For clarification, the lines are caused by the mirrors’ edges, and the cross hatch pattern common on street lamps in pictures comes from a filter (or scratched lenses/other filters.)

With your normal eyeballs, it comes from defects like cataracts.

You don't need defects in your eyes to see it. All you need to do is to close your eyes slightly and look through your eyelashes. The light refracts on the lashes and creates a star-like pattern.
