It was the moment when "cuteness went through the roof".

For the four months of his very short life, Leopold Wilbur Reppond, known as Leo, had been unable to see properly because of a rare disorder called oculocutaneous albinism.

As well as affecting the colour of a person's hair, skin and eyes, the condition also affects sight, meaning Leo would "see with his hands", touching things like his father's beard.

That all changed when his parents, David and Erin, got Leo a pair of glasses and put them on as family and friends looked on.

"Hi honey," Mrs Reppond greets Leo, who looks his mother in the eyes for the first time and smiles.

The moment didn't leave "a dry eye in the house", according to Mr Leopold.

"I had some issues holding the camera because I was crying so much," he told MailOnline. "I was overwhelmed with emotion. It’s just very touching. You cannot anticipate how you’re going to feel when something like that happens. It was very heartwarming. Leo looked at my wife for the first time and saw her for the first time."

The Repponds, who live in Seattle, Washington, had sought help from Los Angeles-based pediatric ophthalmologist Kenneth Wright, the newspaper said. The special infant glasses have normal lenses but the frames, made from a rubbery material, have no screws, no hinges and no sharp edges.
