Yeah, Lego is a little complicated these days. Still good fun though.
I have a few different sets. I use a pair of those multifocal ones for work as I can look up and see relatively normally and when I know I'll be at the the computer or reading mostly I use single focus ones.
For shooting I use my Oakleys with multifocal lenses in them, these are the ones you'll see me wearing in images on hive. The were stupidly expensive but give me the front sight-focus for hand guns and I can see the reticle perfectly on my long guns...Bloody hell, when did it all get so complicated?!
Oh I know, when I got older.
