Costa Del Mar Tuna Alley Review

Costa Del Mar Tuna Alley Sunglasses Review (On-Water Testing)

Continuing on with my quest to find the best sunglasses for fishing. I’ve got the Costa Del Mar Tuna Alley’s. So, I decided to give the Costa Del Mar Tuna Alley fishing sunglasses a try, and let me tell you, it’s been quite the experience.

Tuna Alley On Water Results

The Tuna Alleys’ were impressive on the water.  The day I tested was full sun and I attempted to orient the sunglasses to catch as much glare as possible.  A perfect test for these darker shades.

Overall Rating Compared to Other Fishing Sunglasses

The Tuna Alley’s just made the top 10. I tested over 17 sunglasses in total, the manufacturing concerns and getting a scratch after 4 days of ownership really put a dampener or some sunglasses I thought would finish near the top. A hot tip — check out the Costa Fantails. Around the same price and they finished near the top of my results and I highly recommend them especially if you’re fishing in harsh sun saltwater conditions

I enjoyed the style of these sunglasses and found the wrap to fit me fairly well.  Remember I have a bigger head (large hat size) When trialed on my daughter they were a little on the large size.  (she wears a small hat)

Impressive Polarization and UV Protection

The first thing I noticed about these sunglasses was the impressive polarization. I could see the difference as soon as I put them on. They cut through glare like a hot knife through butter, allowing me to spot those sneaky fish hiding beneath the surface. I was also pleased to learn that they offer top-notch UV protection, which is a godsend for someone who spends hours outdoors trying to reel in the catch of the day.

Noteworthy Items

I purchased the 580G (glass lens) but the sunglasses sent were the 580P (plastic version).  This was disappointing since the glass lenses should have better clarity and I am evaluating “the best fishing sunglasses”.

The response I got from Costa Del Mar was that since I bought them from Amazon I would need to work through them.  I wasn’t very happy with this response since the labeling on the glasses was incorrect from the factory.

Tuna Alley Lens Choice and Visibility

Now, let’s talk about the lenses. I wanted the glass lenses but was sent the plastic.  The lenses were a mirror green with a rose/copper tint. It’s a snazzy look, if I do say so myself, and the lenses really helped in enhancing the colors and contrast of my surroundings. With a stated VLT of 10%, these lenses were perfect for those bright, sunny days out on the water.

My VLT Testing

This is highly caveated; my testing is only related to the sunglasses I tested.  The Tuna Alley’s were definitely on the darker side only allowing an average of 14.9% of light to pass through. 

Comfort: Room for Improvement

As much as I appreciate the Tuna Alley’s performance, I must admit that they weren’t the most comfortable sunglasses I’ve ever worn. The lack of a proper nose pad left me feeling a bit sore after a long day of fishing, and I couldn’t help but notice some bumps on the nose area. It wasn’t a deal-breaker, but it’s worth mentioning for those who prioritize comfort.

Durability: Sturdy, but Lacking Spring Hinges

One thing that surprised me was the durability of these sunglasses. The plastic frame material is fairly robust, but I couldn’t help but notice the absence of spring hinges. I’m not one to treat my sunglasses gently, so I do worry about their long-term durability.

Scratch Resistance

The Tuna Ally lenses have “C-Wall” r technology for scratch resistance.   I can’t give a plastic lens as high of scratch resistance as compared to a glass lens.   My sunglasses scratched after 4 days of gentle handling….

Price and Value

As for the price, I paid $223 for my Tuna Alley sunglasses. While they’re not the cheapest option out there, I found the performance and quality to be worth the investment. Plus, with a 4.7-star rating at the time of my purchase, it seems like other users agree.

Wrap Curvature: Excellent Coverage

The wrap curvature of these sunglasses is base-8, which provided excellent coverage and peripheral vision while I was out on the water. It’s a feature that I’ve come to appreciate, especially on windy days when I need that extra protection.


I struggled to find the warranty information on the Costa Del Mar website.  The written material that came with the sunglasses stated – “to read more about the warranty go to the website”?

I’m going to assume they have a 30-day warranty because I purchased them from Amazon. 

Pros and Cons


  • Impressive polarization for excellent glare reduction
