Visual Impairment Statistics

See how cataract treatment can restore sight to millions, while the costs and gaps in access still leave vision loss striking hard on daily life and economies, including an estimated 3.0% of global YLDs in 2019 and $139 billion in annual U.S. productivity losses. You will also find the latest market signals and practical fixes side by side, from low vision rehabilitation and teleophthalmology reducing travel by up to 40% to the fast scaling of vision care and assistive technologies supported by current device and accessibility market estimates.

Vision impairment is far more measurable than most people realize and the latest analyses put hard figures behind every claim. For example, cataract can be treated with surgery and restore sight, yet 7.0% of the world still has 20/30 or worse vision. At the same time, the economic and market trail is just as striking, with global vision care valued at $216.1 billion in 2022 and vision loss costing the US economy $139 billion each year, so the question becomes why unmet needs and avoidable barriers persist.
