I am experiencing a sudden issue with my vision where I repeatedly see the appearance of insects in my field of view. These insects seem real, but upon closer inspection, I realize there is nothing actually there. The visual disturbance happens unexpectedly and causes significant discomfort and confusion. There is no physical insect, yet my eyes or brain seem to perceive them. I have not had this issue before, and it has started occurring suddenly. I would like to mention that I have a history of hypertension and thyroid-related issues, which are being managed currently. I am unsure if these conditions are related to the symptoms I am experiencing, but I thought it was important to share.
