Thx Danny, I'll try to keep in mind your observations and fix it

Some fixes:

Hi Darko,

I'm still not convinced by the goggles.
They are horizontally still to small and vertically to wide. Also are the outer sides to thick. The thickness around the glasses are the same.
I took the liberty of drawing some lines on your models face, to point the outline from the metal frame out.

I also found this photo where you can clearly see the outline of his goggles in the dirt on his face.

I also found this photo where he wheres goggles in action. This is the posture that must be achieved.

Ok, new design from the stratch, this time only the first frame that holds the glass (so I could easy change the shape if it is still too deep vertically), there is much more pronounced oval shape than the old ones. Remember, this is only the top frame:






If you have any correction, please feel free to say

The outer border will now be more or less same thickness, except for the outer side of the eyes (as there is depression), there thickness must be slightly bigger as I had to cover that depression...

Quick test with added border on the current frame gives me this:

Hi Darko,

Sorry to be such a difficult customer
It's almost good

The insides closest to the nose are good. only the outside must be scratched a little bit, the outer and under curve must be sharper. So if you look at the markings I made. Right Hand side from the middle line to the nose is perfect. Only the left side must be a little adjusted. Try to stretch it a little further to the left, keep the under site at the line and your left and under curve will also be automatically be sharper.

Thanks for your time and effort.

Cheers,
Danny

No trouble at all I'll try to fix it

Danny, just curious as to how you are getting the proportions of the goggles. The reason I ask is, I do not see any images of the driver full on front views. I only see one image with the goggles on and it is a 3/4 view. In that image the goggles seem to form a v with a wider top while your illustration appears to show a straight line.
Also notice the the google lens is more of rounded Pentagon shape, Like the superman symbol surrounding his s. And as the strap pulls the lens back the check pushes the lens up, causing it to slant a little upwards on the outside edges.

Hi Richard,

I'm sure about the proportions of the goggles. These goggles came as wide, as in the middle in between the end of the eye, and the beginning of the ear. These goggles where so wide in order to allow the driver to look forward and still be able to watch in his back mirror at the side of this car. Would the goggles have ended on the outer side of hist eyes, it would have narrowed his site, he would have to look constantly aside, it wouldn't be very practical at the speeds they already drove. If you look at goggles of the first generation of race drivers, they would have goggles that where very narrow. Around the mid 1920 and on, as speeds went faster and faster you see the goggles go wider and wider. The reason why the underside is pointed is to see his instruments on the dashboard. You have to keep in mind that they where sitting strait in those cars, not like a modern F1 car where the driver practically lies down in the cockpit.
They where definitely not V shaped from each other, they followed the line of the eyebrow. They had a small curve that's trow, I also only wanted to point out the outer lines on Draco's drawings not the shape itself.
Unfortunately it's very hard to find any picture of that kind of goggles that sits actually on those drivers eyes.
Perhaps following picture helps.

Cheers,
Danny

And this also gives the answer how those type of glasses cover the depression in the outer corner of the eyes - border can be same thickness on all sides, cause the border does not go over that depression, but behind that depression - closer to the ears - I think this solves my problem
This last picture shows all I need to know

BTW: nice story about developement of the glasses, it clearly shows that the shape was not "random", but carefully planed...

Hey Danny, that image is a good example to me because it shows that the lens frame is not flat, but curves around the orbital socket. It also is better to illustrate where I see the V shaped boundary of the frame.
Darko, Danny, if I'm being annoying let me know, I just enjoy the process and learn a lot from working though it with you guys.
Note the red line above the lens frame. That follows the inner arc of the lens frame and forms a sort of v shape or a wing.

Not to me, more eyes see better
