Know The Glow ®

Imagine losing the ability to watch a kite soar, see a fireworks’ display or count the stars. Sadly, many children don’t have to imagine it—they live it.

Nearly one in 80 children is at risk of blindness. Yet in most cases, it’s preventable and curable with a camera and with the knowledge of “The Glow.”

“The Glow,” an abnormal red eye reflex, appears as a white or gold pupil in photographs. Its reflective shine is an indicator of several potentially devastating and preventable childhood eye diseases.

Now YOU know … “The Glow.” Together we can envision a brighter future for our children by sharing stories, photos and a commitment to increase awareness worldwide.
