Myopia

When I was 13 I didn’t need glasses but marveled at the experience of those who did. I thought people with myopia could see things two ways, with and without glasses. Poor eyesight seemed like a blessing that could lead to interesting insights.

This might be the case.

With myopia, one realizes they don’t know what they are looking at. This arouses curiosity which exercises the mind.

A well-exercised mind is fitter.

Statistically, people who are myopic have a higher IQ than those who are not.
