i have fairly poor night vision normally, and my long-distance focus is pretty bad too (probably near 20/40 or 20/60 in my right eye) so i might need corrective lenses eventually, but i don't wear any glasses or contacts now or when i trip.
while sober, i LOVE the lensing effects I sometimes get around bright points of light. it is most noticeable during the night when my pupils are dilated, streetlights and other bright points will have various halos around them that will phase in and out as my pupils adjust microsopically. it's quite beautiful how such tiny autonomous movements inside the eye will create such large interference effects that fill the center ~15% of my visual field.
even during the day, if i unfocus my eyes (like you're looking for floaters) and stare with a bruight point somewhere in my central visual field, i can see "mesh gratings" of interference patterns across the bright area that I can only attribute to subtle lensing effects inside my eye. i'm sure each person's eyeball is different, and each retina has a different set of strengths/weaknesses in terms of focus and color sensation.
