How do I assemble the goggles?

To assemble the goggles, thread the string provided through each hole on the far side of the goggles.

If the hole does not appear open, then poke a pointed instrument, for example a pen, through the hole to displace the plastic.

Once threaded through the hole, tie a knot directly to secure the string to the goggles on each side. 

Press the release button on the slider to tighten/loosen the goggles. Place the goggles over your head and tighten the slider until the googles fit comfortably.
