Inequality in Vision Loss


The risk of vision loss increases as you age.

Cataract, presbyopia, age-related macular degeneration and glaucoma are all associated with ageing.

By 2050, it is anticipated that the proportion of the world’s population aged 65 years and over will double, increasing the prevalence of vision loss caused by these conditions.

However, most vision loss can be avoided with access to eye care services.

The Global Coalition on Aging’s International Vision Health Scorecard

The Scorecard explores how the following countries perform in distinct, yet interconnected categories that contribute to vision health and aging.

The categories are:

  • National Commitment and Investment: including funding levels, national-level focus, and the commitment to robust, consistent data collection.
  • Research and Innovation: considering the strength of IP protections, R&D funding, and the use of technology in diagnosis and care.
  • Health System Preparedness: weighing a country’s capacity, the skills of its workforce, and its responsiveness to patients—in an effort to advance patient-centered care.
  • Access: considering wait times for consultations and treatment, the distribution of the eye care workforce, and the cost of care.
  • Prevention: weighing the coordination of care, interventions to reach at-risk populations, and efforts to increase awareness of eye diseases and symptoms.
  • Societal Support: how well a country supports people with vision loss and prepares for demographic shifts, including non-discrimination policies and the development of age-friendly communities.

For more information on each category, please view the full International Vision Health Scorecard.

The individual category scores, in turn, determine the country’s overall score – all are listed in the following table (scroll right to view all six categories). The overall scores are also listed in the Vision Atlas country dashboard.

The Scorecard’s findings and calls to action aim to spur meaningful progress to improve vision health and ultimately advance healthy aging, enabling more people to remain active and productive for more years of their lives.
