im yet to find anything eyewear specific when it comes to modelling. I have seen a couple where they don’t follow the actual curvature standards on YouTube. but they may start a bad habit. if you come across one please let us know!
He graz,
Thanks for your quick reply. I think I will
manage the eyewear part with the experience we have and the factories feedback. I should have been more specific, I am looking for a course to get to know rhino in general, keeping in mind I will only use it eyewear related.
i did this one and loved it https://www.udemy.com/course/rhino-3d-tutorials-from-beginner-level-to-advanced-level/

this guy had a tutorial about making an nike frame but I cant find it anymore
It was a bit confusing sometims but still the best at the time.

Thanks! I just started and will keep you updated when I am done!
Hey Phil,
Thank you so much for posting this - as an ID professional who works for an eyewear distributer (with growing investment in internal R&D for eyewear) this is an amazing resource.
Hey guys, Juan here. Ive been checking out this thread every now and then for the last two years or so. Thanks Graz (and everyone) for creating this space which has been of great help to me.
Im an Industrial Designer working as an Eyewear designer for two years approximately and Im self taught. Im working as a head designer for an eyewear startup that blends sunglasses with jewelry pieces. It has been a hard process but Ive learnt A LOT about eyewear throughout the 6 models I’ve designed.
Overall, within Rhino it has been difficult to establish a direct and easy workflow, as acetate parts are easily done with standard sufaces but metal and jewelry adornments are easier to be done using subd.
Along my journey, another difficulty that ive encountered and still didnt solved, is where to thoroughly learn all the technical stuff that usually the manufacturer adresses, like the measurements of the lenses base curves and all the science behind that.
I’d say that Rhino is by far the best software regarding eyewear design. It’s the perfect blend between hard software for manufacturing (like Autodesk Inventor) and super organic software (Like Blender). So if anyone’s having this doubt, I’d say RHINO!
I’d love to have a chat with all of you guys and create somewhat of a networking space for eyewear Designers, Manufacturers, Suppliers, Enthusiasts. I think we can all benefit from it. Personally, I’d be looking forward to hearing from super experienced designers giving me manufacturing insight.
On the other hand, I’m positive I have a lot to offer in terms of building an eyewear brand from scratch, and I became a pro in terms of realistic visualization and media assets!
thanks for this guys!
Is it too much to make a whatsapp group?

Hey Juan,
I know theres a school in milan that teaches optical design and will teach you all the tech stuff, i don’t know if its in english though. there is an english eyewear manufacturing course in france. https://mof-lunetiers.com/
to figure out a base curve radius its 523 / Base Curve = R.
I’m sure if you have any specific questions, myself and the community here would have the answers.
There’s a few WhatsApp groups out there, one that has all the independent frame makers. I can invite you to it or send you a link.
Hi Juan,
You make some valid points, and remind me of myself when I was starting out designing frames for manufacturing.
The truth is that this world is in the hands of only a few companies and ‘digital design’ is still fairly recent in the industry! Most companies still do all of their CAD work in 2D, which by the way is good enough in most cases.
As Graz pointed out, there are some technical schools regarding eye-wear design but they are courses subsidized by the government and geared to citizens (at least this is the case in Italy).
As a manufacturer myself I find that there aren’t universal rules in order to develop eyeglasses (except base curvature values, as Graz correctly explained to you) and pretty much every technical designer has its own approach and rule set on how to properly model glasses in 3D.

Maybe Start from the Glasses to get to the frame is a most basic but important advice
Hi all,
I was very excited to find this group here as it is directly linked to the design tool I love most, Rhino. Thanks for setting this up @graz.
I am an industrial designer myself and recently started working more in the eyewear sector. I found it hard to find good instructions/tutorials on what to consider when designing eyewear, how to consider geometry constraints, ergonomics, sourcing suppliers and making sure it is fit for a manufacturing, etc.
I am now considering to build a guide, possibly as a notion doc or pdf, to gather this information and just put it out there for everyone to access for free.
Would you consider this useful, and if so what would do you think needs to be in there?
Thanks and all the best!

Yes, it would be interesting to learn the basic principles. I’m not an eyewear designer, but during my career I was indirectly asked to model two types of eyewear designs, which I created without knowing the basic rules, nor did I find any useful information on the subject. So yes, I believe a PDF on this topic would be very useful to share here.
Thank you for the feedback. Is there anything in particular you struggled with when going about designing the two types of frames?
The biggest issue I encountered was related to the lenses. Regardless of the design, I kept wondering: are the lenses spherical? What diameter should they have? How should they be positioned? How thick do they need to be? Are there different sizes, or are they standardized worldwide? These were the kinds of questions that came to mind while I was sketching the design… in short, there are a thousand more questions to ask. Overall, it would be helpful to answer all the most common questions a designer might have—things that may seem obvious to someone in the field but are not at all trivial for someone coming from a completely different background.

Here, at minute 0:57, for example, you can see a lens with variable thickness. Is this something standard or an exception?
Prescription ones have different thickness I think if I look at mine that has been getting thicker over the years as my vision gets worse
Different materials, different frames.
You also have different layer coatings like anti reflective, anti glare even ones that make you see better when driving a car or have less fatigue from computer monitors
Many years ago I had an optician say they could “shave of and round the edges” to minimise weight when cut
new tech coming out to, different factors i would say determines it
Prescrition Lenses vary in thicknesses and basecurves.
Ideally you have to design your frames in a way that the optician can fit a vast variaty of Lenses.
So for RX Start with basecure 2 to 4 as a rule of thumb.
my wife has a serious high dioptre value and using conventional glass(es) would make them so thick that you would grow an extra turtle neck just to keep them on your nose. she bought a fancy light weight frame according to her wish and had glasses produced for it in Ukraine, with a Korean state of the art technology that is utilising high refractive glass (i assume) or other materials instead to make them significantly thinner. i assume the carving is part of the necessity to keep them functioning at this thickness (thinnes), but mobility is quite different with these because compared to lenses you have slightly shifting refraction/angels when you look up and down which makes it harder to walk stairs.

why not use progressive glasses?
