The Importance of Goggles for Underwater Vision
Wearing goggles while swimming is crucial for maintaining clear vision underwater. Unlike on land where the cornea and lens work together to form an image, underwater the cornea does not refract light effectively due to its similarity to water. Human lenses compensate but can lead to blurry vision. Fish, with spherical lenses, are adapted to underwater vision. Goggles create an air barrier, allowing eyes to refract light properly, enhancing underwater sight.
