Episode notes
Week Without Glasses
- David King Dunaway removed his glasses for a week despite being highly nearsighted to understand life without them.

Glasses Emerged With Reading Culture
- Lenses and magnifiers existed for millennia but eyeglasses as binocular devices emerged in 13th-century Italy among monks and scribes.
- Early glasses spread with increased literacy and printing because reading demanded close vision.
Church Resistance Shaped Early Attitudes
- The medieval Catholic Church often resisted spectacles as altering God's design and threatening its authority over knowledge.
- As printing and literacy spread, demand for reading glasses rose despite initial religious objections.
