- • Stay strictly in shallow water where you can comfortably stand up at any time.
📋 Step-by-Step Guide (5 Steps)
Master the Hand-Seal Technique on Dry Land
Stand before a mirror and curl your dominant hand into a loose, airtight fist or cupped shape with your index finger and thumb forming an 'O' ring. Press the base of your palm firmly against your cheekbone and your curled fingers against your eyebrow ridge to create an airtight pocket over one eye. Test the suction by gently inhaling through your nose; you should feel a distinct seal around the eye orbit without pressing directly onto the eyeball.
- • A tight, uniform skin-to-skin contact ring around the eye socket without gaps.
- • Pressing knuckles into the eyelid instead of resting on the surrounding facial bones.
- • Leaving gaps between fingers where air will immediately escape.
Submerge Face While Trapping the Air Bubble
Take a calm, normal breath and lean over the water with your face tilted downward parallel to the surface. Position your cupped hand securely over your eye before your face enters the water, keeping the pocket inverted like an upside-down cup. Lower your face into the water smoothly while holding the hand seal rigid so the trapped bubble cannot float upward and escape.
- • Submerged face with a visible air pocket held captive against your eye socket.
- • Tilting head backward before submerging, which allows the bubble to bubble up and vent out.
- • Entering the water too quickly and dislodging the hand seal.
Open Your Eye Inside the Trapped Bubble
Once fully submerged, slowly open your eye inside the sealed chamber without shifting your hand pressure. Because light is passing from water through the flat interface of the trapped air bubble into your cornea, your eye can focus light normally rather than scattering it. Observe the underwater environment with sharp, goggle-like clarity while keeping your hand perfectly still.
- • Clear, focused vision of pool bottom or underwater objects through the trapped pocket.
- • Opening the eye before establishing the seal, flooding the chamber with water.
- • Blinking rapidly, which breaks the delicate water-air boundary.
Use the Clear Cup Inversion Method for Dual-Eye Viewing
Take a small, clean, rigid clear plastic cup and hold it vertically upside-down so the rim points directly downward. Submerge the cup completely into the water while keeping it strictly level, preserving the trapped column of air inside. Press the open rim gently against your brow and cheekbones, look straight into the clear bottom, and enjoy a wider, binocular field of view.
- • A dry, clear viewing chamber inside the cup holding back the surrounding water.
- • Tilting the cup sideways during entry, causing the trapped air bubble to burp out.
- • Using a cup with rough, sharp plastic edges against facial skin.
Surface, Clear Water, and Flush Eyes
Lift your head smoothly above the water surface before releasing your hand or cup seal. Gently dab excess water from your eyebrows and eyelids with a soft towel to prevent chlorine or pool chemicals from dripping down into your eyes. If your eyes feel dry or slightly irritated from accidental splashes, apply a few drops of sterile saline or artificial tears.
- • Dry eyelids with no residual pool water running into eyes.
- • Rubbing eyes vigorously with hands or rough towels immediately after surfacing.
- • Releasing the air seal while still underwater with your eyes wide open.
