According to this abstract, minus lenses caused mild decrease in halos
by constricting the pupils. I'm asuming if it works for halos it might
work for starbursts.  So what are minus lenses?  Anyone had experience
with them?

PURPOSE: To evaluate the amount of miosis induced by over-minused
lenses and to assess subjective reduction of halos following laser in
situ keratomileusis (LASIK) with such lenses. METHODS: Part I: Infrared
pupil diameter was assessed in 14 patients who had not had ocular
surgery. The accommodative/miotic reflex was stimulated with concave
trial lenses in -1.00-D increments up to -4.00 D while viewing the
20/40 acuity line. Part II. Subjective halos around a distant light
were assessed in 14 patients following LASIK for myopia, with and
without a -1.00-D lens over manifest refraction. RESULTS: Part I: 100%,
79%, and 64% of patients clearly saw the 20/40 line with a -1.00-D
lens, -2.00-D lens, and -3.00/-4.00-D lens, respectively. Mean pupil
diameter decreased by 0.2 mm with the -1.00-D lens (P = .02), 0.5 mm
with the -2.00-D lens (P = .003), 0.9 mm with the -3.00-D lens (P =
.008,), and 1.1 mm with the -4.00-D lens (P = .008). Part II: 11 of 14
patients (79%) noticed a decrease in the size of the halo (30% average
reduction) when over-minused by -1.00 D. CONCLUSIONS: Pupil diameters
and halos decreased with a -1.00-D overcorrection in patients following
LASIK. Patients with pupil-dependent night halos after LASIK may
benefit from mildly over-minused lenses.
