Harvey Webb lives life in black and white

A toddler from Tonbridge in Kent who has a rare sight defect is involved in a campaign to raise awareness of the condition.

Harvey Webb's condition, Achromatopsia, means that the brighter the light, the harder it is for him to see. He can only see in black in white and has to wear dark glasses.

The condition is incurable but both Harvey and his younger sister Megan are involved in research for treatment with Moorfields Eye Hospital in east London.

The family is also helping to raise money to expand Dorton House nursery, near Sevenoaks, which caters for blind and partially sighted children.
