A woman was diagnosed with a rare brain condition after going for a routine eye test - as the optician spotted something unusual during the examination.
Emelia Jones, 20, suffered from headaches for months and they were growing in intensity, sometimes leaving her bedbound in agonising pain.
The NHS call handler, from Rhondda, Wales, thought maybe she needed glasses so went to her local Specsavers' optometrist to get her sight checked.
