There are a few key reasons why it’s recommended to wear goggles when swimming:

1. Eye protection – Swimming in pools or open water can expose your eyes to chemicals, debris, and other irritants. Goggles help shield your eyes and prevent stinging or irritation.

2. Improved vision underwater – Without goggles, your vision can be blurry and distorted underwater due to the refraction of light. Goggles correct this and allow you to see more clearly.

3. Comfort – Keeping your eyes open underwater can be uncomfortable, especially in chlorinated pools or cold open water. Goggles create a barrier to keep your eyes moist and comfortable.

4. Safety – Being able to see clearly underwater is important for safety, whether you’re swimming laps, playing water sports, or exploring underwater. Goggles help you navigate and avoid collisions.

So in summary, goggles are an essential piece of swimming gear that protect your eyes, improve your vision, increase comfort, and enhance safety in the water. They allow you to have a more enjoyable and safer swimming experience.
