements, muscle movements, and intracerebral visual acuity. This app allows you to enjoy 3D stereoscopic training as if you were playing a game, so you can continue it every day.

### 2/5 — 何とかしてほしい

*2022-04-12*

有料版に変えた途端に固まる・・

### 1/5 — 誤動作、誤反応が多い。

画面タッチに反応しなくなったり、突然画面が変わったりする。其の頻度も段々と上がって来てるように感じる。

### 4/5 — やっぱり使いやすい

*2020-09-14*

無料版から使っていましたがこちらの方が動作が軽く、より使いやすいと感じました
制限時間の通知もアラームだけではなく時間も表示と1日のトレーニング回数も表示もあったらより幸いです

### 4/5 — 楽しみながらできる

*2020-09-05*

ゲーム感覚でできて良いです。広告無しの方が動作も軽くなりました。続けたいので、ステレオグラムなど種類を増やしてもらえると嬉しいです。
また、平行法をやるときに、タブレットでは画像が大きいため難しいです。小さめの画像があるといいのですが。

### 5/5 — ガボールパッチがとても良い

*2020-04-05*

書籍と比べて直接触って消すので凝視してかなり効きます
ステージセレクトや大きさ設定があると嬉しい
ガボールパッチの二角取り等もありかもです

*2020-02-15*

ステレオグラムの画像で途切れるところがあります。

重要なとこなので修正してほしい。

**Developer response:** >ステレオグラムの画像で途切れるところがあります。

画面が暗くなる症状は解消しました。

### 3/5 — ステレオグラム以外は最高です

*2020-02-08*

ステレオグラムの平行法のときに
黒い点に集中したいのに
黒い点の上に、「平行法」や「閉じる」などの文字があるため、
他のアプリではうまくできてもこのアプリではできない
できれば、文字を上側ではなく、下側にしてほしい

**Developer response:** >文字を上側ではなく、下側にしてほしい
了解しました。無料アプリの場合下にバナーがありできないですが
こちらのアプリは有料版のためバナーがないので可能です。
次回のアップデートの時修正しますのでしばしお待ちください。

バージョンアップして改修しました。
