I mixed a 15% strength DMSO solution using DMSO 99.995% purity with distilled water. I put three drops in each eye, waited 15 minutes, and repeated once more. It stung for a few seconds but didn't feel any worse than normal eye drops. Within an hour, my vision was noticeably brighter and clearer. On my next Ophthalmologist visit, two weeks later, the Doc couldn't find the cataracts he had previously found and tried to get me to have surgery to remove them. Instead of ruining my eyes with unnecessary surgery for a few thousand dollars, I spent maybe a penny, did it myself., and kept my original lenses.
Hippocrates: "If you are not your own doctor, you are a fool."
I have used DMSO diluted to 70% and put one drop in each eye. Yes it does burn, but it only lasts for about 20-30 seconds and is gone. You do this twice a day laying down for five to ten minutes. My cataracts are almost gone and my glaucoma has been cured. DMSO will not hurt your eyes! My vision is so much better also.
DMSO clears cataracts.
I don't have any experience topically, but internally consumed mixed with spinach clears them.
The person I know that did this method used a tsp per day of DMSO in a spinach smoothie.
