How are you all doing?
Today will be the last chapter of Japanese military aviation goggles!
So let's take a look!
General Partnership Yamamoto Factory
合名会社 山本製作所（Goumeigaisya yamamoto seisakujyo）
Established Yamamoto Eyeglass Lens Manufacturing in Osaka in 1911.
In 1935, the company was reorganized as an unlimited partnership and started manufacturing dustproof glasses and lenses comprehensively.
In 1941, with the advent of the wartime regime, the company became a subcontract factory for the military, manufacturing dust-proof glasses and aviation goggles for military delivery.
After the war, the company produced underwater glasses using celluloid fabric that had been hidden in a well and thus escaped being destroyed by fire.
In 1980, the company name was changed to Yamamoto Kogaku Co.
The company still produces sports-related products and dust-proof glasses under the brand name "SWANS".

East Asia Safety glass Ｍanufacture Co.
東亜安全硝子製造株式会社（Toua anzen garasu seizou kabusikigaisya）
There was also an elastic goggle strap with lace fabric like this one.（Original）
Special glass Optical Equipment Co.
特種硝子光機株式会社（Tokusyu garasu kouki kabusikigaisya）
The box has a fish symbol, but the goggles are stamped "TGK" on the body.
"TGK" is the initials of the company, Tokusyu Garasu Kouki kabusikigaisya.
These goggles are not eagle-eyed aviation goggles, but they were made in 1939.
There were also storage boxes of cylindrical and semi-coastal shapes, etc.
It seems that they also manufactured goggles for tanks.
Mitsubishi Electric Co.
三菱電機株式会社（Mitsubishi denki kabusikigaisya）
In 1941, Mitsubishi Electric developed polarized glass. They made a curved double layer of it and put gelatin in between to prevent shattering.
The use of this polarized glass completed the development of "aviation anti-glare goggles.
It is said that this reduced and diffused the reflections on the surface of the water, making it easier to spot submarines with the naked eye.
