How Important Is a Full Night’s Sleep for Eye Health?

Most people would probably agree that there just aren’t enough hours in the day to get everything done. With work and taking care of the kids to making dinner and cleaning the house to running errands and paying bills, it’s no wonder so many people walk around feeling like zombies all day. There’s just not enough time to do all those things and still get a full night’s sleep.

In fact, most people admit to getting less than six hours of sleep a night, and there are even some who say on a good night they might get four to five hours of sleep. I’m sure you know the amount of sleep you get every night has a huge impact on your body’s health, but something you may not know is that your eye health is also greatly affected by the amount of sleep you get.

Ischemic Optic Neuropathy

If you aren’t getting a full night of sleep, you can eventually develop issues with your eyes. You could develop a condition called ischemic optic neuropathy. This condition is caused by damage that has occurred in the optic nerve due to a poor blood flow and it can cause you to experience a sharp pain in either one or both of your eyes, as well as make it difficult to see clearly.


Besides just not getting enough sleep at night, if you have sleep apnea, you are at risk of developing glaucoma. Sleep apnea, if you aren’t sure what it is exactly, is a condition that causes sporadic interruptions in your breathing while you sleep, which means you experience a lack of oxygen in those seconds when you stop breathing, and it’s often hard for people with sleep apnea to fall into a deep, restful sleep. The lack of oxygen caused by sleep apnea has been linked to the development of glaucoma.

If glaucoma develops, the optic nerve in your eyes can become damaged, which can lead to a loss in vision or even blindness. If you think you have sleep apnea or if you aren’t sure if you have it, it is wise to look into having a sleep study done. Besides affecting your eyes, sleep apnea has many other side effects to your health.

Eye Spasms

Have you ever had one of those annoying spasms that make your eyelid twitch incessantly? Those spasms have been linked to sleep deprivation. Thankfully, you won’t experience any kind of serious eye problems or vision loss from those spasms, but if you’re getting them a lot, that’s probably a sign that you need to get more sleep.

Dry Eye

Lack of sleep over a period of time can also cause your eyes to become red, swollen, and bloodshot, and develop dry eye. Dry eye occurs when your tear ducts do not produce adequate tears to keep your eyes lubricated. You might experience pain in your eyes and it could cause redness, itching, sensitivity to light, and blurry vision.

If you experience dry eye, try getting more sleep to increase tear production, but you can also use over-the-counter eye drops to help lubricate your eyes.

Eye Strain

Getting enough sleep is also important for keeping your eyes from becoming strained. If you sit in front of a computer all day at work or you read a lot or do a lot of driving, especially at night, these types of activities can contribute to eye strain.

With so many electronics taking up space in our everyday lives, it’s not really surprising that so many people experience eye strain. Think about it, you probably have your iPhone glued to your hand all day, making phone calls, texting, and playing games.

You probably also use some kind of tablet to do your work or read on, and that’s in addition to the time you probably spend on the computer or watching TV everyday. Your eyes need to rest just like your body and mind do in order to keep going and functioning properly. Sometimes that means turning off all the electronics, lying back, and resting your eyes for a bit.

It’s been recommended by many medical professionals that to avoid eye strain, you should get plenty of sleep and also rest your eyes occasionally throughout the day just by closing them for a few minutes at a time. Too much eye strain, while it won’t do any permanent damage to your eyes or vision, can cause temporary blurriness and mild pain.

Get More Sleep

In order to keep your eyes strong and healthy, it’s imperative that you get plenty of rest. Some people have difficulties falling asleep at night and other people are just so busy that getting to bed at a decent hour is a chore itself. To help you fall asleep easier, you can try a few different home remedies that are said to cause sleepiness.

You can try drinking a cup of chamomile tea before bed to help you relax. You could also try reading a book; any book will do, although if it’s a boring book, it might help you to fall asleep faster! Cut the sugars and caffeine out of your diet a few hours before bed. This may help you notice a difference in how hard it is to fall asleep.

Proper Nutrition for Eyes

Besides just getting more sleep to help your eyes, you can also try daily eye vitamins. Certain vitamins, minerals, and herbs, like those found in our Ocu-Plus Formula, have great benefits for your overall eye health ranging from reducing strain to improving your vision. Your eyes get tired just like the rest of your body does, so eating right and getting enough sleep will benefit your body and vision.
