The most important swimming accessory you will need is a pair of swimming goggles. The prime consideration when buying swimming goggles is that they should fit properly and be comfortable to wear. They should have a reliable seal to prevent leaks from sea water or chlorine which is an irritant . They should not leave red suction rings on the face when they are removed.
Quick tip for fitting goggles
Place the goggles on a dry face without using the head strap.
Apply a small amount of pressure and the goggles should stay in place.
You will love swimming goggles that fit well and do not need to be adjusted during swimming lessons. Goggles which have anti fog lenses to prvent misting are preferable. These goggles are generally a little more expensive than those without anti fog coating.
