New Zealand brand Blueseventy's Hydra-Vision may be larger than your average pool swimming goggle yet they remain streamlined enough to be drag-efficient.
They come with a variety of lens options to suit all types of light conditions, with our preference being to opt for a transparent or slightly tinted lens to prevent glare from the come the typically early start of race day.
Neat features include anti-fog properties and flexible lenses for the melee that commences as soon as the starter's horn blows. Our only negatives against the Hydra-Visions are that the lenses were too close to the eye, which obscured vision slightly due to our eyelashes being pushed against them. And we would'e preferred a less stiff strap to improve comfort.
