I'm very nearsighted. There are a few things I sometimes enjoy looking at without my glasses on, and fireworks are among them.
I wish I could photograph, or video, what I see, for those of you with good vision. I don't know what special lens or contorted photoshop manipulation could make a picture of it; I don't think I've ever seen one. Out of focus, but not in a way that makes it blurry, exactly. It's more like the lens reflections you sometimes see when the sun or streetlights are in a photograph, but these more discrete, compact points of light make smaller, tighter patterns, with bits of moiré.
You see a sudden pinpoint bright flash, then a slowly exanding sphere of dimmer little lights starting from that point; I see a sudden circular/hexagonal pattern of light so large it takes whole seconds before the sphere expands to fill up the area taken up by its afterimage.
You see sparkly weeping willow glitter patterns slowly falling; for me they set smooth gradient background colors for the sky. Bright points of red and blue and white shooting around evoke old Atari 800 video games and Commodore 64 sprite graphics. Bright lights shooting slowly upward to detonate, are semicircular flying saucers taking off. Standard fireworks, where many lights of the same size and color form the surface of a sphere, appear to me as giant richly-connected multicolored glowing volvox colonies. And when lights from neighboring fireworks lost their thrust and start falling together, red & blue alternating, I get overlapping patterns, venn diagrams of red and blue and violet.
