Bloodshot Eyes – Should You Be Concerned?

You wake up in the morning ready to start your day, only to discover that your eyes are bloodshot. That might not be surprising if you stayed up late to finish a project, had too many drinks at a party or spent time in a smoke-filled room.

But bloodshot eyes can also signal an underlying eye problem. If your eyes appear red or bloodshot, make an appointment with an eye doctor for a comprehensive eye exam to determine the cause and to receive effective treatment.

Why Do I Have Bloodshot Eyes?

When blood rushes to the front of the eye, the tiny red blood vessels on the white of the eye dilate and become visible. This makes the eyes appear red and irritated.

So why do these blood vessels dilate, causing your eyes to look bloodshot?

Bloodshot eyes tend to be caused by:

  • Dry eyes
  • Irritants such as smoke, pollen and perfume
  • Lack of sleep
  • Excessive alcohol consumption
  • Spending too much time in front of the computer

Bloodshot eyes due to lifestyle and environmental irritants may disappear on their own, or you can try to relieve them with over-the-counter eye drops or liquid tears. Lifestyle changes, such as getting more sleep, cutting down on alcohol intake and limiting screen time can often be helpful. If allergies are the culprit, oral antihistamines and antihistamine eye drops may relieve symptoms.

At other times, underlying problems requiring prompt medical attention can cause your eye’s blood vessels to dilate. The following are some of these medical conditions:

Conjunctivitis

You’ve probably heard of “pink eye.” It’s another name for infectious conjunctivitis – an infection of the conjunctiva, the thin membrane covering the eyelid and the front surface of the eye.

There are two types of infectious conjunctivitis – bacterial and viral.

If your child has conjunctivitis, they’re not alone. About 12% of kids get bacterial conjunctivitis every year. This highly contagious condition affects children and adults. In addition to reddish eyes, the following symptoms are associated with conjunctivitis:

  • Bacterial conjunctivitis – irritated eyes, swollen eyelids, eye discharge, crusty eyelids and excessive tearing
  • Viral conjunctivitis – cold or flu-like symptoms, runny nose, fever, itchy eyes, excessive tearing

If you or your child are experiencing these symptoms, it’s important to schedule a prompt appointment with an eye doctor, who can diagnose whether the conjunctivitis is viral, bacterial or due to allergies.

Depending on the diagnosis, your eye doctor will prescribe antibiotic eye drops or creams to treat bacterial conjunctivitis. The viral form may run its course after a few days, but cold compresses and non-prescription eye drops may provide relief.

Dry Eye Syndrome

If your eyes are chronically bloodshot you may have dry eye syndrome (DES). Signs of DES include:

  • Dry, irritated eyes
  • Burning or stinging eyes
  • Discharge from the eyes
  • Light sensitivity
  • A feeling you have something stuck in your eyes
  • Blurred vision
  • Watery eyes

Dry eye syndrome is most commonly caused by a blockage of the tiny meibomian glands in the eyelids. These glands secrete oil that keeps eye moisture from evaporating too quickly. Without the oil, tears dry fast, leaving your eyes feeling dry, itchy and with a bloodshot appearance.

Too much screen time, aging, certain medications such as antihistamines, and medical conditions such as Sjogren’s syndrome can cause dry eye syndrome.

In addition to any medications or in-office treatments your eye doctor recommends, make sure to get plenty of hydration, take frequent breaks from digital screens and use a humidifier in your home.

Uveitis

In addition to bloodshot eyes, if you also experience blurred vision, see floaters or your eyes feel painful, you may have an eye inflammation called uveitis. The causes of uveitis include:

  • Autoimmune or inflammatory condition
  • Infection
  • Medication side effects
  • Cancer (in rare cases)

Unfortunately, uveitis symptoms can often be mistaken for something less serious. That’s the reason it’s important to get an eye exam if your eyes are bloodshot. Left untreated, uveitis can lead to serious conditions such as retinal scarring, cataracts and vision loss.

Depending on the cause and severity, your eye doctor may treat uveitis with prescription eye drops, steroid pills, injections or eye implants.

Eye Injury

It’s vital that all eye injuries receive immediate eye care from an eye doctor.

Even a minor eye injury can cause a big red blotch to form on the white part of the eye (sclera). The cause is a broken blood vessel or a subconjunctival hemorrhage.

Although the appearance of this blood looks severe, and can make the entire white part of the eye appear bright red, a subconjunctival hemorrhage is usually painless and doesn’t cause vision loss. Any time you notice excessive blood on the eye following an eye injury, schedule an appointment with an eye doctor to assess the health of your eye.

Glaucoma

In rare cases, bloodshot eyes may signal the presence of glaucoma – a leading cause of vision loss and blindness.

