A video of a young baby trying her glasses for the first time has gone viral, with more than 25 million views on Facebook.
The video, posted by Jessica Sinclair, shows the reaction of her 10-month-old daughter Piper smiling after being able to see her parents with her new glasses.
Piper was prescribed her glasses following an eye examination by Dr Josiah Young, an optometrist based at Opticare Vision Centers in the US.
Dr Young said: “This is why I love to come to work every day. I can’t express how much joy it brings me to see this video.”
