I don't surf without them.
Owning and operating a full time surf tour operation, I surf on average between 4 and 8 hours per day, and at 29 years old I have already suffered from multiple bouts of long-term sun blindness and have a pterygium encroaching on my iris. Ever since I started wearing SeaSpecs, however, my eyes have been perfectly fine. My pterygium has stopped growing, and I haven't experienced any sun blindness at all! In addition, I find that SeaSpecs hold up to use much better than other more expensive surf-glasses on the market. SeaSpecs enable me to surf epic waves under the equatorial sun for as long as my body can last. I don't surf without them.
