A close look at H2O2
I tried contact lenses for a couple of years, mid-2000s, and tried the "Night & Day" type that you put in for a month, non-stop. That was the theory, anyway. They'd get gummed up and I thought I was at risk of an eye infection, so I'd take them out and soak them with hydrogen peroxide solution overnight.

Now, I was VERY aware from the start that H2O2 and sensitive tissues do not mix, and there are commercial solutions that contain peroxide and come with dire warnings in large type. Nearly every time I cleaned the lenses, I was extremely careful to rinse multiple times. I'd get a minor sting, next time I inserted a lens, that went away in a minute. On one occasion, I must have skipped a step. Bad move.

To cut a long story short, I wanted to rip my eyeball out, and used a whole bottle of lens fluid in flushing it out. The lens had been rinsed several times, and must have contained something like 0.01% H2O2, but that's obviously 0.01% too much ... 8(

Aoesept. Thought it was saline, rinsed the lense and then put it in my eye. Muck Fe, that hurt...
