The Two-Way Link between Your Eyes and Sleep

May 29, 2024

As the media constantly reminds us to prioritize healthy living, we all know the importance of sleep. Today we’ll take a deep dive into why getting the recommended minimum amount of 7 hours of sleep is important to maintaining the health of your eyes. We’ll also consider the ways in which eye care habits help improve the quality of your sleep.


How Sleep Quality Affects the Health of Your Eyes

During sleep, blood flow to the eyes increases, facilitating the delivery of essential nutrients and oxygen. This promotes repair and regeneration and flushes out metabolic waste products. When we don’t get enough sleep, the restorative processes aren’t as efficient. 


Let’s focus on eye diseases that have been linked to insufficient sleep:


Lack of Sleep and Dry Eyes

Dry eye syndrome occurs when the eyes do not produce enough tears or when the tears evaporate too quickly, leading to discomfort, irritation, and sometimes even vision problems. 


Prolonged periods of inadequate sleep can
lead to hypertrophy of the lacrimal glands, the structures responsible for tear production. Scientists noticed that changes in lipid metabolites, secreted proteins, and free amino acid profiles were all associated with sleep deprivation. These changes were shown to have negative effects on tear composition and quality.


Furthermore, sleep deprivation has been shown to shorten tear breakup time (TBUT), which refers to the time it takes for tears to break up and evaporate from the ocular surface. A shortened TBUT is a hallmark of dry eye syndrome and can exacerbate symptoms such as burning, stinging, and blurred vision. 


On top of that, inadequate sleep can induce apoptosis, or cell death, in the corneal epithelium, further compromising the integrity of the ocular surface.


Eyelid Twitches due to Not Enough Sleep

One of the leading causes of eyelid twitches is sleep deprivation. As we discussed before, during sleep, our bodies undergo essential processes for repair, restoration, and rejuvenation. Muscles, including those controlling our eyelids, rely on adequate rest to function properly. When we deprive ourselves of sleep, our muscles can become fatigued and prone to involuntary spasms, such as eyelid twitches.


Sleep deprivation can also disrupt the function of neurotransmitters like dopamine and serotonin, which play important roles in muscle control. As a result, the muscles in our eyelids may become hyperexcitable, leading to twitching or fluttering.


Sleep Deprivation and Glaucoma

Glaucoma, often referred to as the "silent thief of sight," is a progressive disease of the optic nerve, responsible for transmitting visual information from the eye to the brain. Unfortunately, its symptoms often go unnoticed until irreversible damage has occurred. 


A
study conducted on over 6,700 individuals aged 40 and above in the United States uncovered a correlation between sleep problems and glaucoma. Participants were surveyed about their sleep patterns, including the amount of sleep they obtained, difficulties falling asleep, sleep disturbances, diagnosed sleep disorders like sleep apnea, use of sleep medication, and daytime sleepiness.


The findings were startling, to say the least. Participants who reported either extremely short (3 or fewer hours) or long (10 or more hours) sleep durations faced three times higher odds of experiencing vision loss compared to those maintaining a standard 7-hour sleep schedule.


Researchers hypothesize that disrupted sleep patterns may lead to alterations in intraocular pressure (IOP), a key risk factor for glaucoma. Moreover, sleep disturbances could contribute to systemic inflammation and oxidative stress, processes implicated in the pathogenesis of glaucomatous optic neuropathy.


Poor Sleeping Habits and Macular Degeneration

There may be a link between inadequate sleep and the development of macular degeneration, a leading cause of vision loss. To begin with, let’s talk about the anatomy of our eyes for a bit. 


The retina is located at the back of the eye. Photoreceptor cells within the retina are responsible for converting light into electrical signals. Retinal pigment epithelial (RPE) cells support the function of photoreceptors and maintain the health of the retina.


Interestingly, both photoreceptors and RPE cells are highly energy-consuming, requiring a steady supply of nutrients and oxygen to function optimally. Any disruption in their metabolic processes can have profound effects on your vision. This is where sleep enters the equation.


There is also a connection between sleep deficiency and metabolic disorders. When we don't get enough sleep, our body's metabolic balance is thrown off-kilter. This imbalance can lead to a range of health issues, including obesity, diabetes, and cardiovascular disease. But what about the eyes?


