TED-Ed: A curable condition that causes blindness - Andrew Bastawrous

Cataracts are a common eye condition, especially in older adults, caused by protein clumping in the lens. Historically, treatments like couching were risky and often ineffective. Modern advances, inspired by Sir Harold Ridley's work, involve implanting artificial lenses, significantly improving outcomes. Despite these advances, many remain blind due to limited healthcare access and awareness. Efforts to increase education and provide affordable surgeries are crucial for addressing this issue.
