Leber Hereditary Optic Neuropathy causes sudden, severe, painless loss of central vision, usually first in one eye, then within a few months in the other. 

Adjusting to LHON

Losing central vision is scary. Figuring out what to do when it happens is confusing, and there are many issues to address all at once.  


This site was created by a family affected by LHON. By sharing what we learned as we struggled to cope with LHON, and what we've learned over the years since it first happened, we hope to help make the adjustment process smoother for others.
