TREVALLY is rated 4.6 out of 5 by 48.
Rated 5 out of 5 by from Amazing lenses Loving my new Costa glasses. The 580G amber lenses show the world in super high definition, and work like x-ray vision through the water. The glass lenses have not had an issue with multiple weekends subjected to salt water, and seem to be resistant to any scratches so far. The size of the Trevally are just right for my face, which runs a little narrow for most sunglasses. I was able to find a pair in a store to try, but not the combination I really wanted, so had to order online. Costa should start a dedicated store with all the numerous options available to try and buy, they would sell a ton more glasses, most retailers have a very small selection to try in person.

Rated 5 out of 5 by from Perfect for small faces Thank you Costa! I am a forever customer and will recommend you to everyone. I chose these as a replacement for my Daphne's and they fit perfect. I am petite and have a hard time finding glasses that don't overwhelm my face. I couldn't be more pleased.
