Off and on I will experience flashing or pulsing light in both eyes. It doesn't last longer than ten minutes each time and doesn't occur in a patterned basis. There is no pain just obstructed vision due to the lights. I am nearsighted and I use reading glasses. I drive for a living about 7 to 9 hours a day. Could this be a serious condition or is it just eye strain?
Yes, if you will use the search feature or archives you will see this is a very very common problem.
The cause can be serious including disease of the heart, brain, blood vessels or eyes. This can be a form of TIA (transient ischemic attack). The most common cause is eye or ophthalmic migraines (which don't usually have headache with them).
See an Eye MD ophthalmologist and also your personal physician.
