Brien Holden Institute: Prevalence: 50% of the world myopic by 2050
American Academy of Ophthalmology: Myopia is a significant, prevalent disease in children with increasing rates of progression.
Is Myopia a Disease?
Jeffrey J. Walline, OD PhD, Associate Dean for Research, College of Optometry, Columbus
Oxford Dictionary definition of a ‘disease’ is:
a disorder of structure or function in a human, animal, or plant, especially one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury.
– Myopia is a mismatch between the optics and length of the eye, so it is a disorder of structure
– Myopia occurs in humans
– Myopia produces distance blur (symptom)
– We didn’t fall down and suddenly become myopic, so it isn’t the direct result of physical injury
Myopia precisely matches the definition of a disease, but for some reason, optometrists don’t tend to think of it as a disease. If optometrists don’t think of it as a disease, then why would we expect our patients or insurance companies to do so?
Because myopia is a disease, we need to do more than simply treat the symptoms. We need to disrupt the disease progression in order to truly treat the disease. Would you ever prescribe only visual field-expanding prism to treat glaucoma? Of course not, so why would you treat progressing myopia with single vision lenses only?

The more myopia your child has, the greater their risks of eye disease later in life.

If you act early, myopia can be slowed, giving them better sight and less risk of eye disease later in life.
