Many will scoff at such a small thing, not realizing that it is just about daily abuse over decades. Fact, it took two decades to figure out these covert nefarious attacks. We cleaned our backyard just yesterday, and as my wife notice a pile of leaves today at the W neighbors fence, as she went to blow it, a huge dust cloud formed. Impossible for dust to accumulate in one day, and our leaves had all dropped last month. This toxic dust will bind to your cornea and blind you, and is exactly what happened to me in Jan 2020, and I have been blind in one eye since. I have to walk everywhere and carry everything by hand since then because it is too dangerous for me to drive, as I sometimes even miss my cup when pouring coffee. I now walk anywhere from 60-100 miles a month just to survive.
