Duchess Sophie reminded fans of her duaghter Lady Louise Windsor's triump as she embarked on an important royal visit on Mondaty, November 10.
The Duchess of Edinburgh, 60, will vist to the Divino Niño vision centre in Peru, where she will learn about the centre's work in treating glaucoma, pterygium and other eye conditions, a cause close to her heart due to Lady Louise's own experience with esotropia, a rare eye condition.
Louise has set an example by overcaming the health battle to shine again. She's achiving excellence in her studies and encouraging her royal cousins with her spirits to cope with the crisis.
Prince Edward's daughter and King Charles III's niece, Louise, was born with esotropia and underwent surgery at 18 months old.
Loiuse, now 22, had to undergo another procedure in 2014, which corrected her vision.
According to medical experts, Esotropia is a form of strabismus where one or both eyes turn inward toward the nose, causing them to be misaligned.
The condition may also affect vision and coordination, and common treatments include glasses, surgery, or botulinum toxin injections.
Sophie, who's the Global Ambassador for the International Agency for the Prevention of Blindness (IAPB), received the honour following her personal experience with it.
She's visiting South America at the request of the Foreign, Commonwealth and Development Office. She is expected to visit Peru, Panama and Guatemala. She will also visit Belize, as part of the royal family's engagement with the Realms.
