What Lack of Sleep Does to Your Eyes?

Getting less than five hours of sleep every night is bad for your eyes. A good night’s sleep helps the eye function properly, and if you don’t get enough, you might be susceptible to eye spasms. This condition, known as a myokymia, is a common side effect of lack of sleep. Luckily, these spasms are not painful and will not affect your vision.

Ischemic Optic Neuropathy

Lack of sleep can contribute to the development of ischemic optic neuropathy (NA-AION). This is an inflammatory disease of the medium to large blood vessels of the eye, which results in decreased blood flow to the optic nerve. When it occurs, people may experience blurriness or even loss of vision in one eye. Lack of sleep may also result in transient ischemic attacks, which usually occur before ischemic optic neuropathy develops.

An ophthalmologist will perform an eye exam to determine if there is damage to the optic nerve. The ophthalmologist will test the eye by dilating it and looking at the optic nerve. The doctor may also test the visual field and side vision. Blood work may also be necessary to diagnose the condition. This directory can assist you with all problems of your eyes.

Dry Eye

Dry eye patients with poor sleep quality may be more likely to develop more severe symptoms. Insufficient sleep also impairs the quality and quantity of tears. Fortunately, there are some home remedies and medications available that can help manage dry eye at night. Listed below are some of them.

Sleep deprivation may impair the ability of the cornea to repair itself. This can lead to dry eye and other symptoms, such as pain, itching, and blurred vision. In severe cases, this condition may result in blindness or vision loss. Fortunately, most people with a sleep deficiency do not experience these severe conditions. In addition to dry eye, a lack of sleep may also contribute to the onset of puffy eyes, which are common symptoms of poor sleep.


Lack of sleep is a factor that may lead to cataract development. In one study, scientists observed that those with a lack of sleep were more likely to develop cataracts. In another study, a lack of sleep was a factor in the development of nuclear cataracts. However, researchers have not established a causal relationship between cataracts and sleep.

The primary symptoms of cataracts include cloudy or blurred vision. Although cataracts are relatively harmless, advanced cataracts can be harmful to the eyes. They may affect the center of the lens, causing nearsightedness and difficulty with reading. If the cataract progresses, the lens will begin to yellow and cloud, and people may find it hard to distinguish different shades of color.

Central Serous Retinopathy

Central serous retinopathy caused by insufficient sleep can be difficult to diagnose. It may take several visits to the doctor in order to confirm the diagnosis. To diagnose the condition, the doctor will perform a full dilated eye examination on both eyes and will also take retinal images. One type of scan that can help the doctor diagnose central serous retinopathy is called optical coherence tomography (OCT). This type of scan allows the physician to look at the retina at a microscopic level. It can also help identify retinal scarring and minuscule pockets of fluid.

Symptoms of central serous retinopathy can include blurred vision, blind spots, and a lack of focus. This condition can result in loss of vision and could be life-threatening if not treated promptly. This is why early diagnosis is critical. It can also lead to a faster recovery and a lower risk of permanent vision loss.

Dark Circles

Lack of sleep is one of the most common causes of dark circles around the eyes. Sleep deprivation can cause the skin under the eye to become dull, which can accentuate dark circles. In addition, lack of sleep can cause blood vessels to become exposed beneath the skin. Also, your lower eyelids can become swollen and puffy, which can also cause shadows to appear under the eye.

A cold compress can help constrict blood vessels and reduce dark circles. Another effective remedy for puffy eyes is placing cucumber slices on your eyes before bed. Cucumbers have high water content, which can soothe tired eyes. They also contain silica, a mineral essential for the formation of healthy tissue. Tea bags may also help reduce dark circles because they have antioxidant properties and stimulate blood circulation around the eyes.

Bags Under the Eye

One of the most common side effects of sleep deprivation is under-eye bags. This is caused by the blood vessels in your eyelids being dilated from lack of sleep. Since the skin around the eyes is so thin, these dilated blood vessels will appear as dark circles under your eyes.

There are many causes of under-eye puffiness. Lack of sleep, chronic stress, and poor diet can all lead to bags under the eye. Other factors include allergies, thyroid disease, connective tissue disease, and infections. Those with allergies may have more serious problems with bags under the eye.
