Shades, rastro near Xavia.  They came with instructions from a German hippie doctor that if you put them on and stare at the sun, all will be chill.  I felt like I was in a prison.  Someone else said they felt like a fly.  I once went around Edinburgh for a few days wearing those decorating shades, or partially sighted big old boom shanking cover ups, with paint splattered all over them.  Loved the visions going on then.
