question about fittings on glasses (47mm and 50mm)

what is the difference for 47mm and 50mm, how will i be able to find my size, someone please elaborate. (specifically for ray-bans)

Eyeglasses with 47 mm lenses will fit a smaller head. 50 mm lenses tend to fit small / medium face. You will also need to take Ray-Ban eyeglassesnose bridge measurement into consideration. Please let me know if you have any Ray Ban frame model in mind, and I will be able to tell you how big the frame is.

I had the RX5121 in mind, whats the difference between RX5121 and RB5121? and i wouldn't say my face is small, if anything its closer to medium-big

is there a specific size for the nose bridge? they dont have sizings for that do they?

o ya by the way, what is the difference between the ray wayfarer 2 compared to the RX5121 (or the RB5121), frame wise, i am NOT talking about the tinted lens, despite the lens are different, what is different about the frame?

Both RX5121 and RB2151 are Ray Ban Wayfarer style frames. Ray Ban has a few more similar models. All of them allow Rx lenses. Even if you like a sunglass frame more, we can fit it with clear prescription lenses.

RX 5121 is a classic Wayfarer style. It is almost identical to original RB 2140 sunglasses. If you are looking for medium / large sized frame, I would recommend RX 5121 in 50 mm sized lenses. RX 5121 with 47 mm lenses has a small fit.

If the frame tint you are looking for is not available in RX 5121 style, take a look at RB 2140 prescription glasses in the same 50 mm lens size. The choice of Rx lenses is the same for both frames.

RB 2151 that you mentioned comes in a little bit different lens geometry. The lenses are more rectangular in shape than in the original model.

Please let me know if you have any other questions.

is RB5121 and RX5121 the same thing? and what is the difference between ray wayfarer 1 and 2? is the 2 circle glass frame bigger in size for a 50mm compare to a 47mm or is it the same?

would you happen to know what EXACT model this guy is wearin? and if its 47mm or 50mm?

He is wearing Ray Ban RX 5121 frame in 2000 frame color. You will need to choose either 2000-4722 (smaller) or 2000-5022 (bigger) depending on the size. If you think that you need medium / big frame, I would recommend 2000-5022.

Take a look at http://www.opticsplanet.com/ray-ban-eye ... x5121.html

You can also order this model with custom made Rx lenses:

or

http://www.opticsplanet.com/ray-ban-eye ... enses.html - RX 5121 frame with bifocal lenses

In terms of the size, I would say the guy has 47 mm eyeglasses on.

and what exactly is ray wayfarer type glasses? (please answer all questions from my posts since your not on frequently to respond back in time)

how can you tell the difference that he is wearin a 47mm instead of a 50mm? o yeah THANK YOU BY THE WAY FOR HELPING ME! i really appreciate your help

Sorry about not answering all your questions. I will try to respond to all of them now Please let me know if I miss anything again.

how can you tell the difference that he is wearin a 47mm instead of a 50mm?

- his face looks small / medium to me, so I would rather say that he is wearing a smaller frame.

and what exactly is ray wayfarer type glasses?

- Wayfarer is a style of sunglasses that feature rectangular oversize lens design in a trapezoidal frame. This glasses style was first introduced by Ray Ban in 1952. It was shown in many movies and was worn by many celebrities. It is still very popular nowadays. That's why Ray-Ban added some other similar models of the same style. They all slighty differ in size, color and little bit in lens shape. I'm currently working on a small article about Ray-Ban Wayfarers. It will be up on the web site in a few days. You can check it out later at http://www.opticsplanet.com/ray-ban-way ... asses.html .

and what is the difference between ray wayfarer 1 and 2?

- Wayfarer I or, in other words, original Wayfarer is RB 2140 . It reproduces the first model of Wayfarer sunglasses that Ray Ban made in 1952. Wayfarer II or RB2143 is a smaller version of the original Wayfarer glasses that is targeted on younger consumers. The frame comes in two tone funky colors.

is the 2 circle glass frame bigger in size for a 50mm compare to a 47mm or is it the same?

- I'm sorry I'm not sure if I understand what "2 circle glass frame" is. Could you please rephrase it?

is there a specific size for the nose bridge? they dont have sizings for that do they?

- The nose bridge size is the same for all Wayfarer glasses. It slightly varies for some other Ray-Ban models.

Please let me know if you have more questions. I will be glad to answer them all

Hey thank you so much for answering my questions i really appreciate it i have some more though hopefully you have the time to answer them haha sorry

when i meant the 2 circle frames, i meant the 2 ovals (varies in sizes depending on the glasses) holding the lens, those will ALWAYS stay the same size regardless if its 47mm and 50mm right? or is the 2 circle (oval) frames bigger if its a 50mm rather then 47mm?

Does the 47mm and 50mm determine the oval shape SIZE of the glasses?

and silly question to ask on this forum but, all the glasses from opticsplanet.com are authentic correct?

does opticsplanet have a retail store (besides online)?

THANK YOU SO MUCH AGAIN, your a big help

by the way, is the guy wearin raybans on this picture? if so which ray bans?

No problem at all

Does the 47mm and 50mm determine the oval shape SIZE of the glasses?

- 47 and 50 is an effective diameter of the lens in mm. If the lens is bigger, the ovals holding the lens are proportionally bigger as well.

and silly question to ask on this forum but, all the glasses from opticsplanet.com are authentic correct?

- OpticsPlanet sells only 100% authentic products. We do not deal with replicas and counterfits.

does opticsplanet have a retail store (besides online)?

- We do have an eyewear dispensary store, but currently we are refurbishing it. So for now we are open for on-line purchases only (please let me know if you would like me to guide you through our prescription glasses on-line ordering. I'll be glad to assist you).

-Unfortunately I am not 100% sure what brand/model of eyeglasses this guy is wearing. They look similar to Ray Ban RX 5122

Have a great Thanksgiving!

Hey thanks again, if i was to buy the rx5121 with lens (my prescription is -4.25) then how much extra would the lens be? (i only want the regular lens nothing extra)

Whould you like to get single vision or or bifocal lenses? The price varies for them.

Also, could you please give me your full prescription info? It will be easier for me to find you the most cost effective lens that will work with your Rx.

what is the difference between single vision or bifocal lense?

Single vision lenses have the same correction throughout the lens. It can be either for distance or reading.

Bifocal lenses correct vision both for reading and for distance. And they have a distinct line between distance and reading portion of the lens.

You can read more about different lens types at http://www.opticsplanet.com/prescriptio ... -info.html .

Please let me know what your prescription is and I will help you with a lens choice.

i thought the prescription was only 1 portion of numbers, which is -4.25, or is there more then that?
