Rubber on Costas

They'll replace those no problem. They acknowledge that pairs they made 5+yrs ago have an issue with the rubber parts interacting with Sunscreen, that's why most of the newer ones had the rubber strips minimized or redesigned.

I had the same problem with the old style corbinas with the rubber around the whole frame. When it came undone they sent me the new redesigned pair with much less rubber. I’ve found that the rubber that is there has performed much better so not sure if they updated the glue or rubber compound.

On my third pair of tuna alleys bc of the rubber nose pieces coming off. I file a claim every two years and they replace at no charge. Some may think it’s a pain but I have an extraordinary amount of patience when it comes to deals and warranty work.

They honor it. There is a chance you won't get the same frames again though. I sent two pairs off this year. One came back the same the other was a discontinued frame so they gave me options on a different pair. I ended up with two brand new sets of glasses and zero charge.

As for glue the best I have used was arrow fletching glue. Saunders or fletch tite platinum.

I was told that the oil chemistry in some people's skin is cause. I have friends that never have this issue with their Costa's so who knows. It happens to me every couple years. I don't wear sunscreen either so I know it is not that.

They will cry foul on the cracked lens; but may offer you new lens at a reduced cost (still high as giraffe nuts). They should address the rubber as normal warranty and either repair or replace the frame.

Sending mine back this week for the nose piece, super easy process.
