Method: A collection of statements about myopia are provided with references to demonstrate that a section of the research or clinical community supports the statement. The topics under discussion are reviewed critically with reference to the literature. Results: The following statements are considered to lack sufficient supporting data to be considered as evidence-based: low-dose (0.01%) atropine slows myopia progression; relative peripheral hyperopia leads to myopia development and progression in children; undercorrection slows myopia progression; percentage treatment effect remains constant with continuing treatment; percentage treatment effect applies across the progression range; hand-held digital devices contribute to the myopia epidemic; more time outdoors slows myopia progression; the impact of outdoor activity on myopia incidence is due to daylight; subclassifications for myopia are effective; and myopia is a condition with a negative dioptric number. Conclusion: There are many hypotheses proposed to explain phenomena in the myopia field. Caution should be exercised in adopting conjecture until a robust evidence base is provided in support.
