Know The Glow ®


Know the Glow is a global nonprofit leader in identifying preventable glow-related childhood eye diseases.

We empower parents to see their child’s vision in a new light by raising awareness about The Glow (medically known as leukocoria) and encouraging them to make sure their young children receive comprehensive eye exams by an eye specialist.

When caught early, more than 80% of all childhood blindness is preventable
