If you want to know how to open your eyes underwater without that stinging, blurry misery, here’s the honest headline first: you almost never need to — goggles let you see clearly with zero sting, and that’s what nearly every swimmer uses. But opening your eyes bare is a handy backup skill, so this guide covers how to do it comfortably, whether it’s safe, and the real goggles-vs-no-goggles verdict.

The short answer

To open your eyes underwater, start in a clean pool with goggles to build confidence, then try brief bare-eyed opens, blinking gently and keeping them open only a second or two at first. It’s safe for short periods, though chlorine can leave your eyes red and irritated. But honestly: most people should just wear goggles. They eliminate the sting, let you see clearly, and make swimming far more relaxed. Bare-eye opening is an optional backup, not a requirement.

The honest goggles vs no goggles verdict

Let’s settle this plainly:

  • For everyday swimming, wear goggles. They let you see clearly, remove the stinging that makes beginners tense and flinch, and make the whole experience calmer. There’s no bravery points for suffering through blurry, burning eyes. If you’re still choosing a pair, see the best swim goggles for beginners.
  • Bare-eye opening is a useful backup. It’s worth being able to open your eyes underwater — for safety, if your goggles flood, or for open water where you might not wear them. But it’s a nice-to-have, not a must.

So: default to goggles, and treat bare-eye opening as a bonus skill.

Why it stings (and why it’s not the water’s fault)

That sharp sting in a pool is mostly from the chemicals used to keep the water clean and the water’s pH — not the water itself. That’s why:

  • Pool water tends to sting the most.
  • Salt water (the ocean) stings less because it’s closer to the natural saltiness of your tears.
  • Fresh water (lakes) is usually gentlest on the eyes, though clarity and cleanliness vary.

Opening your eyes briefly won’t damage them, but chlorine can leave them red, dry, or irritated for a while afterward. Goggles simply skip all of that.

How to open your eyes underwater comfortably

If you want to build the skill, go gently and in a clean pool:

  1. Start with goggles on. Get comfortable seeing underwater with clear vision first — it removes the fear of the unknown.
  2. Then try brief bare opens. With your face under, open your eyes for just a second, then close. Repeat, extending a little each time.
  3. Blink, don’t strain. Relax your face and blink gently rather than forcing your eyes wide.
  4. Look around calmly. Once a second or two feels okay, practice glancing around so it becomes natural.
  5. Rinse after. If your eyes feel irritated, rinse with clean fresh water afterward.

Being comfortable with your face in the water at all comes first — if that’s still hard, start with how to put your face in the water.

Important: contact lens wearers

If you wear contact lenses, take extra care:

  • Water can wash your contacts right out, and
  • more seriously, it carries a small but real risk of a serious eye infection for lens wearers.

So if you wear contacts, wear goggles (prescription goggles are a great option), and keep your eyes closed if water does get behind them. Don’t practice bare-eye opening with contacts in.

A quick safety note

This is general guidance, not medical advice. Brief bare-eye opening in a clean pool is fine for most people, but if you have eye conditions, wear contacts, or get persistent redness, irritation, or pain, wear goggles and check with an eye-care professional.

The next small step

Do the easy thing first: get a comfortable pair of goggles and enjoy seeing clearly underwater with no sting. Once that’s second nature, add a few brief bare-eyed opens at the end of a session as a backup skill. Clear vision underwater — however you get it — makes everything about swimming calmer.
