Cannot find a vendor, help with its name too...

Hello all. I do not even know the name to search properly. Shade/visor/viewer/hood...? to eliminate glare for a sonar display.
Ideally if available with a 7" LCD plain composite video monitor built-in and head straps. -No relation at all with smartphones / 3D-

The one at right :

3D printer?.

They were probably adapted from some swimming goggles. Check a discount store, second hand store or neighborhood tag sale for something suitable. You don't need a good pair - just nearly any pair.

Modern goggles (even discount goggles) have a profile more suitable for a 16x9 ratio screen rather than the round display - the ones you show look like they fit an old military field CRT radar screen.

Excellent find on your first link; rjenkinsgb, thank you ! - It is a rental place perhaps worth asking how many are available and if they can sell a few. It is a hard to find item.

Zipzap... Images at post #1 are mine; new, kept for years as unobtanium.

Will have to modify black silicone scuba masks with a section extender if no other way... The ones used with oscilloscopes are not that much light-tight and kind of flimsy.

I recall using them at sea in old radars.

Names coming to my mind without distinction: Decca / Pathfinder / Marconi.
Maybe someone involved in their service...

If the problem is that the display is washed out by sunlight, look for a computer monitor "privacy filter". 3M used to sell the same material as Vikuity film, but the rigid plastic sheet type no longer seems to be available.

This material has a non-glare hardcote surface and internally it has very thin strips of opaque material – imagine a Venetian blind, something line this:

|||||||||||||||||||||||||||||||||||||||||||||||||||||||

If you're looking through the material straight-on, you can see the display clearly. Any light coming from off-axis is blocked from reaching the display by the slats. Which direction to orient the slats depends on the light you're trying to block out. The material can be cut with scissors or a heavy-duty paper cutter.

The material is kind of like a polarizer, but the spacing between the slats is much greater and the depth of the slats is greater. It does not interfere with vision through Polaroid sunglasses.

I first came across this material to make a not-so-bright 7-segment display on a data collector visible in direct mid-day tropical sunlight. A display that was invisible was instantly sharp and clear when a piece of this material was placed in front of it.

As Nigel says, they could be 3D printed - I'd use Polyurethane filament in an appropriate hardness grade. 65 & 95 shore are readily available.

You could take a 3D scan of one using such as the Polycam app or similar, to create a 3D CAD model that could be adjusted as required and printed. Or just draw it up from scratch.
