The world’s leading cause of vision impairment is “uncorrected myopia and hyperopia” | What is SPECS 2030, the WHO initiative?

Information current as of September 2, 2026.

Do you know the leading cause of vision impairment worldwide?

The answer is not a disease. According to the WHO (World Health Organization), uncorrected refractive error--in other words, nearsightedness or farsightedness that should be correctable with glasses or contact lenses but is left unaddressed is considered the leading factor in vision impairment worldwide. Even though glasses offer a simple and inexpensive solution, there are vast numbers of people around the world who still cannot access them.

WHO’s “SPECS 2030” Initiative

In response to this issue, the WHO is promoting “SPECS 2030,” an initiative to deliver glasses to people who do not have access to correction. In September 2026, a series of expert meetings were held, and preparations are also underway for a global status report on eye care and vision impairment. Vision is now one of the themes at the forefront of global health challenges.

What This Suggests for Those of Us Living in Japan

In Japan, glasses and ophthalmology clinics are familiar and accessible. But “somehow leaving difficulty seeing as it is” is, in fact, a habit shared around the world. Now that the time we spend looking at smartphone and computer screens is longer than ever, regularly checking the condition of our eyes may be one of the basics for maintaining our daily well-being. If you notice any concerning changes, please consider having an eye examination.

The everyday fact of “being able to see” is not something everyone in the world can take for granted. Simply knowing that fact can change our sensitivity toward health. In our health and medical section, we will continue to share the current state of global health based on primary information.
