They are the inseparable best friends who share everything, including a love of sport, and now together they are enjoying the freedom of not having to wear spectacles, thanks to revolutionary new contact lenses.
Ahead of National Eye Health Week this week, 12-year-olds Abbey Pollock and Alex Kelly have had their lives transformed in the past few months by the new nocturnal lenses which have allowed the girls to put their glasses away for good.
The new Ortho K lenses are worn at night when the children are sleeping and work to temporarily correct their vision so that they don't need to wear their glasses the following day.
The Methody first formers, who live in Carryduff and also share a love of the band One Direction, are only now aware of just how challenging playing sport had been when they depended on their glasses.
Both girls play hockey for Belfast Harlequins. Alex is also a judo champion with a host of top UK and Ireland awards, while Abbey is a keen gymnast.
Even though both have excelled in their sports, they now are thrilled to be playing with the added advantage of being able to see clearly for the first time – not just the hockey ball, but for Alex her judo opponent, while for Abbey the gymnastic bar is in much sharper focus. The girls love the fact that they no longer have to worry about forgetting their glasses when they leave home.
Their lenses were fitted at Gillian Gervais Opticians in Carryduff. Gillian was one of the first opticians to bring the new lenses to the province and is still only one of a handful of companies to offer them.
It's only in the past year that the full benefits of the lenses have been realised and only now that word of their express life changing advantages is starting to spread.
Nocturnal lenses are unique contact lenses that take away your short sight while you sleep. They do this by gently changing the shape of your eye in a controlled way.
All contact lenses change your eye in this way but nocturnal lenses are made to suit your eye precisely and enhance the effect to correct your vision.
