Footage of the incredible moment a little girl was able to see clearly for the first time has gone viral online, having attracted more than 5.5 million views.
The footage, which was shared to TikTok by Elderberrysultan, shows a little blonde toddler, who is wearing a pale pink winter coat and jeans, standing in living room.
A woman then leans in and places a pair of pink glasses on the child, who is legally blind, and the small girl becomes overwhelmed with delight as she runs about the room, excitedly looking at things and spinning in circles.
Text overlaying the footage explains: "Best moment ever. Riley was legally blind.
"We noticed around 2 years old that she called everyone 'mom' and 'dad' because she couldn't recognize faces. So we were able to get her glasses around Christmas time."
We can hear a woman saying "I'm going to cry," and asking Riley what she thinks.
The little girl then shrieks with joy and the woman says: "Come give your mom a hug. You can see my face for the first time."
The heartwarming video, which can be watched here, ends with the two embracing.
Elderberrysultan has captioned the clip, writing: "2 years ago today! #fyp #family #toddlersoftiktok #love."
