Headlights, streetlights, and neon can look smeared, spiked, or soft at night because your pupil widens and more peripheral optics come into play. Uncorrected cylinder and sphere, dirty or scratched lenses, dry tears, and early lens clouding are frequent educational associations.
Categories and timing
Refractive, ocular surface, corneal, lens/media, and occasionally retinal/optic causes can contribute. Gradual night glare is an exam topic; sudden monocular night blur with flashes/floaters/curtain is urgent.
