I am a 66 yr old female and years ago experienced flashing lights in my eyes. Was told I had vitreal detachment. This week I had lights again in my right eye which went away within an hr or so but now I have some blurred distance vision ... up close vision seems about the same. I do have cataracts which are not quite to surgery level. I have also had some general feelings of malaise this week, including headache, stiff neck and my eyes are tender to pressure.
