Their versatility will leave you agape. You can have them while fly fishing and on your casual walk up the mountains. These Costas make you draw admiring looks and no harm comes your way when you wear these protective sunglasses.
Since 1983, nothing Costa Del Mar hasn’t produced anything substandard. The company goes further to classify their sunglasses depending on lifestyle collections – the Angler, Beachcomber, and Voyager. All Costas feature some of the best technologies. They all put performance and functionality above style.
The company brags of being the first manufacturer to have and start using an all-polarized technology that enhances color. This is the 580 Technology that has almost 100% polarizing efficiency. They effectively block out bad HEV blue light from reaching your eyes. A 580 lens will filter extremely bright yellow light and make the greens, blues, and reds pop out resulting in sharper images.
The stylish wraparound frames are durable and block the sun from reaching your eyes through the sides. This prevents distortion of vision. It doesn’t matter if you are fishing, taking a rest on the beach, these glasses stay secure when water drips down your face.
Costa Blackfin sunglasses have non-slip materials that ensure the glasses stay put as you fight to reel in a big one. Bio-resin frames are high-quality and add to the lightness of the sunglasses. This attribute is excellent especially if you are staying out in them for long hours. You know how bad a headache because of heavy glasses is.
Costa Del Mar makes the Blackfin in two different types of lenses; glass and plastic. Both materials offer positives. Most importantly, it will depend on what you intend to use them for. If you are going fishing, you can choose either of the two. To know the glass models in Costas, there is a G along the product’s code. While plastic lenses are good, glass lenses have better clarity and have a yellow light glare. It has good scratch resistance. Plastic is light and comfortable for wearing all day.
Lens technologies in the Blackfin come in two options. The 580 and 400. 400 offers 100% UV blockage and polarization like the 580 and provides superior clarity. Let us head to sampling the sunglasses by assessing the main features, the upsides, downsides, what users are saying about this masterpiece and clarification on most asked questions.
Main Features of the Blackfin Sunglasses
Lens Material – Blackfin by Costa are made from either plastic or glass. Plastic lenses are lightweight and have high impact resistance. Glass, on the other hand, has superb quality and scratch-resistance. However, they need more care because they easily break. Both plastic and glass have a 6-layer lens construction for high performance and durability.
Lens Color – Costa Del Mar Blackfin Sunglasses come in any lens color that you might need for outdoor activities. This review is for the Blue Mirror lens color. A different color gives a different result depending on the environment you are in. Blue Mirror gives superior contrast and eliminates glare in open water. The Green Mirror enhances visual acuity and is good for flats, rivers and inshore fishing. Copper cuts glare while enhancing contrast and is good for daily activities. Sunrise is a high contrast lens and is great for night fishing. Gray maintains natural contrast and color saturation and is an all-round lens. Amber a brighter field vision and is good for all activities that need high contrast.
Nose and Temple Pads – The endurance line is made from Hydrolite at the temples and nose bridge area. It is a soft rubber that allows the sunglasses to stay put despite your face being wet with sweat or water. They are essential especially when raising your heart rate and going after a catch.
Hinges – Costa hinges are corrosion-resistant and very flexible. They keep their shape at all times and ensure the sunglasses fit perfectly fit. Blackfin sunglasses can be used in saline environments because of the anti-rust properties of stainless steel hinges.
Polarization – All lenses are polarized regardless of the technology and lens color. 100% polarization is recommended when fly fishing and this is what Costa Del Mar Blackfin offers. The lenses block all glare created by the sun’s reflection on water, sand or snow. This protects you from impaired vision and discomfort. Eyestrain reduces your focus and you might not spend longer on water.
UV blockage – It is crucial to protect yourself from the harsh UV rays that can cause cataracts. You need lenses with 100% UV protection like the Blackfin. As you pack your hat and sunscreen tube, don’t forget your sunglasses.

Frame sizing is as follows: Lens Height-39.5mm, Lens Width-62mm, Distance Between Lenses-18mm, Temple to Temple-129mm, and Temple Length-115mm.
