Special contact lenses have given a young boy back his dreams of becoming a nuclear physicist.
Kristian Allan Cook said that when he started wearing scleral contact lenses, "my whole world lit up".
The youngster was diagnosed with keratoconus, a condition which distorts the shape of the cornea and affects sight, in his right eye when he was just ten.
Unable to wear ordinary contact lenses, the Bangor-based boy lost his social life as he could not see his friends" faces and was advised to stop playing sports.
But his mother Sarah did some extra research and took Kristian to the famous Moorfields Eye Hospital in London, where he was prescribed scleral contact lenses.
Kristian describes the day he tried them as "the best day of my life" and recalled how his father had wept with joy at his son"s sight being restored.
