First of all, goggles are divided into cylindrical and spherical lenses:
Note: Polarised lenses prevent glare. Depth perception is also better, i.e. you can see bumps better.
There are also goggles with a lens change system. This means you can easily change the lenses yourself at any time, depending on the weather conditions. Practical, isn't it?
Your goggles steam over during your sessions? Then it's due to incorrect ventilation. So-called antifog coatings should be part of every good pair of goggles.
For those of you who wear glasses, there are of course goggles that can be worn over corrective spectacles. These goggles are labelled OTG (over the glass). In addition, the prescription can also be clipped directly into the goggle lens.
This factor is almost the most important of all. The frame of the goggles must fit into the recess of the helmet and be flush with the face. The gap between the goggles and the helmet must not be too large. It is best to choose goggles and helmet from the same manufacturer.
After this massive pile of information, you should finally have a clear vision. Stay up to date and ask the local experts in the shop for more information. See you on the mountain!
