Yes, everyone has a natural blind spot, and your brain usually fills it in. What you’re describing matches this normal blind spot, I never said otherwise, I have one too.
Hypertensive vision damage does not present like this. It is persistent, obvious across all visual environments, and only occurs after long term, uncontrolled high blood pressure, over MANY DECADES. Occasional or well controlled readings cannot cause it.
You notice it on certain high-m contrast surfaces because your brain highlights it in those situations, but it is not dangerous and is not related to hypertension.
I don’t understand how you interpreted this as possibly being caused by your blood pressure when I’ve explained in detail why it cannot be.