Inadequate sleep may also impair the metabolic processes within the retina, potentially increasing the risk of developing macular degeneration. Sleep deprivation can disrupt the normal functioning of photoreceptors and RPE cells, compromising their ability to efficiently utilize energy and nutrients. Over time, this metabolic dysfunction could contribute to the degeneration of the macula, the central part of the retina responsible for detailed central vision.


How Your Eye Care Routine Affects the Quality of Your Sleep

Not only do poor sleeping habits negatively affect the health of your eyes, but your poor eyecare habits may decrease the quality of your sleep, creating a vicious cycle. That is why it is best to address both of the issues for a more holistic approach to eye care.


Blue Light and Eye Strain

Natural blue daylight signals to our brains that it is time to be awake and alert. With the advent of technology, artificial blue light from screens has become ubiquitous. Our eyes, however, haven't caught up with this rapid change.


The blue light emitted by smartphones, tablets, and computers tricks our brains into thinking it's still daytime, disrupting our natural sleep patterns. If you've ever found yourself tossing and turning late at night, unable to fall asleep, your screen time might be to blame.


The solution to this modern problem is simple: reduce exposure to blue light before bedtime. We recommend that you avoid screens altogether for at least an hour before going to sleep. This will also help you avoid digital eye strain.


Using Filters and Lenses to Your Advantage

If limiting the computer screen time is not possible for you, consider using blue light filters on your devices. These filters can help mitigate the impact of blue light on your sleep cycle, allowing your brain to ease into a restful state more effectively.


Another solution is to opt for blue light-filtering
eyeglasses or contacts. If you opt for contacts,  remember to clean your lenses thoroughly and store them in a fresh solution overnight to prevent complications.

