The documentary "Blink" follows a family in Montreal as their children's vision gradually disappears

"Blink," a new National Geographic documentary, tells the touching story of a Montreal family where three out of four children have been diagnosed with retinitis pigmentosa, a condition that gradually leads to vision loss.

Faced with this life-changing news, parents Edith Lemay and Sébastien Pelletier took their family on a world tour to experience its beauty while their children still can.

Sébastien Pelletier shared how the overwhelming positive response from people inspired them, with many drawing strength from the family's story.

"We chose to travel the world, but everybody can do it in their own way," said Pelletier, emphasizing the importance of finding positivity in difficult situations.

Lemay also reflected on the impact of their journey. “So many people tell me, after the pandemic, they needed something beautiful, and they thanked us for sharing our story.”

She added that while they initially set out to see the world, the connections they made with people along the way became the most meaningful part of the experience.

The film, directed by Edmund Stenson, explores themes of resilience and confronting the unknown. Stenson was particularly moved by how emotionally open Edith and Sébastien were about their uncertain future.

He collaborated with Montreal-based production team Eye Steel Film, director of photography Sébastien Francoeur, and editor Ryan Mullins to create the documentary, aiming to authentically capture the family's journey.

Lemay, who managed the family's logistics during the trip, later published a book titled Plein Leurs Yeux about their adventures. "Writing a book was the last thing I thought I’d do," she said, but she is glad to have shared her story in her own words, as a gift to her children.

"Blink" is set to premiere in theaters on October 4.
