Even back in the days of Captain Scott and the race to the South Pole, people realised that snow could be bad for your eyesight. Scott and co. may have finished a plucky second (in the approved British fashion) and died in the attempt, but at least they had goggles to stop themselves from getting snow-blindness. Today’s goggles thankfully are more sophisticated than Scott’s, which apparently had lenses “cut from a piece of wood” (no joke!) but they essentially serve the same purpose – to protect your eyes from the glare of reflected sunlight. Here we test four of the finest pairs available.
