    • Costas for a great price.
I was skeptical, but I broke a lense about two weeks into owning these. Definitely glass, and sent them back to costa and they repaired them, so definitely costa

    • PERFECT for fishing, even better for daily wear
Perhaps my favorite pair of sunglasses I have ever put over my eyes. Second to this pair are the 580P Tuna Alley by Costa. The glass lenses are VITAL to everyday use. They are incredibly scratch resistant and one can even take car keys directly to the lenses and intentionally try to mark on them and no scratches shall amount. The green mirror bronze based lenses are perfect for murky water consistent down here on the Texas Coast. Ponds and lakes are without any glares and the surf at the beaches are just as glareless.I wear these everyday while driving and couldn't imagine a better daily AND fishing pair of sunglasses ... show more

    • Still my favorite brand.
I’ve worn this model Costa for years. It’s one of the widest frames they offer and fits my head well. I didn’t really need another pair, but they were 100$ !!. They have the 580g lenses and retail for 273.00! The company is not the same since Luxotica bought them but I still can’t find anything else I like more. ... show more

    • Fantastic glasses
I love these glasses. Didn't want to spend this much money but got tired of the coating not lasting on the $20 fishing glasses I have been buying. These are holding up very well. They are by far the best sunglasses i have ever owned. Great for fishing as well as working on the farm or on the excavator ... show more

    • Great fit/feel
Glasses arrived as described and in two days! Could wear all day without noticing they were even on. Felt that they did a nice job looking into the lake, but was a clear water lake as well - still waiting to try on a stained lake. I've started to not even take glasses along when I go for a walk as I would get headaches. Forgetting that these were on, I could push the grand babies around in the stroller and went for a walk with no issues. Only a four rating as I've had these for less than a week and really want to try on different bodies of water. ... show more

    • Alright, but pay extra for glass lenses
Color: Tortoise Lens Width: 63.1 Millimeters
First of all, the glasses were a little bit too big for my face. That isn’t why I’m only writing it three stars, but that is just being put out there as a fact. I have six other pair of Costa sunglasses and they all fit perfect. I have glass lenses in all of them but I decided to go with polycarbonate this time, and I was disappointed. The clarity wasn’t near as good, and they scratched up very easily. My vice is to spend the extra money and get the glass lenses. ... show more

    • One of the few high end manufactures that offer quality glass lenses.
I really liked the glass lens just like the high end sunglasses back in the past. Plastic lenses used to be exclusive only to cheap sunglasses. It is hard to justify to buy any $100+ sunglasses if they have plastic lenses regardless of brand.
