One of the rules is, that he has to make direct eye contact. Yet he's able to
geass about twenty people at the same time in Episode 1 from Season 2. He even
is able to do it later, too. So how can he do this?

How can Lelouch use his geass on so many people?


On the Code Geass Wikia it says

> Lelouch's Geass manifests itself as "the power of absolute obedience," which
> allows him to plant commands within a person's mind **upon direct eye
> contact**.

Geass](http://codegeass.wikia.com/wiki/Geass#Lelouch_vi_Britannia.27s_Geass)

while yes it does say it works upon direct eye contact it doesn't necessary
say that both parties need to make direct eye contact.

i believe that Lelouch's Geass works similar to [Superman's Heat
Vision](https://scifi.stackexchange.com/a/91074/20916)

with Lelouch's Geass it expands out and through obstructing this "widening
cone" with his Zero helmet he can focus it slightly to one person. from there
he should realistically be able to see his target's eyes even if his vision
isn't focused on them

My evidence showing Lelouch alone just need to be able to see his target's
eyes is in [Season 2: Turn 15 - C's
World](http://codegeass.wikia.com/wiki/The_Cs%27_World_\(episode\)) when
Lelouch goes to order Charles to kill himself by having the Shinkirō release
mirrors and using one mirror bounce his Geass around to target Charles without
Charles being able to target him which his Geass too needed eye contact.

this way the Geass expands outwards but the power is reflected to the next
mirror and continues reflecting until it reaches Charles as since Lelouch
could see Charles eyes in the mirrors then his Geass has to be able to reflect
back the opposite way as indicated by how [light is
reflected](http://www.physicsclassroom.com/class/light/Lesson-2/Light-
Absorption,-Reflection,-and-Transmission)1

this would also explain why the United Federation of Nations' counter measure
to his Geass was to trap him in an isolated room and display him on a monitor.

my evidence as to Lelouch not needing to focus on the target eyes is when his
Geass went out of control while talking to Euphie. it's just my personal
interpretation but i do not believe Lelouch was focusing on Euphie's eyes but
her face as he was more or less allowing Euphie to win and amend his plans to
fit with her own and he was joking about Euphie how he could order her to
"kill the Japanese", however he could realistically look into her eyes at any
point while looking at her face

While one can argue _"Lelouch's power went out of control then so he can no
longer focus it"_ lets remember that his geass was out of control in Season 2:
Turn 15 - C's World and when he first gained his power he ordered a group of
soldiers to kill themselves and i seem to remember there was times where he
would open up one part of his Zero Helmet to use his Geass

1: to put it simply, when you look at a red cube it isn't red it's absorbing
every other color of light except red which is being reflected back to our
eyes. so if Lelouch can see the purple on Charles's clothes in the mirrors
then that means the purple light being reflected from Charles's clothes to the
mirrors and then to Lelouch's eyes
