vision jumps (big to small) and "colored sand"
My son is almost 12 and when he was about 4 he asked why bright reflections looked like "colored sand". He still has this phenomomon. The past year he now also has an occurrance where it is like a lens magnification switch being flipped, where everything appears smaller, then snaps back after a few seconds, perhaps several times. Anything familiar sounding that I can research? Costco took super high-rez images of his eyes and besides having my nearsightedness, his eyes are healthy.
