    Of course, because the refractive index of water and air to light is different, if the lens surface of swimming goggles is uneven, it is like wearing a convex lens or a concave lens in water, which will cause damage to the eyes and affect the vision over time.

    If you wear swimming goggles for a long time, you may suffer from vision loss and fatigue. Due to the influence of water refraction, you should choose swimming goggles within 50 ~ 100 degrees lower than normal prescription when you buy them.
