Wow, this is intersting... I have the exact same problem with one addition though... after the "lasos and oil looking coverage" once it get to about 75% coverage (can't see a thing and it's usually only in one eye, my left eye (good eye), it goes away then I usually have a REALLY bad headache... I have had these since I was about 10 and I'm 43 now.
When I was younger (10) I went to the Dr and he pretty much thought I was nuts and told my mother don't worry about it.... so, I have just delt with it. ...
Now, at 43, I still get them, about 6 times a year and I have also worn glasses most of my life... various prescriptions..
now, the last two years or so, I am getting double vision in my left eye, usually happens after being on the computer for extended periods of time... went to the Dr, checked me out and prescribed new glasses but it still happens and is getting worse...

Thank you! Thank you! I have copied this info to take with me to a Dr. visit ..... everytime I have gone to have my eyes checked, I have been "dismissed" as if I had no problems. It is extremely hurtful to stand in front of a doctor, knowing that there is some kind of a problem, whether small or large, and having him/her act like you are stupid! You are the first to actually acknowledge that there could be a problem. Again, THANK YOU!

number 1 is the most common complaint on this board. those are called "floaters" and everyone over the age of say 25 has a few. not much can be done about them. as long as they are relatively stable, you have no vision loss that doesnt return, and you dont suddenly get a lot more or a very large one, you're fine. they're annoying but not fixable.
number 2 is more interesting. if the vision comes back, then we are not talking about any kind of retinal problem. this does not sound like retinal detachment or hole or tear or anything significant. in my mind it sounds like:
1) migraine aura or "ocular migraine". a form of migraine without headache. not life or sight threatening, but would likely need rx medications (migraine meds) to control. a temporary change in blood flow to the eye from constricted or dilated blood vessels associated with a neurochemical change.
2) hypotension like postural hypotension. a temporary change in blood flow to the eye from a vascular or heart problem. would need rx bloodpressure medication (not necessarily high blood pressure medication...possibly LOW bp meds). even if you dont have high or low blood pressure, you could have quickly fluctuating blood pressure
3) carotid artery stenosis. a change in blood flow to the eye caused by cholesterol plaque buildup in the carotid artery. would need cholesterol meds and possibly blood pressure meds...maybe even a surgical procedure to increase the blood flow
you need further testing. you need to get a physical, blood work up, and testing for blood pressure, cholesterol and migraines migraines
