Blackfin 580P Polarized Sunglasses


Sweat-Management Design for Increased Airflow

Sunglasses are an important part of keeping your eyes healthy and protected from the sun’s harmful rays. However, when you wear sunglasses for extended periods of time, they can start to fog up from the sweat on your face. This can be a major annoyance, as it can obstruct your vision.

The Costa Del Mar Blackfin sunglasses are designed with a special sweat management system that helps to keep your lenses clear and your vision unobstructed. This system includes special vents in the frame that allow for increased airflow. This helps to prevent the lenses from fogging up, even during extended wear.

The benefits of this system are two-fold. First, it helps to keep your vision clear and unobstructed. This is especially important if you are participating in activities where you need to have clear vision, such as driving or playing sports. Second, it helps to prevent the build-up of sweat on your lenses, which can lead to lens damage over time.

Lightweight and Impact-resistant Polycarbonate Lenses

Polycarbonate is a type of plastic that is commonly used in eyeglass lenses. It is used in bulletproof glass, CDs and DVDs. Polycarbonate is lightweight and shatter-resistant, making it an ideal material for sunglasses lenses.

Polycarbonate lenses are impact-resistant, making them ideal for sports and activities where there is a risk of flying debris or objects. They are lightweight and scratch-resistant, making them a good choice for everyday wear. However, polycarbonate lenses are not as clear as other lens materials such as glass or mineral crystal.

Plastic lenses are made from a variety of materials, including polycarbonate. However, plastic lenses are not necessarily shatter-resistant or impact-resistant like polycarbonate lenses. Plastic lenses can be made from different materials depending on the desired optical properties.

True 580 Technology Increases Red and Green Light

True 580 Technology is a lens technology used in Costa Del Mar sunglasses that allows for an increased amount of red and green light to enter the eye. This technology blocks out the harmful shortwave high-energy blue light.

True 580 Technology works by filtering out the yellow light that can dilute color value. This allows for more vibrant and clear colors. Additionally, True 580 Technology blocks out the harmful shortwave high-energy blue light, which can cause eye fatigue.

The benefits of True 580 Technology include improved vision clarity and protection from the harmful effects of blue light exposure. This technology enhances color vibrancy, making objects appear more clear and vibrant.

Secure Comfortable Fit with Hydrolite Temple Grips

A good fit is important for sunglasses because it helps them stay in place, even during activities. This is especially important for sports sunglasses. A snug, but comfortable fit, is key to keeping the glasses from bouncing or sliding off your face during movement.

Hydrolite is a material used in the construction of some Costa Del Mar sunglasses. It is a soft, pliable rubber that helps to grip the skin and keep the glasses in place.

The hydrolite material used on Costa Del Mar sunglasses’ temple grips works by gripping the skin lightly. This helps to keep the glasses from slipping or moving around on your face, even during activities.

The benefits of hydrolite temple grips are that they help keep your glasses in place and they are comfortable to wear. The hydrolite material is less likely to cause irritation than some other materials used in sunglass construction.

100% Polarization & Protection with Minimal Glare

Glare is caused by the reflection of light off of a surface. When light reflects off of a surface, it is scattered in all directions. This can cause problems when you are trying to see something that is in the path of the reflected light. Glare can cause your eyes to water and make it difficult to see.

The short term effects of glare are difficulty seeing, eyestrain, and headaches. The long term effects of glare are unknown, but it is believed that they could include permanent eye damage.

Polarized sunglasses reduce glare by blocking reflected light. This allows you to see more clearly and reduces the strain on your eyes. Wearing polarized sunglasses can help to protect your eyes from long-term damage caused by exposure to UV rays.

The Costa Blackfin sunglasses are designed with polarized lenses that block out 100% of harmful UV rays. These lenses reduce glare by filtering out reflected light. The wrap-around design of the frame helps to further reduce exposure to UV rays and glare.

Durable and Comfortable Co-Molded Frame

Co-molded frame is a type of frame technology used in sunglasses that combines two different materials to create a stronger and more durable frame. The Costa Del Mar Blackfin sunglasses use a nylon frame with a bio-resin lens material, which makes them both lightweight and durable.

The two different materials are fused together using heat and pressure to create a strong bond. This type of frame is often used in sports sunglasses because it can withstand more wear and tear than a traditional single material frame.

The benefits of co-molded frames are that they are lightweight, comfortable, and durable. This makes them perfect for activities such as boating, fishing, and kayaking where you need a sunglass that will stay put and not weigh you down.

Durable and stylish TR-90 Nylon Frames

TR-90 Nylon is a thermoplastic polyamide that is known for its high strength and durability. This material is often used in the manufacturing of sports equipment and eyewear frames due to its resistance to impact and moisture.

TR-90 Nylon frames are extremely lightweight yet durable, making them ideal for sports and active lifestyles. The material is hypoallergenic and non-irritating, making it a good choice for those with sensitive skin. In addition, TR-90 Nylon frames can be easily adjusted to ensure a comfortable fit.
