Nidek uses the hot air balloon. Topcon uses the house on the prairie.
I am not sure if it's exclusive to either brand though. Both are Japanese manufacturers.

That's an autorefractor machine and it's not exactly accurate (they over-correct a lot), nor is it legal or ethical to prescribe a medical ophthalmic device with it alone. You need subjective refraction done by an eye doctor so you can get the best lenses that you need. Also you could possibly need prisms for any tropia.
Reddit has been a an archive of some of the greatest collective minds of humanity. Besides the general algorithm up voting bots hogwash, there have been some really good subreddits with excellent information from learned professionals on topics. it I wish it was preserved rather than deleted. The AskHistorians is one of my favourite professional vetted and clean subreddits, lots of academic discussions there.
But all things have a Golden Era, and then it's enshittified and fades away. As Lemmy will be one day too.
I think Toyota and Honda... maybe somebody else was developing a Hydrogen cell car. I remember seeing James May on Top Gear talking about it and driving it. It was in California. It seemed really promising and very exciting at the time that's why the memory imprinted on me a bit.
I always imagined that portable future wizard (??nuclear??) power would be as simple as unscrewing a 5 gallon cannister from the back of a vehicle and exchanging it at the power/charging station for money. Like the small 20 lb LPG cooking gas tanks. I still think that electric cars are a phase of tech that cannot be sustainable in terms of money and environmental cost and waste for too long and that it is just transitional in our quest. Hydrogen power was always supposed to be the future in my mind.
