It sounds simple, but anyone who's tried it knows the sting that accompanies opening your eyes in a heavily chlorinated pool. Luckily, there are techniques available to acclimate your land-lubber's eyes to the water. If those techniques don't prove satisfactory, however, it's recommended you turn to goggles or dive masks as a tool to safely see in the pool.  Practice at home by filling your sink or bathtub with water, plugging your nose, submerging your face, and then opening your eyes. Starting with water sources free of chlorine or debris will help you get use to the feeling of water on your eye, without additional discomfort. Chlorinated pools are generally kept at a safe-for-swimming pH level of 7.0 to 7.6.  This effectively kills bacteria, but not the various fats and oils we bring into the pool; these accumulated bodily byproducts are common eye irritants. While exposure to normal amounts of chlorine is irritating, it will not cause permanent damage. It will, however, wash the protective tear film away from your cornea, actually making the eye more vulnerable to any bacteria which has survived the chlorinated pool.  If your eyes become irritated, flush them with cool, fresh water, or utilize saline drops to ease the pain. Swimming in a natural source of water means no chlorine for eye irritation, but prospective eye-openers should be aware: no chlorine equals “yes” to bacteria and debris. Near the shore, waves are constantly throwing sand and small rocks toward the beach, making corneal scratches from debris a possibility. Away from the shore, you'll have a more pleasant experience looking around underwater. Careful about opening that mouth, too—while they're not all as strictly harmful as they may sound, one gulp of seawater can contain millions of bacterial cells, tens of thousands of zooplankton, and hundreds of thousands of phytoplankton. Bacteria is your major concern when opening your eyes in a freshwater lake. While it's far from a given that you'll have problems with the lake's single-cell citizens, it's recommended you use eye protection (goggles or a dive mask) when you want to see underwater. In shallower water, dirt and other hazardous particles from the lakebed can be kicked up while swimming and enter your eye.  Acanthamoeba is one particular nasty amoeba that can be found in fresh water (including, rarely, tap water). Infection can necessitate a cornea transplant.   Lakes do provide a more comfortable experience for opening your eyes than a chlorinated pool, though, or the turbulent shoreline of beach. If you're willing to risk it, you can probably keep your eyes open longer here than in any other body of water! The dismal visibility in a lake, however, might not provide too much to see. In any of the above-mentioned environments, you'll want to remove your contact lenses before opening your eyes underwater. Although it's a bit of a risk for the lenses to float away (thought the water pressure will likely keep them in place), the greater danger is bacterial infection.  If you wear glasses or contact, you can have your prescription put into a dive mask. Wearing a dive mask is a much safer alternative for seeing what's underwater than opening one's eyes, and is optimal for anyone who would be unable to see very well without their glasses.
See the inside of your swimming pool. Open your eyes in the open ocean. Look under a lake. Take your contacts out.
Sammanfatta den här artikeln i en mening. Det låter enkelt, men alla som har provat det vet vad som händer när man öppnar ögonen i en kraftigt klorerad pool. Som tur är finns det tekniker tillgängliga för att acklimatisera dina landklubbers ögon mot vattnet. Om dessa tekniker inte visar sig tillfredsställande rekommenderas dock att du vänder dig till skyddsglasögon eller dykmasker som ett verktyg för att säkert se i poolen. Träna hemma genom att fylla handfatet eller badkaret med vatten, täppa till näsan, doppa ansiktet och sedan öppna ögonen. Börja med vattenkällor fria från klor eller skräp kommer att hjälpa dig att få användning för känslan av vatten på ögat, utan ytterligare obehag. Klorinerade bassänger hålls i allmänhet på en säker för simmande pH-nivå på 7,0 till 7,6. Detta dödar effektivt bakterier, men inte de olika fetter och oljor som vi för in i bassängen; dessa samlade kroppsliga biprodukter är vanliga ögonirriterande. Även om exponering för normala klormängder är irriterande, kommer det inte att orsaka permanenta skador. Det kommer dock att tvätta bort den skyddande tårfilmen från hornhinnan, vilket faktiskt gör ögat mer sårbart för alla bakterier som har överlevt den klorerade poolen. Om dina ögon blir irriterade, spola dem med kallt, sötvatten, eller utnyttja saltlösning droppar för att lindra smärtan. Att simma i en naturlig vattenkälla innebär inget klor för ögonirritation, men potentiella ögonöppnare bör vara medvetna: inget klor är lika med ”ja” med bakterier och skräp. Nära stranden kastar vågorna ständigt sand och små stenar mot stranden, vilket gör korneala repor från skräp till en möjlighet. Borta från stranden får du en trevligare upplevelse av att se dig omkring under vattnet. Var försiktig med att öppna munnen också – medan de inte alla är så strikt skadliga som de kan låta, kan en droppe havsvatten innehålla miljontals bakterieceller, tiotusentals zooplankton och hundratusentals fytoplankton. Bakterier är ditt största bekymmer när du öppnar ögonen i en sötvattensjö. Även om det är långt ifrån givet att du kommer att få problem med sjöns encelliga medborgare, rekommenderas att du använder ögonskydd (goggles eller en dykmask) när du vill se under vattnet. I grundare vatten kan smuts och andra farliga partiklar från sjöbottnen sparkas upp medan man simmar och kommer in i ögat. Acanthamoeba är en särskild otäck amöba som kan hittas i sötvatten (inklusive, sällan, kranvatten). Infektion kan göra det nödvändigt med en hornhinnetransplantation. Sjöar ger dig en bekvämare upplevelse när du öppnar ögonen än en klorerad bassäng eller en turbulent strandlinje. Om du är villig att riskera det, kan du förmodligen hålla ögonen öppna längre här än i någon annan vattensamling! Den dystra sikten i en sjö kanske dock inte ger alltför mycket att se. I någon av de ovan nämnda miljöerna vill du ta bort dina kontaktlinser innan du öppnar ögonen under vattnet. Även om det är lite av en risk för linserna att flyta bort (tros vattentrycket kommer sannolikt att hålla dem på plats), desto större fara är bakteriell infektion. Om du har glasögon eller kontakt kan du få ditt recept inlagt i en dykmask. Att bära dykmask är ett mycket säkrare alternativ för att se vad som är under vatten än att öppna ögonen, och är optimalt för alla som inte skulle kunna se mycket bra utan sina glasögon.
