Thanks for this article, Gaby. I use DMSO all the time, but was never sure the dilution that would be best to try on the eyes.
I started at a 15% dilution today and the stinging is only mild. So I'll stick with that everyday and hopefully my vision improves - or at least doesn't get worse.
On a side note, I was on vacation last week and wiped out really bad on a set of spiral stairs. The injury ended up being a nasty hyper extended ankle with popped capillaries, and severe swelling. A week later after just using DMSO a few times a day (undiluted). The pain is mostly gone, and although stairs are still tough, I'm 75% mobile again.  I had almost the exact same injury in High School and it was three weeks before I could walk properly back then. The ankle is healing surprisingly quickly with the DMSO...
		
		
	 
Just an update on the DMSO 15% dilution for eye drops - big improvement for my eyesight. One aspect of the article Gaby posted was toxins in the eyes. This never occurred to me. But here in Manitoba, especially being out in a rural area during the summer, we are exposed to a large amount of agricultural chemicals constantly in spring and fall.
The first two days I tried the drops I did have a metabolic detox reaction, which I didn't expect as I use DMSO on muscles regularly. Either the drops found something in my eyes, or application to the eye gets the DMSO into the brain or nasal cavities more effectively than it does in muscle.
I found in the first two days that everything seemed brighter and I didn't have to start turning on every light in the house to see anything after dusk.
I've tried prescription glasses for a couple of years in the in 2010's, but they were always uncomfortable and couldn't get me the variable vision I needed.
What I eventually ended up using was just drug store readers, but two different pairs. 2.25 x 1 for driving and day to day work. With the 2.25 x 1, I still couldn't read a book or a screen without really angling my eyes downward. So I use 2.50 x 1 to read, but can't drive with them as everything blurs beyond 10 feet.
After a week of DMSO, I noticed I could now read fine with blue blocker 2.25 x 1's. I haven't been able to do that for more than three years at least. For driving and normal day to day vision, I didn't have any glasses weaker than 2.25 x 1, so I went to the drug store yesterday and tried out what could be the weakest magnification where I could still see clearly beyond 10 feet. 1.5 x 1 worked! 
It's been many years since I could drive and see with 1.5 x 1. Amazing improvement!
I will mention that as the day goes on and I get more tired in the evening, the blur starts to come back in. But in the morning, it all resets back to sharpness at much lower levels of magnification. Oddly, the blue blocker lenses before I used DMSO drops caused me a lot of irritation and I didn't like them. Now they increases the clarity from normal readers. Go figure...
DMSO is a life changer in so many ways. As a topical muscle anti-inflammatory, I used it all the time and never think twice about it's effectiveness.
We have an elderly Lab/Greyhound dog who's near the end of his life (15+), but still in great shape and in good health. But we noticed over the past few months, he would start having these mini-seizures that were almost like little spasms with his eyes flickering. Two nights ago he had a big enough seizure to fall off the couch and make a whimper. He was okay, but we hadn't seen that before. My wife (who uses DMSO on herself) went into her vet network looking for anti-seizure treatments. DMSO was the first thing that came up. We're rubbing it on his head now and he smells like garlic - but no mini seizure events that I've seen. Finger's crossed...
