Preventing fogging
Almost all of our glasses already have an anti-fog coating, which significantly increases the comfort of wearing them. This is why it is important not to touch the inside of the glasses unnecessarily, as this can accidentally wipe off this important coating.
(Competition series glasses may use Swipe Antifog technology, where the instructions say to wipe the inner surface to reveal a new coating. However, this does not apply to other glasses.)
The anti-fog treatment will wear off over time. In this case, the best maintenance measure is to spray the lenses with Arena or Speedo anti-fog spray, which will renew the anti-fog coating on the lenses. It is best to spray the lenses at home, when there is no moisture on the surface of the lenses yet.
Glasses storage
Glasses should be stored in a protective bag or case designed for them. This will prevent the glasses from being scratched and worn out to the point of being unusable. You can view the best way to protect your glasses, i.e. cases, on this page.
