The Nike Max Speed Tint lens is designed to optimize visual performance during sports like running and cycling by quickly responding to changing light conditions.
We tried out the space-age sounding Skylon Ace model, which comes with interchangeable lenses, whilst out mountain biking and found that they made a definite difference when moving in and out of light and dark areas such as woodland, as well as being adaptable enough to wear from dawn until dusk as the light conditions vary.
In addition these are lightweight sunnies with frames specifically engineered for sport performance, featuring a lightweight sport-wrap frame design, secure-wrap temple arms and a ventilated nose bridge; you hardly notice you're wearing them.
Fair enough they're pricey, but they are all-singing, all-dancing and will work or pretty much any activity you care to indulge in.
