IKON LENSESReplacement Lenses For Costa Bloke Sunglasses (Polarized)

Was getting tired of my original lenses that were all scratched up. Great fit to the frame, incredible color and a durable product.

Perfect fit

Delivered a few days late. However when they arrived they look good and snapped right in replacing my old scratched lenses.

Muy buenos, buen polarizado…

Fit perfectly. Not as heavy as originals but a great, cheap replacement

I accidentally ordered the wrong lens. But they quickly sent the correct lens for my Saltbreaks. The lenses were simple to install and even came with a micro fiber rag and cleaning solution.The saltbreak fire lens is great being Costa doesn't offer this color. I will be buying these ikon lenses in the future and would definitely recommend you do the same.

Excelente compra

I ordered ICE BLUE, Green Mirror, and Violet Mirror. I am keeping the Ice Blue and returning the others, here's why...1st, these aren't high quality lenses. 2nd, these are replacement lenses. 3rd, expect to get what you pay for.Most disappointment surrounds the coating on the outside of these lenses. Most quality lenses which have a mirror finish use the mirror to help identify which color the lenses actually are. These lenses are not that at all, and instead it seems each lens is a light brown. In other words, if I compared these three colors in Oakley or Costa brands lenses, each lens would look different as you view through them, as different color lenses are better for certain activities and highlight or mute certain spectrums. These finishes are just aesthetic, not functional.These lenses fit the frames great, feel sturdy and were mostly free from defect. The Green Mirror lenses have some film inconsistencies in the corners of the left and right lenses which are obvious when looking through the front or the rear of the lens. I assume all manufacturing has occasional hiccups like this, but it would have been nice if quality control had noticed and weeded these out as I preferred this color to the others but didn't want to return these and wait for replacement.The light transmission stats provided for these lenses are not even close to being accurate and IKON should consider reevaluating their claims. The Ice Blue claims a 10% transmission, but when held up to my Oakley's which are Dark Iridium @ 12%, the Oakley's let about 1/2 as much light in, they are very dark, the darkest I believe you can buy. I need this due to an eye injury and driving when the sun is low in the sky is impossible without something of this darkness....so I was hoping the claims from IKON were accurate. The Violet and Green Mirror lenses are rated at 12% and also not remotely close to the darkness of the Oakleys.As for polarization, these lenses claim polarization and they are, to an extent, polarized. I bought these replacements because my dog scratched my original 580p green mirror from Costa, so for polarization comparisons I used these lenses. It happened to rain outside the day these arrived so I was able to use puddles in the street and my neighbors kiddie pool to test. While the IKON Lenses are polarized, I would say they reduced the glare/refraction by 30% or less than that of the Costas. Just to try another lens, I tested against my Oakleys and the IKONs only reduced about 20% as much.All-in-all, for $35 bucks I'd say I am happy with the lenses but I will not be wearing them for activities such as driving, golf, boating or fishing. They certainly underperform in these areas of high need. Instead I will take them hiking, cutting the lawn or other outdoor work where my eyes need reduced brightness and there is less light reflection to deal with.
