Summer’s coming in, and it’s jam-packed with UV rays that can pack even more harm on your eyesight.
So what better way to protect it than by donning a great pair of sunglasses!
Costa Del Mar is one of the many popular brands that leads a good cause. As its roots are found at a beach, Costa made sea life its problem when it leads preservation of life in the waters.
It’s able to keep doing this through each purchase you’ll make on their store, so you’ll be lending a hand on its cause as well!
Other than helping along, of course, you’ll want to know whether what Costa is selling is legit or not.
So, which one is better between Costa 580g and 400g? Let’s find out! And that’s what you’re here to find out!
Costa 580g
When you hear about Costa’s new face of lens technology, the 580g is your guy!
This premier lens took polarized lenses on another level to absorb high-energy blue light on top of the usual UV rays.
“What’s so bad with this blue light?” you might ask.
Well, high-energy blue light (or HEV light) is, to put it briefly, WAY more dangerous than the UV rays.
Other than being the root of many, many skin problems through continued exposure to it, HEV light also has a knack for penetrating the eye deeper than UV, which could cause macular degeneration, pterygium, cataracts, and an onslaught of more to come.
So, HEV light is bad news right there, but the 580g lens absorbs it, no problem!
And if you’re new to Costa, you should know that it already has an integrated 100% protection from UV light. That’s double the protection against any light that wants to mess up your retinas!
Also, the lens absorbing the HEV light comes with the package of cutting through haze and blur, so you have far greater clarity compared to other cheap shades out there.
Besides that, the 580g made it its job to block out the yellow light (smack-dab at 580 nm on the visible light spectrum!) that could be too harsh for your eyes.
Instead, it enhances the colors and contrasts from reds, greens, and blues to give everything a higher definition.
However, with how much is packed in these glass lenses, you should be prepared by its slight weight, so it might slide down your nose a lot, mainly if you chose the wrong size.
Costa 400g
Before anything else, visualize this first: a sleek, pure black stallion beside a Ferrari race car.
Both of them have the same purpose (quick transportation), but there are drawbacks to both of them, with one of them even more obvious than the other.
That’s how it goes with the Costa 400g.
At some point in history, everyone’s going nuts over the biggest, strongest horse there is. Now, that’s pretty much the same but with cars.
The 400g guarantees complete protection from any harmful UV rays as it’s still under Costa.
Although it’s glass like the one from 580g, its lenses are durable and scratch-resistant, so it’ll be perfect for a surfing sesh or a peaceful boat ride for a fish.
Also, as Costa has a wide array of tints available, the 400g goes along well with either blue or green mirrors, two of the most common mirror lenses there are!
Of course, as this is already an out-of-date tech, these features are the only things going for it.
On the bright side, it does make it lighter than the 580g, so that’s something.
But it does come back down once you hear that the 400g should be discontinued at this point since the 580g is Costa’s new premier lens.
Features of Costa 580g and 400g : Similarities & Differences
Made Out of the Same Tree
Or the same “glass,” to be precise.
It’s only mentioned earlier, but both are made out of glass called the LightWave glass.
Hence, the “g” beside the number.
You’re probably worried over how this might fare after dropping it by accident, but no need to worry!
Costa Del Mar’s goal is to deliver a quality experience wearing its products, and you can’t have that if it falls apart after an accident, right?
Durability is a must in both lenses and frames from Costa, paired with clarity so you can enjoy the view despite the sand and grit picked up by the wind.
As these lenses are scratch-resistant, you can pose as much as you want on the beachside without thinking of any sand getting in your eyes!
Layer upon Layer
Packed tight in the 580g lens is the many patented technology from Costa.
The outermost layer has the C-Wall molecular bond that both 580g and 400g have as it provides a barrier from scratches or smudges, even repelling any fluids like oil, water, and sweat to make it easier clean.
But it goes even further for the 580g.
Underneath its C-Wall is a glass layer since it enhances the clarity in everything you see.
Following it is the encapsulated mirror that backs up the C-Wall’s scratch resistance by backing it up with its scratch-proof feature.
Then, it has the polarized film to protect you from UV rays entirely, followed by another layer of LightWave glass and, last but not least, the C-Wall.
It’s safe to say that the 580g has it all regarding protection and clarity.
Out with the Old, In with the New
As mentioned earlier, 580g is the new face for Costa’s lens technology, and with good reason!
You can see how it has layers upon layers of protection for you to enjoy while under the sun. It even safeguards you from HEV light, which is guaranteed to be so harmful it makes the UV rays look like a baby sunburn.
Which, newsflash, it’s not!
Just because the UV rays seem to be just an inconvenience compared to the HEV light, that doesn’t change the fact that there are so many causes that can affect your eyesight just by standing around under the sun.
Through the wonders of technology, Costa patented the 580g lens to double down these causes and have you frolicking on the sea or the beach with one less problem since your eyes are taken care of.
Of course, since this is a somewhat new technology, you might have to make sure what you’ll be buying from a retail store is legit.
One thing to look out for is its mark.
Authentic 580g lenses have a small 580 etched onto the corner of the lens, even the prescription ones!
As it’s much older and (probably) discontinued, the 400g doesn’t have any of these etchings on their lenses to make them distinct.
So you better keep your eyes peeled when you get around to checking Costa out!
Final Thoughts
In technology, each tomorrow is another step in advancement, which happened between the Costa 580g and the 400g.
Sure, the 400g might have been a big hit way back, but Costa found this as an opportunity to better its tech to be something more, and a 580g lens is the outcome of that.
Of course, there’s no doubt that Costa would take it up a notch sometime in the future until the 580g turns out just like the 400g.
But for now, the 580g is already a great feat in lens technology, and Costa wants you to experience this once you get your authentic Costa Del Mar sunglasses.
