Modelling a simple Helmet

Hi, i’m quite new to blender and these days i’m trying to “build” a robot, and i’m quite satisfied with that.
But …today i’ve encountered a problem with the helmet :slight_smile:
I want to create something like this (
but with two lens instead of one.
How can i make the holes in the helmet to place the lens?
How can i model the lens?
Some advice for modelling the helmet? Curves? Surfaces?
