Hi. I'm online and happy to answer your question today.
Does this occur with both eyes or is it just one eye? Have you noticed any other problems with your eyes like flashes of light or floaters? Does your vision seem to be affected in any other way?
I see that you are offline..... I'll switch over to the Q&A system. That system works a lot like 'text messaging' but, unlike the chat system, it almost never freezes up. We can continue to work on your question there. :o)
