Challenge your visual acuity and reflexes with 超視力チャレンジ ゴールドエクストリーム. This game allows you to compete in tests of vision and reflexes on your iPhone, offering measurements from 0.01 to over 2.0 in visual acuity. Results are recorded for each attempt, and you can compete with friends and players nationwide through the ranking feature. While not a precise vision test, it provides an enjoyable experience with potential for slightly better results. Engage with a charming voice guide as you play.

Put your visual and reflex skills to the test by responding to prompts using directional buttons within a time limit. Three incorrect answers end the game, but quicker responses earn time bonuses, contributing to your final score.
