Visual Disturbances: Zigzag Patterns and Light Sensitivity - Ophthalmology

When looking at clouds in the sky or a surface illuminated by sunlight, one may observe a shimmering effect resembling water ripples?

---

Symptom description: Whenever I look at the sky, I experience very noticeable jagged flashes resembling water ripples.
It seems that above a certain brightness, the effect becomes more pronounced with increasing brightness.
This is especially evident on lighter surfaces; if I look at an overly bright field of vision, the water ripples are less noticeable, but it feels very glaring until the brightness drops below a certain level, at which point I can hardly see the ripples or only feel a slight sensation.
Symptom characteristics: The flashes are circular, and I can feel them extending outward from the center of my vision about 45-60%.
Beyond that, there is no flickering sensation.
Duration of symptoms: Two years.
Description of symptom characteristics: The flickering water ripples resemble flowers with distinct outlines, the color of which is slightly darker than the background, moving toward the center of vision.
It looks like a flower rapidly shrinking toward the center and then disappearing, appearing as if many petal-shaped flashes are continuously shrinking from the outside in.
The flickering occurs rapidly, and the shapes change as they shrink, creating a continuous cycle from the outer symptoms to the center before disappearing.
Timing of symptom appearance: The symptoms appear whenever the brightness exceeds a certain level, starting from a very small area (initially only the size of a petal).
As seconds pass, the flickering area enlarges until it reaches a certain size, at which point it stops expanding and continues to flicker.
Sometimes, after staying indoors for a while, I look outside at the sky and do not see these water ripple flashes (though sometimes I do).
If I walk from indoors to outdoors and look at the sky, it appears normal for about four seconds (just feeling glaring), after which the water ripples gradually increase in size.
Around 4 to 5 PM, looking at the sky does not produce water ripples.
Issues after symptoms appear: There is a slight swelling and pain in my forehead, and after looking at bright areas for a while, my eyes feel a burning sensation, and by the afternoon, I often have a headache.
Additional information: Some days, no matter how I look, there are no water ripples; even with slightly higher brightness, they may appear a little, but not as prominently as usual.
During those days, I was taking B vitamins, and it seems that the flickering sensation was less noticeable.
I wonder if it is due to a lack of certain nutrients.
Two years ago, I visited an ophthalmology clinic for a detailed examination, and the doctor said my intraocular pressure, retina, and macula were all healthy.
However, during the dilation test, I noticed extremely obvious water ripples on the wall illuminated by indoor lighting.
I mentioned this to the doctor, who said it was a normal phenomenon and suggested I check for any issues with the optic nerve.
I have researched a lot online, such as vitreous degeneration or vitreous traction, but my vision is 0.8 in the right eye and 0.7 in the left, while those symptoms typically occur in individuals with high myopia.
Later, I came across information about normal-tension glaucoma, and I wonder if I might have this condition.
I also have poor blood circulation (I hardly exercise) and feel anemic; my little finger and ring finger often feel numb.
I later read about optic nerve circulation disorders and wonder if my lack of exercise is causing poor blood circulation, leading to insufficient blood supply to the eyes.
I usually perceive things as slightly darker.
When I shower and rinse my eyes with hot water (eyes closed), it feels very comfortable, and when I open my eyes, the bathroom light appears very bright, not dark.
I would like to ask the doctor which department I should visit at a major hospital for examination and treatment, as the symptoms have persisted for two years without worsening or an increase in my prescription.
If poor circulation persists, could it damage the optic nerve? I read online that the optic nerve has self-repair capabilities, but of course, I cannot rely solely on that.
Due to various issues over the past two years, including a car accident, I have not had time to see a doctor, and I am unsure which department to consult.
These water ripples affect my enjoyment of beautiful scenery, and I want to seek thorough treatment.
In the first half of the year, due to the car accident, I rested at home for a long time, and during my hospital stay, my blood pressure was consistently at a very low level.
At that time, the flickering sensation on brighter walls was very pronounced.
My symptoms closely resemble this: http://glaucoma2014.xclub.tw/viewthread.php?action=printable&tid=563.
Additionally, I often stay up late, but I plan to start sleeping earlier (staying up late must have an impact).
I developed these symptoms about six months after consistently staying up late.
I have not exercised for about four to five years.
Thank you, doctor, for your response.
There is no rush; I just hope for a thorough treatment of my symptoms.
