Similarly, if you've had LASIK and struggle with halos and starbursts around taillights and headlights, try increasing the brightness of your instrument panel. It will cause your irises to close in response to the brighter light, which allows less light in through the uncorrected area of your corneas. Basically: in LASIK surgery they only apply correction to the very center area of your cornea, and the more your irises open, the more of those higher order aberrations you will see.
