Myopia and high degree myopia

Myopia, often known as "being short sighted", causes your vision to be blurry in the distance but clearer when looking at things up close. It is a very common condition of the eyes. For most people it can easily be dealt with using contact lenses or glasses, which will make your vision clear and crisp.

Development of myopia

You can develop myopia at any age, however it does have a tendency to develop in childhood or teenage years and it can get worse as you get older. Myopia in young children can get worse as they get older. Myopia can become more stable in adulthood; however there may be episodes where the myopia continues to increase. These episodes can happen at any age and are more common if you have higher levels of myopia. In general the younger you are that myopia begins to develop, the higher the level of myopia you will reach. For some people their myopia reaches a certain level and stays the same for many years.

It has become an issue of monumental importance affecting over a billion people around the world and it is getting worse.
