There are different categories of aveiros, some are forgiven with teshuva alone, some need yesurim ch"v, etc. The worst aveiroh of Chilul Hashem is only forgiven with death, r"l.
However, this psak can be accomplished in a different manner. It says that 4 people are considered like a meis - a dead person - and one of them is someone who is blind. If a person, when faced with temptation in shmiras eynayim, closes his eyes - he makes himself like a blind man - with that he receives a kapparah for even the worst aveiroh of chilul Hashem.
