Push the limits of eyesight!
This is a game that challenges your eyesight.
*This app does not allow you to perform the correct test.

- Game Introduction
This is an unexpectedly simple game that lets you compete for eyesight on your smartphone.
You can measure your eyesight from 0.01 to 2.0 or higher.
Measurement results are recorded each time.
With the ranking function, you can compete with your friends and other players nationwide.
Can't test your eyesight accurately, but we've made adjustments to make it fun to play.
You may get a slightly better result than usual.

*As physical devices, they inevitably have their limitations. At the top of the ranking, we may have to use our “senses” instead of our "sight".


- How to play
Use the up, down, left and right buttons to answer the questions within the time limit.
If you get it wrong three times, the game ends.
The faster you answer, the more time bonus you get.
The total score of eyesight and time bonus will be reflected in the ranking.


-Record
Your most recent score and your best score to date will be recorded in the game.
If you are connected to the network, your score will be automatically reflected in the national ranking.


-Other
If you make a mistake, you will be notified with a vibrator
(you can also turn it off from the settings).
