PMMA is currently the best polymer transparent material, the transmittance achieves 93%, is higher than the glass penetrability

Maybe a solution, if your ceiling is high enough is to use the pipe vertically, with strings attached to the top end. Those strings would go through pulleys fastened to the ceiling. To go in, the pipe is in 'up' position, next to the ceiling. Once you're under the pipe, you just lift it down. This way you don't risk to crack the pipe and you don't have to crawl but you have to stand up for 15 minutes.
If the ceiling is not so high you have to squat under the pipe then stand up in the pipe then lift down the pipe.

I'm sure there must be a cheaper solutions out there. I was just a randomly searching to find such tubes, while not looking into the price issues yet. I'll try if I can find something cheaper in that department.

That is a pretty good idea! You could even put another adjustable ring beneath the fixed one so that you can pull the strips close to yourself (adjust the diameter of the "curtain" from inside). Would also make it adjustable to any size of a person. To make the strips point in the right direction you just have to drill two holes at the end of each strip (in the right direction) and put one stable string through both holes and attach it to the first ring on top.

It started years ago but it got more frequent over the past few years. Now, it happens about once a week. It starts with a 2-3 days build-up phase when neck tensions keep increasing, then the migraine crisis occurs and lasts 1-3 days. Naproxen (1 to 3 pills a day) works most of the times and alleviates 50 to 90% the pain. Then I'm migraine free for a few days and the cycle starts again.
It is not really an ophthalmic migraine but more likely a cluster migraine. The pain is mostly located in varying regions of the temporal and prefrontal area. It is throbbing with heart beats.
Usually there is not prodrome, only a high sensitivity to light coupled to a sensitivity to any noise or movements, especially bending, lying down or standing up.
Aggravating factors are stress, fatigue, efforts, heat and smoking (nicotine is a vasoconstrictor). Any external stimulus becomes a source of irritation. So I cope by living in "slow motion": avoiding any extra effort and heat, moving slower, speaking less, staying in quiet environment, reducing smoking.
During acute crisis, my thinking is foggy, nausea appears and speech is a bit slurry.
How often would you use the bed and for how long?
I'm gonna do one 15-minute session a day for several months. I really hope it will fix the problem.
Fingers crossed!