Our eyes are among the most vital organs in the body, allowing us to experience the world in vivid color and detail. Yet, many people tend to overlook early signs of eye disease until their vision becomes noticeably impaired. Eye diseases can develop silently, and when symptoms do appear, the damage may already be significant or irreversible. Understanding the most common eye diseases and recognizing their warning signs can make the difference between preserving your sight and permanent vision loss. 1. Cataracts: Clouding the Clarity of Vision Cataracts are one of the most common eye conditions, especially in adults over 60. They occur when the normally clear lens of the eye becomes clouded, leading to blurry or dim vision. While aging is the most frequent cause, other factors—such as diabetes, prolonged UV exposure, smoking, and certain medications—can accelerate their formation. Warning Signs of Cataracts ● Cloudy or blurred vision that seems like looking through a foggy window ● Sensitivity to light and glare, especially at night ● Fading or yellowing of colors ● Frequent changes in eyeglass or contact lens prescriptions ● Difficulty seeing clearly at night Cataracts usually develop slowly, and in the early stages, new glasses or improved lighting may help. However, as the cataract progresses, surgical removal of the cloudy lens and replacement with an artificial lens is the most effective treatment. 2. Glaucoma: The Silent Thief of Sight Glaucoma is a group of eye conditions that damage the optic nerve—the vital connection between your eye and brain. This damage is often caused by abnormally high pressure inside the eye (intraocular pressure). What makes glaucoma especially dangerous is its silent progression; most people experience no pain or symptoms until vision loss occurs. Warning Signs of Glaucoma ● Gradual loss of peripheral (side) vision ● Tunnel vision in advanced stages ● Sudden severe eye pain, headache, or nausea (in acute angle-closure glaucoma) ● Blurred vision or seeing halos around lights Routine eye exams are crucial for early detection because glaucoma-related vision loss is irreversible. When caught early, prescription eye drops, oral medications, laser therapy, or surgery can effectively slow or stop its progression. 3. Age-Related Macular Degeneration (AMD): Blurring the Center of Sight Age-related macular degeneration is a leading cause of vision loss in adults over 50. It affects the macula, the small central portion of the retina responsible for sharp, detailed vision. AMD does not cause complete blindness, but it can severely affect central vision, making it difficult to read, drive, or recognize faces. Warning Signs of AMD ● Blurred or fuzzy central vision ● Straight lines appearing wavy or distorted ● A dark or empty area in the center of vision ● Difficulty distinguishing fine details There are two types of AMD: dry and wet. Dry AMD progresses slowly and is more common, while wet AMD develops quickly due to abnormal blood vessel growth beneath the retina. Although there is no cure, early detection can significantly slow progression with lifestyle changes, vitamin supplements, and specialized treatments like anti-VEGF injections for wet AMD. 4. Diabetic Retinopathy: The Hidden Threat of High Blood Sugar People with diabetes are at risk of developing diabetic retinopathy, a condition caused by damage to the small blood vessels in the retina due to high blood sugar levels. This disease progresses in stages and may not show symptoms early on, but it can eventually lead to blindness if left untreated. Warning Signs of Diabetic Retinopathy ● Blurred or fluctuating vision ● Dark or empty areas in your field of view ● Difficulty seeing at night ● Sudden loss of vision in one eye ● Spots or strings (floaters) in your vision Managing blood sugar, cholesterol, and blood pressure levels is key to preventing or delaying diabetic eye disease. Regular dilated eye exams are vital, as early detection and treatments like laser therapy or injections can preserve vision. 5. Dry Eye Syndrome: More Than Just Irritation Dry eye syndrome occurs when the eyes don’t produce enough tears or the tears evaporate too quickly. Though it may sound minor, chronic dryness can cause discomfort, inflammation, and even damage the corneal surface if untreated. Warning Signs of Dry Eye Syndrome ● Stinging, burning, or scratchy sensation in the eyes ● Feeling like something is in your eye ● Redness or excessive tearing (as a reflex response) ● Blurred vision or eye fatigue ● Discomfort while reading or using digital screens Factors such as aging, hormonal changes, medications, screen time, and environmental conditions can all contribute. Artificial tears, prescription medications, and lifestyle adjustments can provide relief and protect long-term eye health. 6. Retinal Detachment: A Medical Emergency Retinal detachment occurs when the retina—the light-sensitive layer of tissue at the back of the eye—pulls away from its normal position. This is a medical emergency that can cause permanent vision loss if not treated immediately. Warning Signs of Retinal Detachment ● Sudden appearance of flashes of light ● A surge in floaters (tiny dark spots or squiggly lines) ● A shadow or curtain effect over part of your visual field ● Blurred or distorted vision Anyone experiencing these symptoms should seek emergency care from an ophthalmologist right away. Prompt surgical intervention can often restore or save vision. 7. Conjunctivitis (Pink Eye): Not Always Harmless Conjunctivitis, commonly known as pink eye, is the inflammation or infection of the conjunctiva—the clear tissue that lines the inside of the eyelid and covers the white part of the eyeball. It can result from bacterial or viral infections, allergies, or irritants. Warning Signs of Conjunctivitis ● Redness or swelling of the whites of the eyes ● Itching, burning, or irritation ● Watery or thick discharge that crusts overnight ● Gritty feeling in the eyes ● Sensitivity to light While mild cases resolve on their own, bacterial infections may require antibiotic drops. Persistent or recurring conjunctivitis should always be evaluated by an eye doctor to rule out more serious causes. 8. Keratoconus: Thinning of the Cornea Keratoconus is a progressive condition where the cornea—the clear, dome-shaped front surface of the eye—thins and bulges outward into a cone shape. This distorts vision and can make it difficult to correct with glasses alone. Warning Signs of Keratoconus ● Sudden increase in nearsightedness or astigmatism ● Blurred or distorted vision ● Sensitivity to light and glare ● Frequent changes in prescription lenses Mild cases can be managed with custom contact lenses, while advanced cases may require corneal cross-linking or even corneal transplantation. Early detection is key to slowing its progression. Why Regular Eye Exams Are Crucial Most vision-threatening eye diseases develop silently and progress gradually. By the time noticeable symptoms appear, irreversible damage may have already occurred. Regular comprehensive eye exams allow your eye doctor to detect subtle changes early and intervene before vision loss becomes permanent. Adults should schedule a comprehensive eye exam every one to two years, especially those over 40 or with risk factors such as diabetes, high blood pressure, or a family history of eye diseases. Your eyes deserve expert care and attention at every stage of life.
