Human beings have a natural curiosity about what goes on underwater; after traversing the entire surface of the world, the explorers turned their eyes downward, into the depths. It's tempting to open your eyes in the pool, even with that familiar chlorine sting that comes with the set. There are methods that will help you get used to this discomfort, but there are also legitimate health issues when opening your eyes underwater. Therefore, it is recommended that you wear swimming or diving goggles when you want to satisfy this natural curiosity, whether you are in the pool, on the beach or at the bottom of a lake.

Steps

Method 1 of 3: Opening Your Eyes Underwater

See Underwater Step 1

Step 1. Look inside your pool

This sounds simple, but anyone who has attempted this feat knows the burning sensation that accompanies eye opening in a chlorine-heavy pool. Fortunately, there are techniques at your disposal that can help you get those rough earthly eyes used to water. However, if they are not enough, it is recommended to opt for glasses as a tool to see yourself safely in the pool.

  • Practice at home, filling the sink or bathtub with water, holding your nose, dipping your face, and then opening your eyes. Start with chlorine-free or residue-free water sources so you can get used to the feeling of water in your eyes without any additional discomfort.
  • Chlorine pools are generally kept at a safe pH for swimming, usually between 7, 0 and 7, 6. This effectively kills bacteria, but not the various oils and fats we bring into the water; these body by-products are quite common eye irritants.
  • Although exposure to normal amounts of chlorine is irritating, it will not cause permanent damage. However, it will remove the protective film from the cornea, leaving the eyes more vulnerable to any bacteria that have survived in the chlorinated pool.
  • If your eyes get irritated, wash them with cool, cool water or use drops of saline solution to relieve the pain.

Step 2. Open your eyes to the open ocean

Swimming in a natural source of water means there's no chlorine to irritate the eyes, but adventurers should pay attention: if there's no chlorine, there's bacteria and debris. Near the shore, waves are constantly sending sand and small rocks toward the beach, increasing the possibility of debris streaking the corneas. Away from the shore, you will have a more pleasant experience opening your eyes in the water.

Be careful when opening your mouth too - while it doesn't look all that dangerous, a sip of seawater can contain millions of bacterial cells, tens of thousands of zooplankton and hundreds of thousands of phytoplankton

Step 3. Open your eyes on a lake

Bacteria are your main concern when opening your eyes in a freshwater lake. While there's no guarantee that you'll get in trouble with the lake's one-celled citizens, it's recommended that you wear some eye protection (swim or scuba goggles) if you want to see into the water. In shallow water, dirt and other harmful particles from the bottom of the lake can be kicked up as you swim and eventually get into your eyes.

  • Acanthamoeba is a particularly unpleasant amoeba that can be found in fresh water (including, in rare cases, tap water). Infections may even require a corneal transplant.
  • Lakes provide a more comfortable experience to see in the water than a chlorine pool or the turbulent edge of a beach. If you want to take that risk, you'll probably be able to keep your eyes open on the lake longer than on any other body of water! Remember, however, that poor visibility in lakes may not offer much to see.

Step 4. Take off your contact lenses

For any of the environments mentioned above, you must remove contact lenses before opening your eyes underwater. While there's a risk that they'll float around (although water pressure will likely keep them in place), the biggest danger lies in a bacterial infection.

If you wear glasses or contact lenses, it is possible to have the prescribed grade put on a scuba mask. Using it will be a much safer alternative to see what is underwater than opening your eyes, being excellent for those who cannot see well without glasses

Step 1. Put on diving goggles

The goggles allow you to clearly see what's in the water without any irritation, and the barrettes ensure they'll stay snug on your head while you swim. They are easy to attach: just place the lens over your eyes, then stretch the silicone strap to the back of your head. It will gently press your temples, like your glasses, but without any pain.

