February 7, 2019<\/strong><\/p>\n By Tim Fricke, BOptom, MSc<\/strong> Eye care practitioners see the burden of myopia in individuals every day: patients worrying about refractive changes; patients needing to update glasses and\/or contact lenses to recover vision lost to myopia progression; patients with myopia-associated pathology and\/or vision loss from those conditions; parents who worry about their children becoming myopic and progressing to higher levels of myopia, etc. These personal burdens also have some community-level implications via their effect on health expenditure, quality of life and productivity. However, the significant public health implications of myopia and high myopia are ones that clinical eye care practitioners do not see every day because they are in people who do not access eye care.<\/p>\n Vision impairment is associated with profound changes in quality of life and productivity.1-6<\/sup> There are two main ways myopia can cause vision impairment, each of which can happen between regular visits to an eye care practitioner but are more common in people who never, or irregularly, attend for eye care. The first way myopia can cause vision impairment is via un- or under-corrected refractive error \u2013 distance vision impairment can result when a person with myopia is unable to obtain appropriate spectacles or contact lenses or have them updated as needed.7-10<\/sup> Secondly, increasing myopia is associated with increasing prevalence of vision impairment from pathological complications including glaucoma and vitreoretinal diseases.11-13<\/sup><\/p>\n It is broadly agreed that myopia is common and rapidly increasing over time.14,15<\/sup> Interestingly, the demographics of people with myopia appears to be changing in two ways that are important in the link between myopia and vision impairment:10,13,14<\/sup><\/p>\n There are barriers that prevent some people in any community from accessing adequate vision care and correction. Globally though, people are less likely to have sufficient optical correction, or access to healthcare able to adequately manage myopia complications, if they are older and\/or live in rural areas of less developed countries.10,13<\/sup> We have estimated that there were 480 million people worldwide in 2015 who experienced vision impairment from uncorrected myopia,10<\/sup> and that there were 10 million people worldwide in 2015 who suffered vision impairment due to myopic macular degeneration.13<\/sup> These estimates are substantially larger than vision impairment estimates for any other condition,9<\/sup> suggesting that myopia was the leading cause of vision impairment in the world in 2015.<\/p>\n
