For a few months, I’ve sometimes noticed person-shaped movement in my peripheral vision at home, but when I look directly, nothing is there. What might be worth checking?
Why do I keep seeing movement out of the corner of my eye at home?

Peripheral vision is good at detecting movement but not fine detail, so a shifting shadow, reflection, or change in light can briefly look like a person. Try noticing whether it happens in particular rooms, near windows, or with certain lights on.

Since it’s recurring, I’d book a routine eye exam or talk it over with a clinician, especially if this is new for you. Fatigue, stress, migraine, medication effects, and vision changes can all be relevant, but an exam is a better way to sort out what applies.
Get urgent medical advice if you also have sudden flashes or many new floaters, a dark curtain over part of your vision, or sudden vision loss.

The home-only pattern makes the surroundings worth checking too. Look for moving branches, passing headlights, reflective surfaces, flickering bulbs, and shadows from fans or appliances. Make sure your carbon monoxide alarms work. If anyone at home has headaches, dizziness, nausea, or confusion, leave the building and contact emergency services or your local gas safety service.
