[{"data":1,"prerenderedAt":-1},["ShallowReactive",2],{"content-seo:dynamicVisualAcuity":3},{"description":4,"seo":5,"faq":8},"Dynamic visual acuity is the ability to make out detail on something that is moving — the skill a batter uses to read a pitch. This free game turns it into a quick challenge: a number slides across a box from left to right, and once it has passed you type what you saw on the on-screen keypad.\n\nAt level 1 the number takes about 2.1 seconds to cross the box; every level after that is 0.15 seconds faster, down to a floor of 0.38 seconds from level 13. Levels 1–3 use two-digit numbers and three-digit numbers start at level 4. A correct answer adds the level number to your score and moves you up; a wrong answer costs one of three lives and you replay the same level with a new number.\n\nYour grade comes from the highest level you clear: Hawk Eye at 12 or more, Sharp at 9, Solid at 6, Warming Up at 3 and Rookie below that. Scores go on a ranking, and you can send your result to a friend as a challenge link. It is a game, not an eye exam — screen size and viewing distance change the result, and it does not measure your eyesight.",{"ogTitle":6,"ogDescription":7},"Dynamic Visual Acuity Test | Read the moving number - Giggleus","👀 A number streaks across the box — read it before it's gone.

The grade depends on the highest level cleared: 12+ Hawk Eye, 9+ Sharp, 6+ Solid, 3+ Warming Up, otherwise Rookie.",{"question":16,"answer":17},"Is this an eye test?","No. It is a game for fun and does not measure or diagnose eyesight; screen size, brightness and viewing distance all affect the result. If you notice changes in your vision, see an optometrist or eye doctor."]
