Hi. I'm online and happy to answer your question today.
Are you available to chat?
There are a number of things that could be causing your symptoms. I see you are offline, so let me touch on a couple of them. First, you may be experiencing a breakdown in your ability to fuse, called an phoria/tropia. You may also be having a migraine event. Here is some information that:
A typical migraine headache starts with shimmering lights, often times they surround a blurry area or have dots or jaggedly lines associated with them. They tend to progressively increase in intensity and sometimes march across the visual field causing difficulty with reading. Many times this is then accompanied by nausea, irritability, sensitivity to bright lights and/or loud noises. After the onset of the lights (called scintillating scotomas), the headache typically starts and the light show tends to progressively go away.
Many people can have this migraine phenomenon without the headache; it is called an acephalgic migraine. Some people even start having these late in life, or may have had a few much earlier in life that behaved differently and haven't had any for decades and then begin to have them; this is not uncommon. A family history of migraines is often present as well.
This is nothing to worry about. It is not a sign of a more serious underlying condition, brain tumor or anything like that. If the episodes become so frequent that they are bothersome there are medicines that can be used to decrease their frequency or stop an episode once it has started.
In any event, the best way to sort these issues out is to have a complete eye exam by an ophthalmologist. Is it an emergency that you do this? I don't think so, but I would try to get in for an exam in the next few weeks.
Now about that brain tumor........
I bet you don't have one......why is it that everyone thinks of that as the first reason for things like this :o)? lol!
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
