yea I used to get it bad from surfing, fishing, boating, kayaking, waterskiing......anything in/near the water. I did some reading and some advice from my dad and bro, I went out and got some good sunglasses for the shore. Costa Del Mar makes some great glasses, they are expensive, but if you keep up with them they are great.
the affects of UV light to the eyes is bad. cataracts and retina damage only top it off. dark glasses will make your eyes feel better at the time, but that night they are still gonna burn, and your head is still gonna hurt. what you need to be going for is polarization. it takes off the glare, which is a life saver.
I've got some old, but very nice Aviators that my cousin used, and didn't need them anymore, so passed them on to me. they got the hooks around the ears, so it would take a mavericks wave or teahpoo to knock them off. I really dont care how they look, they are worth it.
I really dont wanna put up with the crap that some people do for not keeping up with their senses. its not worth losing your sight over 100-200 bucks of a nice set of glasses, which will last you a good 10 years if you keep up with them. most have lenses that are virturally scratch proof, except with like a diamond, only problem that those are usually glass, which fogs alot, especially for me, because I don't tolerate hot temperatures well, and where I live is the humidity capital of the world.
its worth it. wear glasses, dont look while people are welding, and wear ear plugs whenever there is anything loud at all.
