How Did Ancient Humans Survive Without Glasses

Most of human history unfolded without a single pair of glasses, yet ancient people weren't functionally blind, they simply faced a completely different set of vision problems shaped by outdoor living, aging, infection, and light. This video explores the real science and archaeology behind how ancient humans coped with failing eyesight, from sunlight's effect on preventing nearsightedness to Egyptian eye medicine, ancient cataract surgery, and Inuit snow goggles engineered a thousand years before modern optics. This video is created for educational and historical purposes only, drawing on peer-reviewed vision science and archaeological research. It does not constitute medical advice regarding eye health, myopia prevention, or vision correction; consult a licensed eye care professional for any concerns. Historical medical practices described are not recommendations for treatment. #AncientHistory #VisionScience #Archaeology #HumanEvolution #Ophthalmology