  • A pair of glasses is only good if there is a good seal. If water is entering the inner chamber, you might want to try another pair. The shape of the strap and lenses should do all the work for a good seal; you shouldn't have to repeatedly fix the positioning by pressing the glasses against your face.
  • Glasses are often worn by competitive swimmers who cannot afford to compromise their eyesight by being without them, or their speed by not wearing a more streamlined swimming mask.
  • First made from tortoise shells polished by the Persians in the 14th century to protect their eyes as they swam in search of pearls, water glasses have undergone significant changes since then. Modern variations offer excellent visibility and use a blend of plastic, silicone and polycarbonate.

Step 2. Wear a diving mask

The diving mask goes a step beyond swimming goggles as they also cover your nose. If you are uncomfortable blowing air through your nose, it avoids the need to plug it every time you go diving. Like goggles, diving masks are attached to the head by a single strap, wider than those on most goggles, and should remain on the face during swimming without any need to apply manual pressure.

  • Diving masks work well because of their flat surface and the space between the viewfinder and your eyes, allowing them to focus on what's in the water. Light bends differently in water than in air, and the mask design corrects this variation for you.
  • Snorkels can be attached to the straps of diving masks, allowing you to float across the surface of the water with unlimited access to good ol' clean air.
  • If you wear goggles, it is also possible to apply degrees on the diving mask's display. Diving with contact lenses is also possible, although you should stick to soft lenses if you're out in the open ocean. Rigid lenses can be painfully pressed against the eyes at greater depths.

Step 3. Practice diving

Diving with the aid of an oxygen tank (or a tank containing another suitable mixture of compressed gas) is also known as SCUBA (or scuba) diving. Practitioners are equipped with scuba masks, swimsuits, flippers and wetsuits to move better as they explore seabeds, shipwrecks, corals and caves. Look for a certified diving program near you if you are interested. There are specific safety information that must be understood in order to minimize risks when diving in underwater environments that humans cannot inhabit.

  • Swimsuits absorb and retain a layer of water that will be heated by your body, keeping you warm. The temperature drops a lot in deeper places.
  • Fins give divers faster propulsion, which is much needed considering the other gear they use.
  • The wetsuit works by inflating and deflating the suit with air to control the depth to which you will float in the water. Weights are also used to aid in descent.
  • Barriers can be either natural (involving large coral networks) or artificial (structures that were created or deliberately sunk by man).

Step 1. Sail on a boat with a clear floor

Designed to allow crew members to see the water beneath them, these boats often pass corals, wrecks or other watery berths. Tours on these boats are usually relatively inexpensive compared to other underwater exploration methods and operate in several coastal cities and natural water sources.

Step 2. Get into a submarine

Although this is not a possible option for most people (except when buying a DVD of The Hunt for Red October), as luxury personal submarines start to be sold from R$2.5 million, submersible and military vehicles how civilians patrol and probe the depths. Tours in non-operational military submarines are possible to enter this underwater world, and several agencies in tourist destinations offer such an underwater option for tourists.

When discussing submersible platforms, there are human operated vehicles (HOV) and remotely operated vehicles (ROV). The US National Oceanic and Atmospheric Administration page contains information detailing several submarines used by researchers today (both HOVs and ROVs), including a model called the “Alvin” which has been in use since 1964

Step 3. Walk along the beach

Scanning the beach for shells, hedgehogs and shark's teeth gives us a unique and quite peculiar view of the underwater world. It's kind of mysterious, if you think about it, considering that most of what goes ashore is dead or dying, but humanity has already learned a lot from the sea from what gets stuck on the shore. In fact, until the last century, this is how we have accumulated most of our knowledge about the ocean.

  • An adult giant squid was not even photographed until 2012. We only knew of its existence because of the squid pieces that ran aground on the beach or found them in the stomach of sperm whales that were trapped on the shore (unbelievable as it may seem, anecdotal evidence presented by ancient sailors were unfortunately not considered as evidence).
  • Beach walks anywhere can result in unique encounters with the unknown. Residents of Oxnard, Calif., along with those of other cities on the North American Pacific coast, came across a sea creature completely foreign to them (and most people) when massive amounts of Velella velella (a species of jellyfish) were found. on its beaches.
