> "I don't see the risk of gouging my eyes out as being very high" You're absolutely right about this. The risk is very low. But the stakes are extremely high. It's the insurance problem: how much are you willing to pay to prevent a rare but extremely hazardous even in the future? To a lot of people (maybe most) wearing glasses if they don't need correction seems silly. I can't argue with that, but in my case, my sunglasses saved me from an expensive, painful surgery and possible disability. The experience made me feel that the "insurance" of wearing glasses habitually was an acceptable cost to bear if it could keep that from happening again. I'm no actuary; it really is just a feeling. And feelings are what all of us rely on most when we evaluate risk, whether we like it or not. My feeling is not likely any more valid than yours, because it's based on my values and experiences, and your's may be entirely different. Now, its totally possible for these extra barriers to interfere with one's life. Again I think about how many kids are discouraged from riding bikes because of the oppressive safety gear. Or suppose I miss a plane because I can't find my fake glasses. When that happens it'll be time to question whether my reliance on my protective barriers is healthy. I think that's the issue your comments anticipate, and you're right about that too.
