Ray-Ban RB2140 Original Wayfarer Sunglasses

The first time I ordered these I was confused about the numbers and sizing of the glasses, and got it wrong. Here's how it works:

The glasses come with either a 50mm or 54mm lens diameter. I can't say whether they're just wider or are also taller, as I haven't tried both sizes.

They also come with a choice between two different distances between the lenses: 18mm & 22mm. I guess if your head is large, you'll probably want the 22mm option.

Model Number Explanation, as far as I can figure. Haven't quite got it down, but this should be close:
The set I own now: 902/57-5022
The first set of numbers is the color/style, ie: Tortoise frame = 902. The number after the slash seems to correlate with lens type, ie: Crystal Brown Polarized = 57. Therefore, 902/57 style is a Tortoise frame with Crystal Brown Polarized lens.
The second set of numbers is a little easier. The first two numbers are the lens diameter and the last two is the distance between the lenses, ie: 5022 = 50mm lens with 22mm between the lenses.

FYI: This style, 2140, is the "Original Wayfarer" style. Others include the 2132 (New Wayfarer), 2151 (Square Wayfarer), 2143 (Wayfarer II), 4105 (Folding Wayfarer), and the 9035 (Junior Wayfarer for kids).

I hope this helps!

The glasses do fog up easily, at least on my face. I believe it's because they are closer to my face than regular sunglasses. For that, and the lack of easy explanation of the styles and sizes, I subtracted a star, but I love the way these glasses look and wouldn't part with them for anything!

<edit> The New Wayfarers (2132) differ in that the lens is more shallow, so if your cheeks hit the classic Wayfarers, they probably won't with the new style. Also, the New Wayfarers have slightly thinner & lighter plastic frames. I prefer the New Wayfarers myself, but they don't make the frame/lens combination I like (Tortoise/Brown Polarized) in that model.

<edit 2> See Amazon Blonde's comments below for a correction and clarification to the explanation above.

Also, if you like the style, but not the way the Ray Bans are constructed, Maui Jim makes a more subdued, but better-made frame with the model number MJ242, sold at Sunglass Hut. They fit me better and have spring-loaded bows, which is nice. Also, they have rubber built-in to the nose, but invisible. They also don't hit my eyelashes like the Ray Bans do.

Without a doubt, the 2140 Original Wayfarers are the coolest and most comfortable sunglasses around. I ordered them with the regular tint, instead of the Polarized lenses because my previous sunglasses with Polarized lenses made it very difficult to read LCD screens. No such problem with the regular lenses and glare never seems to be a problem either.

The only recommendation I'd make regarding purchase is to check your head size to make sure you get the right fit. I've always thought my head was pretty big, but when the original pair of Wayfarers arrived, I found that the 54mm size was entirely too big for my face. I contacted the vendor, EZContacts, and they let me exchange the sunglasses, quickly and without delay, for the 50mm size, which fit perfectly and look great. I never thought 4 measly millimeters would make that big of a difference, but when it comes to the way sunglasses look on your face, it sure does.

So, unless you have a Shrek-size head, my suggestion is to opt for the 50mm size. Oh, and when it comes to cost, I saved at least $40 buying through Amzamon versus the retail cost at my local mall's Sunglass Hut.

To be honest I was quite skeptical but now that I have the glasses in my hands (received in 5 days standard) I'm truly impressed, I received a legit pair of 2140's (hope to turn into prescription sunglasses), did my research & everything checks out, weight & high quality plastic, slant, spear things in front are proper, Ray Ban logo on lense (doesn't scratch off), RB etching inside left lense, 7 prongs (hinges) on each arm, metal bar in each arm, RB logo on the arms are proper, model info correct inside left arm Wayfarer (keywords) Hand Made In Italy on right, case is legit as is the RB box it came in (dead give away for fakes is a recycling logo on side of box), no typos and info on RB box is correct, another thing to note is that when you were them they look a bit crooked but that's normal Ray Ban right there, ordered from vendor Sunglass Express and I've added pics to help those unsure, mileage may vary cause im pretty sure fakes are in circulation, other than that 4 stars, do your research (youtube is good) before buying and good luck, hope this helps.
