The lady, in her 20s, was sitting in the back of the cab in a slow-moving traffic jam in Bangkok, Thailand, and applying eyeliner on the way to see her friends when the accident happened.
The cab driver crashed into a pick-up truck in front – jolting the woman forward. She hit the seat in front, accidentally thrusting the pencil into her left eye.
Incredibly, the stick missed the vital parts of her eye and her sight will be unaffected, according to medics who treated her.
Paramedic Thanabodee Sabbodi said while the crash was minor the 'freak accident' had caused half of the pencil to plunge into the eye socket of the young woman, who has not been identified.
He said: 'The crash happened at 5.20pm in Din Daeng area of Bangkok while the lady was putting on make-up on her way out for the evening.
'We received a call and there was one injured female with an eyebrow pencil inserted into her left eye.
'She was in a lot of pain when we came but she could still talk to us and explain what happened. There was not a lot of blood but she had a small nose bleed.'
The girl was still conscious and taken to the Rajavithi Hospital where medics removed the pencil without any lasting injuries.
Thanabodee added: 'The rescue team and the doctors did a great job to help the victim.
'This should be a warning to women who do their make-up while cars are still running because accidents can always happen.
'This was a strange accident and unexpected but nobody can predict these incidents. We have to be prepared."
