Walking on a sunny day with the Sun elevated at 30 to 45 degrees poses a potential risk for vision damage if one continues to look at it despite discomfort. The natural reaction to glare typically involves tilting the head down, which helps shield the eyes. This situation is common while driving, where the Sun's position can obstruct visibility. Sunglasses are designed not only for comfort but also to prevent potential retinal damage from prolonged exposure to bright sunlight. The discussion highlights a common misconception about sunglasses, emphasizing their protective role rather than just comfort. References to scientific studies or medical guidelines on this topic were requested but not provided in the discussion.
