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 LOVE LOVE THESE GLASSES I got the Isabela retro tortoise glasses with polarized plastic grey lenses for my birthday and I cannot tell you how much of a life changer Costa glasses are! They enhance colors and simply make life better. I have blue eyes and with regular glasses I still have to squint but with these I do not for which I am grateful. These are also very helpful when it comes to fishing, I can see the bass underwater following my lure so I know just how fast or slow to move it. Thank you Costa for amazing glasses!

Rated 5 out of 5 by from I absolutely love my glasses, shipping was super fast! Quality is great so far. I bought one pair that didn't fit and the return process was simple and refund fast so I could order a different pair. The only thing I would suggest is to include all the little items like cleansing cloth/paper work etc.. In each package. The two shipments had different packing inside. This won't stop me from ordering more, I love the glasses and worth the purchase!

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).
