Myopia, or nearsightedness, is a condition where the light entering the eye focuses in front of the retina, rather than on the retina, creating a blurred image for far away objects. Objects up close are often seen clearly, so this is how this condition got its name.
The eye on the left is a normal eye. The eye on the right has myopia, notice the light focusing in front of the retina. Photo taken May 5, 2023 from:

Nearsightedness is becoming much more common now than it was several years ago, and the problem has only been exacerbated by the COVID-19 pandemic. According to CooperVision, in a study of Canadian school children aged 11-13, 30% were nearsighted.
There are multiple risk factors including family members with nearsightedness, time spent outdoors and the amount of time we are spending on the computer and tablets, often at close working distances.
So every time you or your child goes to the optometrist, the prescription increases and stronger glasses are needed to see clearly. Why is this important? Your child can simply get a new eyeglass or contact lens prescription and they will be able to see well again right?? WRONG!! Nearsightedness does not come without complications!!!
We want to make every effort to keep the length of the eye below 26mm. Myopic individuals with an axial length less than 26mm have a lifetime risk of vision loss of 3.8% (best corrected vision of 20/40 or worse by age 75)1. If the eyeball then grows larger than 26mm, this risk jumps to 25%. That statistic has really driven home for me, the importance of treating young myopes as early as possible so that the growth of the eye can be slowed enough to allow the eye to continue growing at a normal rate throughout the rest of childhood and through adolescence.
There are multiple risk factors for the onset of myopia as well as myopia progression:
Having myopia puts you or your child at an increased risk for eye disease later in life. In some cases, eye disease caused from myopia can cause blindness. These include:
As our eyes continue to become more nearsighted, the eyeball continues to grow larger and larger. The problem with this is that as the eye grows, the retina (the thin layer of tissue that contains the photoreceptors (seeing cells)) gets stretched thinner and thinner to cover a larger eyeball. This can cause an increased risk of vision problems in the future, some with the potential to cause blindness.
According to the information on MyopiaProfile.com, a -1.00 to -3.00 myope has 3X the risk of having a retinal detachment at some point in their lifetime. This risk increases to 9X if you get in the range of -5.00 to -7.00 and as high as 44X more likely if over -7.00!!!!!
This is VERY alarming! But the GOOD NEWS is, there is something you can do to slow down or prevent this progression.
The Tideman study looked at 12,386 European children with the purpose of generating percentile groups comparing the axial length of children, and their risk of nearsightedness in adulthood. In this study cohort, 87% or more of those found to have axial lengths in the 90th percentile or higher, were nearsighted. In the same group, 8% or more became highly nearsighted (greater than -6.00D of myopia) by adulthood. Those in the 98th percentile or higher, were very likely to end up with an axial length greater than 26 mm.
A similar study was done for a Chinese database of 12, 554 children by the San Diez group.
