How do you solve the most obvious problems of focus? Is there a really strong lens on the front of this thing?

I keep thinking of this problem when I hear about things like heads-up contact lenses and so on. It is a tremendous eyestrain for me to focus on anything within a meter, and so I'm often relaxing my eyes by looking away from my laptop at distant things. Within 10-20 cm or so it is extremely difficult to focus on anything; within 10cm it is actively impossible.

So are they really using a lens that can make a 1cm-away display look like it's 100cm away?
