Myopia (short-sightedness) occurs when rays of light are brought to a focus in front of the retina because the optical power of the eye is too great, or the eye is too long. The latest research finally proves that contact lenses can slow down the progression of Myopia and, in some cases, halt it all together.
Between the ages of seven and 11 years, six percent of the population has 0.5 dioptres (the unit used to measure short-sightedness) or more of myopia.
The big jump in myopia comes between ages 12 and 13 with an increase of 25 percent in young people who have a 0.5 dioptres. We think that at this age the increased over-growth of the axial length of the eye during the puberty growth spurt.
