      Hi Harty
      The usual reasons for people being short-sighted and/or needing glasses are to do with the ‘length’ of the eye, and the size, shape and position of the lens. I know we all think of the eye as being a sphere, but it is in fact slightly elongated, and can become more so as well get older. In some people, perhaps like you, this can happen when you’re still young, and it can continue to change. I expect you get regular eye checks, so the optician will be able to adjust your glasses/contact lenses as you grow.
