Web17 de ago. de 2024 · This is because of the curved surface of the lens. According to Snell’s law of refraction, this makes the refraction higher. This causes the light to focus on the fovea, making images sharp underwater. The spherical lens also warps images. From our perspective. the way a fish sees its surrounding will be a bit curved.
