 | We all know getting enough sleep is essential for good health. Sleep affects almost all areas of our lives, from our moods to our weight. Inadequate sleep and sleep disorders can even affect our eyes. Unfortunately, most of us do not get enough sleep. According to the Centers for Disease Control and Prevention, in the United States, about one-third of adults do not get enough sleep. Everything from stress to work can interfere with getting enough rest. |
March 11 through 17 is National Sleep Awareness Week, and it’s a good reminder to focus on getting the rest we need.
How Lack of Sleep May Affect the Eyes
Lack of sleep can leave our eyes feeling tired, but that’s not all. Skimping on sleep may also have the following effects on our eyes:
Dark Circles
If you’ve ever pulled an all-nighter or fell short on sleep, you know it might show in your eyes. It’s common to have dark circles, puffiness, or red eyes from lack of sleep. It’s not entirely clear why lack of sleep causes cosmetic eye issues, but not getting enough sleep may increase the retention of fluid and blood around the eyes.
Increased Dryness
While we sleep, our bodies uses the downtime to repair cells. When it comes to our eyes, sleep deprivation may affect tear production. In one study published in the Journal of Investigative Ophthalmology & Visual Science, the results indicated that participants that had sleep deprivation had reduced tear secretion, as opposed to the control group. Reduced tear production and increased dryness can lead to a gritty and irritated feeling in the eyes.
Eye Twitching (Myokymia)
Occasional eyelid spasms or twitching is common. Involuntary eyelid spasms do not affect vision, but they can be annoying, especially if they are frequent. The spasms are a result of nerve impulses. In most cases, doctors are not sure why they occur, but according to the American Academy of Ophthalmology (AAO), eyelid twitching tends to happen most often when we are tried.

Possible Eye Complications Related to Sleep Apnea
The effects of having a poor night’s sleep from time-to-time are temporary and primarily cosmetic and annoying. If you have an untreated sleep disorder, such as obstructive sleep apnea, however, it can have serious consequences for your vision.
Sleep apnea involves pauses in breathing due to an obstruction that blocks the airway. In many cases, obstruction occurs when the soft tissues in the back of the throat relax. The pauses in breathing are brief, but they can cause oxygen levels to drop and blood pressure to rise. Over time, untreated sleep apnea can increase a person’s risk of cardiovascular disease, including a heart attack and stroke.
According to the AAO, people with sleep apnea also have a higher chance of developing certain eye problems or exacerbating existing underlying eye conditions. For example, people with untreated sleep apnea may have an increased risk of retinal problems, floppy eyelid syndrome (loose, floppy eyelids), and glaucoma. The decrease in oxygen and rise in blood pressure that can occur with sleep apnea may affect the optic nerves and may contribute to the development of glaucoma.

Here’s to wishing you great sleep!
- Keep to a regular sleep schedule: Going to bed and waking the same time each day helps your body develop a set sleep schedule. Even on days off from work, it’s important to stick to the same schedule.
- Exercise regularly: It might seem that exercise would stimulate you and prevent sleep, but getting regular exercise may help you sleep sounder. Just be sure not to exercise too close to bedtime.
- Watch your caffeine intake: Caffeine can keep you awake at night. Limit caffeine several hours before bed. Remember, coffee and energy drinks are not the only things that contains caffeine. Certain medications, chocolate, and cola also contain caffeine.
- Create the right environment for sleep: If your bedroom is not sleep-friendly, it might be hard to get a good night’s sleep. Keep the room at a temperature that is comfortable for you. Make sure it’s dark enough and quiet to help you stay asleep.
- Limit screen time before bed: Put your electronic devices away a few hours before bed. It’s helpful to give your mind a rest. Plus, the light from the devices can trick your brain into thinking it is daylight and decrease melatonin production, which plays a role in sleep.
