- very intense sun here but I only have minimal level for vision safety and don't think it helps much.

You said it. If you have a minimal level of tinting, it's really not helpful.
When you mentioned your "dealer" (I am assuming car dealer) they will typically not have anything that is too dark. Too much legal exposure, at least here in Florida.
Here, there are hundreds of local tint shops all over the place (I got my car done via a Groupon discount). They give you whatever you want.
