Grey curtain over part of my vision
You look ahead and part of the view is missing. A grey or dark shade sits over one side, or creeps up from below. It may seem to move as your eye moves, or it may stay put.
The eye is filled with a clear gel. As you get older, that gel shrinks and pulls away from the back wall. The tugging can cast specks and strands into your sight, which most people call floaters.
Sometimes that pull tears the thin layer at the back of the eye. Fluid can seep behind the layer and lift it away. A lifted part sends no picture to your brain, and you see a grey curtain.
When to see someone
Any shade, curtain or dark patch across your sight needs an eye doctor the same day. Go to an eye casualty unit or emergency room, not a routine booking. Go now as well if you see a shower of new specks, bright flashes, or your vision drops fast.
The list below is drawn from our reviewed tree for eye floaters, the specks and strands many people notice. Each item carries an evidence grade, which shows how strong the research behind it is. A grey curtain still needs an eye exam first, today.
