A post similar to this came up sometime last year. I had recently crashed so hard that I broke my last pair of Surf Shades and was looking to replace them. I wanted something with better lenses and decided to give the Lip Typhoons a shot. Long story short, I liked them so much that I contacted them and became a dealer for them. Not only did I like them, I sold everything I got and everyone has raved about them. In my opinion, the Zeiss lenses on the Typhoon model are worth the extra $100. When you put them on next to pretty much anything else, you can really see the difference in clarity, sharpness. The hydrophobic/oleophobic coatings have been really nice. I have to clean these SO much less than anything else I've had, even considering how much abuse they get from me as an instructor. I'm getting a second pair for my house, since I live 1/2 hour away from where I work, and I can kite close to my house.
Now, if you're one of those people that is perfectly satisfied with the $5 safety goggles from Harbor Freight, well, these are NOT the glasses for you. If you wore them, you'd be able to tell the difference in quality instantly. But, the extra $200 you spent will likely bug the crap out of you and ruin the purchase.
However, if you're like I am and appreciate quality in sunglasses, I can't recommend them enough.
As a side note, my father has spent most of his adult life owning his own residential construction business and working outside. Due to heredity, environment, or a mix of both, he's been battling macular degeneration for about 10 years. That's certainly made me more vigilant about taking care of my eyes, especially with how much time I sometimes spend outside. Just one more reason why I have no problem spending a little extra on them. Hope this helps.
