Ngokuthuthukiswa kwezinga lokuphila kwabantu kanye nokuthuthukiswa kwezidingo zokunakekelwa kwamehlo, isidingo sabantu sokuhlobisa izibuko nokuvikelwa kwamehlo siyaqhubeka nokwanda, futhi isidingo sokuthengwa kwemikhiqizo yezibuko ehlukahlukene siyaqhubeka sikhula. Isidingo somhlaba wonke sokulungiswa kwe-optical sikhulu kakhulu, okuyisidingo esiyisisekelo semakethe esisekela imakethe yezibuko. Ngaphezu kwalokho, ukuguga kwesibalo sabantu emhlabeni wonke, ukwanda okuqhubekayo kwezinga lokungena kanye nesikhathi sokusetshenziswa kwemishini ephathwayo, ukuqwashisa okukhulayo kwabathengi ngokuvikelwa kwamehlo, nemiqondo emisha yokusetshenziswa kwezingubo zamehlo nakho kuzoba amandla abalulekile okuqhuba ukwanda okuqhubekayo imakethe yezingubo zamehlo emhlabeni jikelele.
Njengoba kunenani elikhulu labantu eShayina, amaqembu obudala ahlukene anezinkinga zokubona ezingase zibe khona, futhi isidingo sokusebenza semikhiqizo yezibuko namalensi sikhula usuku nosuku. Ngokwemininingwane yakamuva yeNhlangano Yezempilo Yomhlaba kanye neSikhungo Sokuthuthukiswa Kwezempilo SaseChina, inani labantu abanenkinga yokubona emhlabeni lilinganiselwa ku-28% yenani labantu, kuyilapho ingxenye yaseChina ifinyelela ku-49%. Ngokuthuthuka okuqhubekayo komnotho wasekhaya kanye nokuthandwa kwemikhiqizo ye-elekthronikhi, izimo zokusebenzisa amehlo abantu abasha nabadala ziyanda, futhi isizinda sabantu esinenkinga yokubona siyakhula.
Ngokombono wenani labantu abane-myopia emhlabeni, ngokusho kwesibikezelo se-WHO, ngo-2030, inani labantu abane-myopia emhlabeni lizofinyelela cishe ezigidini eziyizinkulungwane ezingu-3.361, lapho inani labantu abane-myopia ephezulu lizofinyelela cishe 516 million. Sekukonke, isidingo esingaba khona semikhiqizo yengilazi yomhlaba wonke sizoba namandla ngokuzayo.
