I just heard this story on a shiur and I freaked out, and wanted to tell you about it.
A few years ago, a bus on a lag baomer trip crashed and 3 young boys and a bus driver died. One of the boys who died, who had been a chavrusa with a boy who survived, came to his friend in a dream and explained what had happened to them after they died; how they got to shamayim, how they were judged, and so on. The boy said that one of the boys in their group was exceedingly careful with shmiras anayim; he took it upon himself to never look at anything inappropriate or untzniyut. When he died, the boy in the dream said, "THIS BOY WAS ACCOMPANIED STRAIGHT TO THE KISEI HAKAVOD". He was the only one of the people that died that went straight to HASHEM, and all in the merit of guarding his eyes!
