Do get in to your surgeon. They should do a refraction (glasses test) on both eyes distance and near, corneal topography, macular OCT (rule out macular edema) and check the position of the IOL and the clarity of the posterior capsule. If the LE can be refracted to 20/20 then consideration should be given to getting glasses at least for night driving.
Sometimes it clears but at others it does not and is permanent: Start by reading this article:

There are lost of possible causes and I think it unlikely dry eyes. If so instilling a drop of artificial tears to your eye at night should make the LE see as good as the RE. Possible causes include a moderate or large residual refractive error, IOL malposition, opaque posterior capsule, excess corneal astigmatism, macula edema. You may have to wear glasses for driving at night. This problem is called dysphotopsia. It has been discussed many times on these eye forums.
