Did you know that penguins wear sunglasses?
Penguins that live in the Antarctic experience intense glare from polar sunlight. Yet, they have clear vision. Why? Within their retina are colored droplets of oil, and these droplets filter out blue and ultraviolet colors which allow penguins to experience no glare and enhanced visual sharpness. Researchers are now copying the penguin’s orange-colored filters to produce improved welding masks. Today’s masks are orange in color rather than the older dark shields which obscured vision. Pilots, skiers, and sailors all utilize orange tinted sunglasses and find improved vision in bright sunlight, fog, or haze. Why is the color orange a useful light filter? Orange tinted sunglasses reduce or eliminate blue light, which is a major component of glare. Eye damage is also minimized by the orange filter’s blockage of the UV light.
When we face a problem, such as not being able to see well in bright sunlight, we should stop and think: “Does something in nature have the same problem?” Observe how God solved it, and then copy God’s solution! God is the master designer, the master problem solver. He solved the polar glare problem, and He can solve our problems.
