580P and 580G are two polarized sunglasses by Costa, formerly known as Costa Del Mar. These glasses were invented to protect eyes from full and harsh sunlight conditions.
People who spend a lot of time near shore or fishing on the salty water during the day suffer from the glaring sunlit. These harsh glares cause eye strain and sight distortion after a while. Seeking the solution a fisherman invented these protective polarized film glasses.
Polarized glasses are a good choice for people who spend time outdoors. In the bright light condition, you may lose visibility with the high-glares. And the UV rays distort the color accuracy of your eyesight. Polarized lenses are the only solution you have. The 580P and 580 are two well-known polarized sunglasses by Costa.
The lenses are made with a polarized film inside of the build material. This allows fewer UV rays in your eyes when working in bright light conditions. And give you a clearer vision.
This increases contrast to show you a vivid and color-enriched view. The color distortion is minimal with a polarized sunglass.
The lenses reduce glares and reflection. This way you are out of sudden flashing that causes long-term sight distortion.
What is Costa 580P?
580P is Costa’s premium lineup of sunglasses. Here the “P” is for Polycarbonate, meaning that the lenses are made out of Polycarbonate material in these 580P glasses.
The lens of these 580P polarized glasses is made of 6 layer material. In addition, there is a C-WALL Molecular Bond on the top of the lens, which protects the inner lens material from water and dust molecules.
Then the optional mirror is underneath the protective layer. In the third row, one of the two polycarbonate lenses is installed. Right after that the polarized film that’ll keep your eyes from high glares and color distortion.
After that, the second polycarbonate lens and finally the C-WALL Molecular Bond is found.
What is Costa 580G?
Another Costa polarized sunglass model features better visual clarity and toughness with the build quality. The 580G lens is made out of glass material. The “G” with the model number 580 means Glass.
580G also features 6-layer construction. Like the 580P there are two C-WALL Molecular Bond; one is on the top front of the Glass and the other is on another pole.
After the molecular bond layer, there are glass layers. The glass layers are in both sides of the lens and they are in the next raw after the molecular bond. These glass layers make the sunglasses toughened and offer clear vision.
Next to the glass layer, from the top, the encapsulated mirror, and amid the layers, the polarized film is found. The mirror and the polarized film create great contrast and color and allow less glare insight.
580P VS 580G
Both the glasses are identical with their looks. Yet they have some differences. The minor but noteworthy differences are mentioned below to give a crystal clear idea about these two polarized sunglasses.
The lens is built with Polycarbonate
The glass-built lens with Costa’s LightWave Technology
Lighter than Costa 580G polarized glasses
Has a bit of extra weight because of the glass material
Toughened but fragile on strong impact
Polycarbonate tends to get scratched more easily
Scratch-resistant and provides better clarity
So, the major difference is the lens build material. Where the 580P lenses are made of polycarbonate/plastic material the 580G lenses are built with superior glass sheets. Though both have pros and cons. But the Glass is more scratch-resistant, and toughened construction should hold it even in a good impact.
Talking about the weight, the 580P is the clear winner here. Since the build material is Polycarbonate which is lighter than Glass, the 580P is feathery.
Polycarbonate ends to get faster than Glass. 580G uses Glass as lens material. As a result, the glasses are more scratch-resistant and they give you clear visibility. Color and sight distortion are minor with the glass lens.
The 580G lenses are 22% lighter and 20% thinner than the average polarized glasses.
Both these glasses are polarized, and they protect your eyes from high glares and brightness. Working for a long time it the bright-light conditions cause your sight distortion. UV light is harmful to your eyesight. Both the glasses protect your eyes from UV rays. To have better and clear vision under direct sunlight whether you are fishing in the middle of the ocean or working by the seashore, pick one of these polarized sunglasses.
There you are!
With the spec and feature differences of these two models of Costa Sunglasses, you can easily choose what is most suitable for you. They both support better than some typical, low-budget sunglasses in the market.
Which one is more comfortable?
Depend on your personal preference. If you like a lightweight polarized sunglass then Costa 580P is the choice. And if you don’t have the weight issue, then go for the 580G since this provides better clarity.
Can I dive with these glasses?
The 580P is polycarbonate-built. So, the lightweight and scratch-resistant technology should allow you to go for a dive. The 580G shouldn’t make any difference.
Are they durable enough?
Both of the sunglasses are made with 6 layer materials. The lenses are strengthened and made for better impact resistance. Both of them are coated with scratch-resistant C-WALL Molecular Bond.
How comfortable are these glasses?
580P and 580G both sunglasses are comfortable for the eyes. The plastic-built lenses are too lightweight yet effective and durable. And the glass material built 580G is thinner and lighter in weight than other conventional glass lenses.
How effective is the polarization on these lenses?
The polarization in both the 580P and 580G is better in quality than many other polarized glasses. In both lenses, the polarized film is in the middle of the layers. This resists the UV rays from reaching your eyes. The polarized film makes the light parameter contrast and clears the visibility by not accepting the extra glares inside.
