Rated 5 out of 5 by from Amazing Sunglasses!! I bought these about a month ago after having cataract surgery in both eyes and needing good eye protection. I must say, I was skeptical about the blue lenses but, I absolutely Love them!!

Rated 5 out of 5 by from Love my new sunglasses Bought these sunglasses after the nose pieces fell of my previous Costa Del Mar Isabela sunglasses. I needed to have new lenses put in the old ones along with the nose pieces and after I priced the repairs, I realized it was almost as cheap to buy new sunglasses. My new pair has a lighter lens which I LOVE! The colors are so crisp and clean even on overcast days. So glad that I purchased the new pair!

Rated 5 out of 5 by from My wife had a pair of Isabellas before and unfortunatley they were either lost or stolen. After trying many different brands and styles,she commented that NOTHING compared to her Costa sunglasses. These were a surprise last minute Christmas gift and they made her Christmas complete. She loves them because they are very stylish and she can use them when she plays poker.....Double win !!!!!!

Rated 1 out of 5 by from Isabela I bought the Isabela model for my wife. After the first week, one of the lentels loosened and would not stay tight. I've owned 5 pairs of Costa sunglasses and this was disappointing. However, this is not typical and Costa made the return easy. I just hate that I now how to pay the extra shipping to get what I originally ordered (a pair of Isabela sunglasses that were not defective).

Rated 5 out of 5 by from Great sunglasses I bought these as a gift for my girlfriend to replace the ones she has had for 4 years that are no longer sold but she lost them after having them a week. I guess she will be using the old ones until I can save up to buy her another pair of these. I wish she would have lost the old ones but she loved the new ones for the short time she had them

Rated 1 out of 5 by from Lens Scratch Easily I bought a pair of Isabela Costa sunglasses in March. I used the provided lens cloth to clean the glasses religiously but they still got all scratched up in just a couple of months. I owned Serengeti brand glasses before and they seemed to be more durable. I have not yet contacted Costa Warranty department.
