The Blaze 2.0 over your prescription glasses

OTG stands for “Over The Glasses”. The Blaze 2.0 has side cut-outs for the arms of your prescription glasses and enough depth inside so your frame doesn’t press against the goggle lens. Here’s how to find out whether your frame fits underneath.

  • 14 cm

    Width of your frame

    Prescription glasses up to about 14 cm wide usually fit underneath, as long as the arms sit close to your head. Details

  • 18 cm

    Temple to temple

    At about 18 cm wide on the outside, the Blaze 2.0 should ideally reach your temples or extend just slightly beyond them. Fit guide

  • 10 cm

    Field of view and helmet brim

    The field of view is up to 10 cm high. The top of the goggle frame should follow the helmet brim: if a finger fits between them, the combination isn’t ideal. Fit guide

Will my frame fit underneath?

Four things decide whether your prescription glasses fit under the Blaze 2.0. The drawing shows the goggle and the glasses from the front and from above.

Arrow 1 measures the frame on the outside from arm to arm; up to about 14 cm it usually fits underneath. Arrow 2 measures the goggle on the outside, about 18 cm. Top view: arrow 3 shows the gap between the prescription lens and the goggle lens; they do not touch. Arrow 4 shows the arms beside the temples: close to the head, without the goggle pressing them against the temples. Front 1 up to about 14 cm 2 about 18 cm Top 3 4

What to check on your frame

  1. Measure your frame from arm to arm. On the outside at the widest point, from the outer edge of one arm to the outer edge of the other.
  2. Up to about 14 cm, it usually fits underneath. Provided the arms sit close to your head. The Blaze 2.0 itself measures about 18 cm across the outside.
  3. The lenses must not touch. There must be a gap between the prescription lens and the goggle lens – contact means scratches on both lenses.
  4. The arms must not press against your temples. So tighten the strap just enough that nothing shifts when you shake your head – not a millimetre tighter.

Try it on in five minutes

Use your own prescription glasses and your own helmet. Without both, trying it on tells you nothing.

  1. Wear the whole set-up. Prescription glasses, helmet and goggle together – the strap goes on the outside, over the helmet.
  2. Check whether the lenses touch. If they do, both lenses get fine scratches and the anti-fog coating suffers.
  3. Tighten the strap only as much as you need to. Too tight, and it presses the arms into your temples – after an hour, your head hurts.
  4. Shake your head. Side to side, then forwards and back. If anything shifts, the set-up isn’t right yet.

Why goggles fog faster for glasses wearers

With prescription glasses, four surfaces instead of two sit in the airflow: the outside and inside of the goggle lens plus both sides of your own lenses. In practice it’s usually the prescription glasses that fog first, not the goggle – they sit closer to the rising warm breath.

  • Wear your buff or neck warmer below the goggle, never pulled up over your nose and tucked under it. Otherwise your warm breath rises straight into the goggle.
  • Keep the vents clear of your beanie, hood and helmet brim.
  • If in doubt, treat your prescription glasses with an anti-fog product, not the goggle.
  • Don’t push the goggle up onto your helmet when it’s snowing or while you’re waiting at the top of the lift. Wet foam is often why a goggle fogs up in the afternoon.

Three common mistakes

  • Bringing your widest frame. If you have the choice, take the prescription glasses with the narrowest frame and the thinnest arms you own when you go skiing.
  • Forgetting the helmet. If you try it on without a helmet, you won’t notice: a helmet that pushes the goggle down slightly passes that pressure straight on to the frame of your prescription glasses.
  • Wiping the inside. Dab moisture on the inside with a microfibre cloth – never wipe. Only once the lens is completely dry should you gently clean off smudges.

What’s in the box

The Blaze 2.0 comes with two lenses and a case. Both lenses are cylindrical and swap magnetically, no tools needed. The Low Light lens with 76% light transmission comes with every colour, so one goggle covers both sunshine and snowfall.
