Where can I order such eye wears?

[eyeglass frames]

This is my forth time to buy eyeglasses in the past half years! I cannot leave all the responsibility to the quality of my eye wears, as I work at a tough circumstance, I am a fisherman actually, I live on a boat and the salt attacks frames and corrodes them very quickly and when I sit on them or find I've dumped a tool bag or other piece of kit on top of them. So, I'm looking for bendable, unbreakable, corrosion-resistant frames. And what kind of coating is the most helpful for a fisherman, as in my experience salt seems to attack coatings as well?
