Baby lights up with joy after seeing her mom for the first time

For many people, getting glasses can vastly change the way you see the world.

For four-month-old Tilly, glasses allowed her to see clearly for the first time -- and the first thing she laid eyes on was her mother.

In potentially the most heartwarming video ever made, footage shows Tilly putting on glasses and completely lighting up when she sees the woman who has been caring for her.

It warms her parents' hearts too -- love and joy fill the room.

Tilly's father caught the adorable sight on camera, according to Daily Mail.

Her tiny pink specs come complete with an elastic head trap.

"I think she likes them," her dad says in the video.

The video was filmed in December 2015, but has only recently gone viral.
