Depending on the mutation and pedigree, most female carriers do not lose vision but upt to half of males do.

Some mothers leber hereditary optic neuropathy a LHON gene mutation do not show symptoms, but family history often reveals female relatives with visual loss at an early age.

Mutations in mitochondrial DNA can only be inherited maternally because ova contain mitochondria, while sperm do not. All of the offspring of a mother with an mtDNA mutation will inherit the gene. A male with a mitochondrial DNA mutation cannot transmit the mutated gene to any of his children.
