Both mean a "brief look".
glance - usually done with more purpose
glimpse - This does not sound too good. I think "glimpse" sounds like there was less purpose or meaning in how something was looked at.
Both mean "to look at for a very short time" briefly - usually no more than a few seconds. Glimpse sounds a bit negative to me. Glance sounds a bit more positive.
