I have the same optical swimming goggles already tinted in dark brown from the same manufacturer and am very happy with it, it made me perfectly protected even at two summer beach holidays (and not short-sighted stumbles through the area but can really look sharp ... :-) ) Now I was looking for a swimming goggles for indoor use in the swimming pool, these glasses are the best techniques. Did they - more random - tried, without me being abgeschminkt this, and I had no waterproof makeup. A welcome side effect: The glasses appear to sit as close to the eye that really no water, I was able to take off the glasses for about 30 minutes swimming and was just as perfectly made as before. From my five star !!!!!!!!
