Beyond just the type of lens and colour, goggle manufacturers apply additional technological features to their goggles in order to make them better at doing their job. We have gathered some of the most common lens features for you to have a look at when searching for a new goggle:
Quick lens changing
Although most available goggles allow you to changes lenses, manufacturers have come up with a variety of smart ways to make changing your lenses quick and easy. These quick lens changing systems often use special toggles and now even magnets. Although more expensive, they offer a very fast way of changing lenses and typically come with a second lens. Plus you won’t need to carry an extra pair of goggles.
Virtually all quality goggles have a kind of venting system built in, but some are better than others. Generally speaking, more venting is better in terms of preventing your goggle from fogging up. It’s, therefore, important to check that the goggle’s venting system is compatible with the shape of your helmet and doesn’t get blocked. Some of the newer goggles even have battery powered fans that bring in the fresh air and defog the goggles, keeping your lenses clear in all kinds of conditions.
Almost all the new goggles you can buy today, even the ones at the lower end of the price spectrum, have 100% UV protection. When you’re in the mountains, UV intensity increases with altitude and protecting your eyes from these harmful UV rays will prevent damage to your retinas. It also helps against eye fatigue.
A special hydrophilic chemical treatment on the inside of the goggle’s lenses can significantly reduce its tendency to fog. However some coatings are more durable than others, so make sure you read the manufacturers instructions because not knowing how to care for your goggle can lead to wiping off the anti-fog coating. Ventilation combined with a coating is the best anti-fog measure available today.
When light is reflected off certain surfaces, it tends to be reflected at higher intensity through angles that are perpendicular to the surface. Polarized lenses act as a filter of vertical light and are able to cut glare much more effective than a goggle’s standard mirrored lens. Furthermore, they also improve the overall visual clarity, provide increased contrast and will reduce eye fatigue and strain.
