I bought these goggles for a practice of yachting on the beaches. UV sun protection side, nothing to say. No fogging and effective protection against water splashes and sand ... The only downside is that it is difficult to remove the sand, rolling without scratching the surface of the "glass": anti reflection scratched instantly! So pay attention, in this application or in the case of abrasive projections, it is imperative to rinse the glasses under water and get rid of any adhesion and wiping them. Is therefore intended for careful people who accept the side or "consumable" product. The low price would opt to do so.
