While digging through my various objects, I found something interesting in my health booklet:
Goh Yu Xuan Primary 2: Right Eye 6/24 Left Eye 6/24 (in short one quarter the vision of normal eyes) Primary 3: Right Eye 6/36 Left Eye 6/24 Primary 4: Right Eye 6/24 Left Eye 6/24 Primary 5: Right Eye 6/18 Left Eye 6/36 Primary 6: Right Eye 6/18 Left Eye 6/36 Secondary 2: Right Eye 6/18 Left Eye 6/24 Secondary 4: Right Eye 6/12 Left Eye 6/12
Win. My vision basically improved the more I performed tasks ordinarily detrimental to one's visual acuity. Perhaps it is a sign.
