The ameoba thing you are seeing is called a posterior vitreous detachment/vitreous floater. This is nothing to worry about and is normal.
As to your near vision issues this, too, is normal and is called presbyopia.
I, personally, suffer from both of these same conditions.....Please allow me to explain:
You have a thick gel material in the middle of your eyes called the vitreous. Over time as it liquefies, this gel material collapses on itself, forms little clumps that you can see as dots, lines or bugs. As these clumps form the vitreous pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you may see.
It is recommended that you see your ophthalmologist to look at the retina to make sure there are no problems such as a retinal hole or tear. In most cases, there are no problems, but this exam is precautionary and allows for preventative treatment of any lesions that are found.
If you notice a sudden increase in floaters, flashes of light (like a lightning storm), a shadow/veil in the periphery of your vision, or a decrease in your vision that doesn't improve in a few minutes this can be worrisome for a retinal detachment. You would need to contact your ophthalmologist promptly in that case.
What can you do about the floaters? Well, floaters don't go away, and they don't really get worse. Over time they tend to "sink" out of your central vision and you brain "filters" them out so you don't notice them so much anymore. They almost never cause significant visual problems except, of course, if they cause a secondary retinal detachment as discussed above. The only way to decrease or remove the floaters is with a major surgery called a vitrectomy. As a retinal specialist for almost 2 decades I only do this procedure to remove floaters in extreme cases.
In January 2013 a new drug, called Ocriplasmin, was approved by the FDA to dissolve vitreous strands in a particular eye condition called vitreomacular traction. Perhaps someday this drug could be used to also remove floaters…. Only time will tell.
and here is some information on presbyopia:
You have managed to reach that wonderful stage in your life where Presbyopia (the need for reading glasses to see up close) has reared its ugly head :(
The good news? Everything is OK with your eyes :-)
The glasses are not causing the problem, nor are they making your eyes "dependent", "weak" or otherwise changing/accelerating your need for glasses.
It is perfectly normal to be experiencing the problems you are having with near vision at this point in your life.
I suggest that you to the dollar store and buy a bunch of +1.25 power reading glasses -- a bucket full will cost about the same as one pair of "prescription" glasses for reading -- and leave them all over the house, in your car etc. Personally, this is what I do :-)
As you age you will find that you will want stronger reading glasses. I, like you, started at +1.25 and now find that +2.25 work best for me.
Of course, there are always other options available to solve you near vision problems.....You could consult with an Orthopedic Surgeon and have 6 inches added to your arms lol!
does this make sense to you?
