Default Costa 580P vs. 580G

Guys, looking to purchase a new pair of Costas, and on the sight, they've done away with blue lenses as an option for 580P. Now, the only option for blue in 580's is Blue Mirror 580G. Wondering if the difference between the 580G and 580P is worth the ~100$ price difference. Anyone have any experience on this subject? I know the sunglass topic has been beat to death, so I'm not trying to beat a dead horse.

Back to the top for this 580P vs 580G question. I'm interested in hearing feedback on these 580 glass vs 580 plastic lenses too...

i have a pair of 580p and 580g. The Glass lenses are a little heavier but they are alomost impossible to scratch during everyday usage. The 580p are lighter, but are also easier to scratch. I take my 580g's in saltwater because i can whipe them off dry with salt on them and they don't scratch. I will only use my 580p's in fresh water.

Dookie,

Can you see any difference in polarization between the 580 glass and the 580 plastic?

One is Polycarbonate (P) and the other is Glass (G). I own both the 580P and 580G..

Pros 580G:
the mirror finish
the G doesnt distort your peripheral vision
leneses doesnt scratch as easy
Cons:
Heavy
lenses tends to delaminate

Pros 580P:
light weight
cheaper
cons:
lenses scrathes easier
your peripheral vision is distorted

I prefer my 580G over my 580P.. the distortion in the P gives me headaches..

Mine are two different colors. I have Brown for fresh water and smoke for salt.

I've never gotten headaches or noticed the distortion from poly but do save the glass for special trips. Chartering daily I tend to use the poly as the workhorse. While they eventually scratch, I've found they drop safer, get thrown around on deck and across the truck dashboard with resilience. I don't purposely abuse them but it sometimes happens, and I am more afraid of the glass breaking.
Poly is much lighter to have on your face all day too and there is still an excellent polarization quality. I have 3 pairs of each g and p and am never disappointed in which ones I grab for the day.

I have both, and my 580P's are de laminating at around a year and a half old. I do wear them everyday though. i liked them being a hair lighter, but they aren't the same as the glass ones. i can see a little better with the glass ones as well, I think the polarization is a little little bit better. I like the blue mirror on both.

I lost my 580G's this weekend. I had them for three years and they were virtually indestructible.

I ordered another pair this afternoon.

Pros and cons to both. I have a pair of P's and I would buy another pair. They are lighter weight, and tough to break. The G's are heavier and can shatter. Just my 2 cents. No matter what you won't go wrong with a pair of Costa's.

Too bad they don't make the 580P in a blue mirror.

I agree totally just got my first pair of G and put them on and was loving them more than any other ( 4th pair of costas) after a week of daily use hung them up for here and there and back to a 4 year old pair of P rincons . To heavy for sure for my taste in every day use.

I like the glass lenses. Despite what is posted here by others, I do not find the glass too heavy, and I love to wipe the salt spray off without any scratching. Plastic is lighter will not break if dropped, and is virtually unbreakable, but I love the blue mirror glass lens. i always wear a retainer strap so I do not have them fly off my head or drop. I wear the 580P lens while hunting and it is a great lens with the same performance as my glass lenses.

Glass lens is slightly heavier at first, but you'll adjust. Also, the fact they wont de-laminate, harder to scratch and improved optics are definitely worth the extra coin.

Glass all the way. I'd take the lesser glass (400) over the better polycarb (580) personally. The glass just gives you far better optics. I've never noticed the glass being too heavy, but I guess that depends on which frame you get and how big the actual lenses are. The polycarb would give you the shatterproof benefit, but also would scratch much easier.

580 g lenses are very scratch resistant. I only clean my glasses with my t shirt. They hold up nice.

I have the Tripletails with both the 580g and 580p lenses. The 580g's are better sunglasses, but the 580p's are much more comfortable to wear all day. The glass lenses of the 580g's are heavy and hurt the bridge of my nose after wearing them more than a few hours.

Default delamination

new at this lol so my question for below are.. like... do all sunglasses delaminate? and whether they do or not, doesn't it depend how u take care of them, or they will anyway overtime? I have 400g bcause my boyfriend won a gift card to the PX and they hapened to have them and I love the blue lens on them(although I prefer white frames lol) he hoped I'd keep them to save $ lol but I couldn't help get 580 from Amazon with white frames which was eh $90 more than the ones he got me I'm undecided which to keep or if I even want either one... it's a lot of $ for something that may not last... I'm also deaf so I had cochlear implants done and the right side hurts more with some sunglasses such as wayfarer style so that's why I wasn't Gona go back to wayfarer even though they're normaly cheaper...
