Vision Issues

I am still working my way through issues I am having with all of my body. For the last few months I have had my eyes get blurry and end up with a weird visual disterbances, I mean wiggly lines and sometimes double lines. I mean I wear glasses for a lazy eye and being near sighted. But this is stuff that I keep getting bounced around between the eye specialist because I do have a weird issue cause where there is dark spots at the back of my eyes, but the eye specailist says that isn't the issue.
But all I know is I can't keep this up, the vision leaves all together and just keeps getting worse. But I can't get anything answered. I drive, there are only two drivers in my home, and I am one of them. it scares me to think I won't be able to drive or if my eyesite will randomly disappear while I am driving.
