Losing My Vision

My vision is getting worse and worse. I can now only be correct to 20/60 for distance and this is going to get worse, according to my doctor. I am also losing my peripheral vision - at first that was only happening in my right eye (which is now down to 50% sight) but now my it's my left one too. My near vision is classified as much worse than my distance vision and I use a telemicroscope to read but even that doesn't always help enough for me to be able to see. The scariest thing it is my vision deterioration has been so rapid lately and shows no signs of slowing down.
