[Star Wars] Can a jedi theoretically tap deeply into the dark side and have Sith eyes on their own?

Without being a Sith apprentice?

For example, a Jedi is placed in an enclosed chamber and he rages so much that he does enough to unleash the Dark Side of the force within him.  Can he self-transform his eyes into a Sith Lord's without being an actual Sith himself?

If I recalled correctly, Dooku never tapped fully into the dark side to have the same Sith eyes, but he was in every way an extremely powerful Sith Lord already.

They are not "Sith Eyes." You make it sound like they are exclusive to Sith Lords, which they aren't either. They are simply a sign of being deep in the Dark Side.

Dooku did get the yellow eyes, but usually only at certain points when using the Dark Side in *The Clone Wars* CGI series.
