Sudden vision loss in one eye can be a sign of an eye stroke. Learn the critical differences between Central Retinal Artery Occlusion (CRAO) and Branch Retinal Vein Occlusion (BRVO), why one is a medical emergency, and how early diagnosis can protect both vision and overall health.

Have you ever noticed faint, drifting shadows — like cobwebs, threads, or tiny specks — in your vision, especially against bright skies or plain walls? You might think it’s double vision, but in most cases, these “double shadows” are actually floaters or subtle ghost images inside the eye. Floaters are caused by tiny clumps or debris in the vitreous — the jelly-like substance filling your eye — casting shadows on the retina.

Subtle eye changes like puffy eyelids, dry eyes, or a slightly altered gaze may be early warning signs of Thyroid Eye Disease (TED).
