Eye Pressure, Rubbing, and Sleep

This book is exactly what it sounds like: a calm, thorough catalog of the everyday, completely ordinary things that produce visual disturbances, so the next time one shows up you have a boring, plausible explanation ready before worry gets a chance to invent a scarier one. Boring is the goal here. Boring is good news.

When you’re anxious about a symptom, a boring explanation can feel almost unsatisfying — surely something this startling deserves a more dramatic cause? It doesn’t, almost always. The most common explanation is nearly always the correct one, and I’d like to spend this whole book making boring explanations feel as satisfying as they actually are.

Rubbing your eyes, even gently, applies direct mechanical pressure to the retina, which can produce phosphenes — those flashes or blobs of light we covered earlier in this series. This is completely normal and happens to nearly everyone who rubs their eyes with any real pressure. Rubbing your eyes when tired or itchy.

Pressing your face into a pillow. Wearing tight goggles, masks, or glasses that press on the eye area. Resting your head on your hand with pressure against a closed eye. Standing up quickly, bending over and rising, or getting out of bed suddenly can briefly affect blood flow and pressure in and around the eyes, sometimes producing a quick flash or a brief graying of vision.

This is common enough to have its own informal name — head rush — and is generally harmless, especially if brief and infrequent. A quick flash or gray-out when you stand up fast is one of the most universally experienced visual quirks there is. Nearly everyone has felt this at some point.

The transitional state between wakefulness and sleep, called hypnagogia, often produces vivid, sometimes elaborate visual imagery — colors, shapes, faces, even brief scenes. This is a well-documented, normal part of how many brains transition into sleep, not a sign of anything concerning. What do the images or lights I see while falling asleep usually look like?

Does naming this ‘hypnagogia’ change how I feel about it? Long stretches of screen time reduce blink rate, which can dry the eyes and produce blurriness, brief flickering, or visual fatigue — symptoms that can feel alarming in the moment but usually resolve with rest, blinking, or artificial tears. □ The 20-20-20 rule: every 20 minutes, look at something 20 feet away for □ Deliberate, full blinks every so often during long screen sessions.

□ Artificial tears if dryness is a frequent issue — ask a pharmacist for a gentle option. □ A brief break in dim, natural light if screen-related disturbances become frequent. Let’s end where we always do — coming back to what you can actually see, clearly, right now.

Pause wherever you are. Let your eyes rest on one object nearby — really look at it, its color, its edges. Name it silently: ‘I can see this clearly.’ Find two more things the same way. Say quietly: ‘My eyes are doing their job right now, in this moment, and that is enough.’ Rest here for a few slow breaths before you move on with your day.

Rubbing, posture changes, sleep, and screen fatigue explain the overwhelming majority of everyday visual disturbances. Boring, common, and almost always nothing to fear. Knowing the facts doesn’t replace your eye doctor. But it does replace the panic. Next in the series: When to Actually Worry — a calm, one-page guide to red-flag eye symptoms.

awake at 2 AM, phone brightness turned all the way down, googling things like “flash of light closed eyes brain tumor” with her heart pounding. She is not a doctor. She is someone who lived inside visual health anxiety long enough to finally sit down with real ophthalmology resources, real doctors, and real patience, and learn what was actually common, what was actually rare, and how to tell the difference without spiraling.

She writes gently, because she knows exactly how loud the fear gets. Every book she writes pairs plain medical explanation with a soft landing — because knowing the facts helps, but it isn’t the whole cure. The rest is learning, slowly, to trust an imperfect, wonderfully ordinary pair of eyes again.
