To protect against potential eye injury in a wipeout, the material that the frame and lenses is made from are crucial considerations. Our Typhoon and Surge frames are both constructed using Grilamid TR90, a Swiss polymer which will never shatter / break into pieces on impact. Our proprietary lenses for the Surge and Zeiss lenses for the Typhoon are also shatterproof. The lenses cannot be pushed inwards towards the eye on impact owing to the way in which the lens retention grooves are designed. When it comes to a heavy impact, suitable frame and lens materials will spread the impact load. We recently blogged a case study on this very point which you may find interesting - https://www.lip-sunglasses.com/2019/03/ ... rotection/kite_hh wrote: ↑Tue May 14, 2019 4:31 amMy biggest worry with sunglasses is that they may break upon impact and pieces of it could enter the eye and cause permanent damage.Toby wrote: ↑Wed May 08, 2019 6:54 pmWe should be wearing sunglasses throughout the day and especially while kiteboarding! Why aren't we?
Just like with helmets, wearing sunglasses while kiteboarding seems unfashionable and excuses like “I will lose them”, “They are annoying”, “They are expensive”, “Water droplets on the lens bother me” and so on, seem to always come up.
The use of polarized sunglasses, in general, will help reduce the chances of cataracts, macular degeneration, sunburn on the cornea and the risk of experiencing vision issues like “snow blindness” which can and have happened to kiters before.
Regarding the OP: What makes polarized sunglasses special or superior to 100%UV protected ones with regard to eye protection?
As to the benefits of polarisation, this is about reducing glare and has nothing to do with UV protection. As has been pointed out elsewhere in this thread, low quality sunglasses with poor UV credentials may actually cause greater damage to the eyes than not wearing any sunglasses at all.
