I'm going for a real/actual change of the root cause of the problem: the stock projector.
Amplification of the stock projector may seem like cheap easy idea- but - it simply does not fix the Fresnel style lens - that lens - bleeds light vertically = glare into oncoming drivers.
The cheap/best alternative is to remove the glass and replace with the STi-R glass - $60

A PROPER LED lens: $400:

You also have this as an option if you want to stick to HID:
$175 -

Here is a plug n play bracket for the 370z:

Others whom have already made updates can chime in with shield/washer modifications....
Secondary to this: The stock headlight cover/lens - this must be polished and polished the CORRECT way.
Here is the BEST guy on youtube that will demonstrate how to do this:
