Yes, lack of sleep significantly affects eye pressure (intraocular pressure or IOP), with both too little and too much sleep linked to increased IOP fluctuations, especially at night, raising the risk of glaucoma by straining the optic nerve and disrupting fluid drainage, highlighting the need for 7-9 hours of quality rest for optimal eye health.
Getting too little or too much sleep can disrupt more than mood or memory. It can also create a dangerous rhythm in your eyes. One study found that your typical sleep duration directly affects intraocular pressure (IOP) and long-term glaucoma risk.
In children, increased eye pressure can be due to abnormal drain formation during pregnancy or trauma/damage to the drain.
Acute angle-closure glaucoma
Severe eye pain. Nausea or vomiting. Blurred vision. Halos or colored rings around lights.
Studies have shown that peak IOP occurs at night or in the early morning hours in two-thirds of glaucoma patients. IOP has been shown to increase by 3 to 4mm Hg when a patient is lying flat face upward.
Poor or excess fluid drainage, eye injuries, certain medications, family history, and thin or rigid corneas are all potential causes of elevated eye pressure, which increases the risk of developing glaucoma.
What does high eye pressure feel like? High eye pressure, also known as ocular hypertension, often doesn't cause noticeable symptoms. However, some individuals may experience symptoms such as mild eye discomfort, headaches, or changes in vision.
The first sign of glaucoma is often vision loss -- generally to your peripheral vision, which is also known as side vision or tunnel vision. If you start to notice vision impairment around the edges of your visual field, you should schedule an appointment with your eye doctor immediately.
Early signs of an eye stroke (retinal artery occlusion or ischemic optic neuropathy) typically involve sudden, painless vision loss or changes, most often in only one eye, including blurred vision, blind spots, floaters, or a dark shadow covering part of your sight. It often happens upon waking and is a medical emergency requiring immediate attention to potentially save sight and identify a risk for a full stroke.
Other things that can temporarily raise eye pressure include lifting heavy weights, playing wind instruments, wearing a tight necktie or using swimming goggles. If you go swimming, it's best to wear larger goggles, because smaller ones press on the orbit of the eye which increases eye pressure.
Screen time is not considered a direct cause of glaucoma progression, but research shows that prolonged device use can temporarily increase intraocular pressure, particularly in people who already have glaucoma. These pressure increases are usually temporary and return to baseline after you stop using screens.
Ocular hypertension cannot be cured, but it can be managed with medication to reduce the risk of glaucoma. People who receive treatment for ocular hypertension may be up to 50% less likely to develop glaucoma. Still, some people treated for ocular hypertension eventually develop glaucoma.
Stage One: Suspect or Early Glaucoma
At this stage, your eye pressure may be elevated, or our doctors may notice early changes to your optic nerve, but you have no vision loss yet. You will feel completely normal, and your eyes will look and feel healthy.
Chronic sleep deprivation can lead to more serious issues, including eye spasms or twitching (myokymia), blurred vision, and even double vision in severe cases. Your eyes may appear bloodshot, and you might develop dark circles or puffiness around them.
Heavy caffeine intake should be advised against due to its transient elevations in IOP, especially in genetically predisposed patients or those with a positive family history of glaucoma. Chronic alcohol consumption can lead to many systemic complications and increased risk of glaucoma.
The study showed that eye pressure was lower when the bed head was elevated at 30 degrees compared to when lying flat. However, there was not much of a significant eye pressure reduction when the head was kept up at 30 degrees using multiple pillows.
Other signs and symptoms may include:
How is an eye stroke diagnosed? An eye stroke is diagnosed during an eye exam. Your eye doctor will use specialized tools and imaging devices to obtain a clear view of your inner eye and identify signs of retinal fluid or damage.
Your eyes need healthy blood circulation and oxygen to fuel good vision. Exercise—anything that gets your heart rate up and the blood pumping from a brisk walk to a run or a Zumba class—benefits your eyes because it promotes good circulation.
Halos around lights: Rainbow-like rings around lights, especially at night, can be a red flag. Eye pain or pressure: A dull ache or intense pressure may signal acute glaucoma.
Certain inflammatory eye diseases (like optic neuritis), retinal diseases, or past injuries can also affect the optic nerve's appearance or visual field test results, making them appear similar to glaucoma.
As the disease worsens, the field of vision gradually narrows and blindness can result. However, if detected early through a comprehensive eye exam, glaucoma can usually be controlled and serious vision loss prevented.
Normal eye pressure is 11 to 21 millimeters of mercury (written as mmHg). This is the same type of measurement used in taking your blood pressure. If your ocular pressure is higher than 21 mmHg in one or both eyes at two or more visits to your eye care specialist, then you may have ocular hypertension.
Seniors (70+ years old): The normal eye pressure for 70 year olds and beyond may still fall within the 10 to 21 mmHg range, but it's closely monitored for any increases, as they are more susceptible to eye conditions like glaucoma.