While some types of glaucoma don’t show symptoms in the early phases, bloodshot eyes can indicate the type of glaucoma that requires immediate medical care. This disease causes damage to the optic nerve due to excessive pressure within the eye. When this pressure suddenly rises, the eye’s blood vessels become dilated and visible, making the eye appear red.

If you have bloodshot eyes and/or have the following risk factors for glaucoma, immediately schedule an appointment with your eye doctor.

  • Family history of glaucoma
  • Aged 60+
  • African American, Asian or Hispanic
  • Diabetes
  • High blood pressure

Q&A With Your Local Optometrist

Can I get bloodshot eyes after LASIK surgery?

LASIK surgery is highly effective minimally invasive laser eye surgery that can correct refractive errors, but like all surgical procedures, it can have side effects. Your eyes may be bloodshot or you could see halos from a few days to three weeks after surgery. Additionally, you may experience other dry eye symptoms. Eye drops and liquid tears can alleviate these symptoms, but if you have any concerns about your eyes following LASIK surgery contact your eye surgeon.

What Should I Expect from a Glaucoma Exam?

If you have a family history and/or other risk factors for glaucoma, and if your eyes look bloodshot, consider scheduling a glaucoma exam. Your eye doctor may perform the following tests:

  • Tonometry – eye pressure test
  • Gonioscopy – to see how fluid is draining out of your eye
  • Vision field test – to examine the functioning of the optic nerve
  • Dilated pupil exam – to detect any damage to the optic nerve
  • Retinal photo or OCT – digital examination of the retina and optic nerve health

Why Is My Eyelid Twitching?

What Is An Eyelid Twitch?

Myokymia, more commonly known as an eyelid twitch, occurs when the eyelid muscles spasm uncontrollably. This sensation is generally felt in either the upper or lower eyelid of one eye.

An eyelid twitch can develop for a number of reasons, and can last anywhere from a few moments to several days, depending on the underlying cause. 

Eyelid twitches are usually nothing to worry about, though persistent eyelid spasms can signal a more serious underlying condition. 

What Causes Eyelid Twitching?

There are a range of factors that could be causing your eyelid to twitch, including:

Stress.

This is the most common cause. Any type of physical or mental stress leads to the release of cortisol, a steroid hormone in the body that acts as a stimulant and puts your body into “flight or fight” mode. It can affect the nervous system in uncharacteristic ways, including making the nerves stimulate your muscles to twitch.

Fatigue.

Have you stayed awake later than usual, or are you juggling work and family commitments? Your eyelid twitch may be a sign that your body is craving a few more hours of rest and shut eye.  

Allergies.

Itchy, watery, irritated eyes can cause eyelid spasms.   

Dry eyes.

Dry, sore eyes may sometimes lead to an eyelid twitch.

Eye strain.

Eye muscle fatigue from prolonged reading or using a digital device can lead to blurry or double vision, dry eyes, headaches and, sometimes, an eyelid twitch.

Caffeine.

Consuming too much caffeine can over-stimulate your mind and body, including the muscles in your eyes.

Alcohol.

Similar to caffeine, excessive alcohol intake can have stimulating effects on your eye muscles.

Nutrient deficiencies.

According to research, a deficiency in vitamins B12 or D, or magnesium, or other electrolyte imbalance can cause an eyelid twitch. 

Blepharospasm.

This rare eye condition is caused by a neurological problem that leads to uncontrollable facial and eyelid spasms that generally worsen over time.These spasms may also cause an increase in blink rate and intensity. 

Neurological disease.

Although uncommon, an eyelid twitch can be a symptom of multiple sclerosis (MS), Parkinson’s disease or Bell’s palsy. 

How to Stop Your Eye Twitch

  • Schedule an eye exam to find out what may be causing your eyelid twitch. Your eye doctor may prescribe glasses to relieve eye strain, or recommend dry eye treatments, Botox injections or oral medication to treat the underlying problem. 
  • Practice stress-relieving activities such as yoga and deep breathing exercises, or simply take some time out of your day to relax.
  • Use eye drops to alleviate eye allergies or dry eye symptoms.
  • Take frequent breaks from the screen and consider wearing computer glasses to reduce eye strain. 
  • Limit caffeine and alcohol consumption to determine if these stimulants may be the cause of your eyelid twitch.
  • Speak with your physician to find out if you can benefit from taking nutritional supplements and to rule out a neurological disorder, especially if other symptoms are present.

 Although an eye twitch is generally not a cause for concern, if it persists for longer than a few days or you notice any changes to your vision, contact our optometric team at Optical Illusionz today to schedule an eye exam. 

Q & A

What is dry eye syndrome?

Dry eye syndrome (DES) is a chronic condition that occurs when your eyes don’t produce enough tears or the quality of your tear film is compromised. This results in a range of symptoms that may include dry, itchy, irritated eyes, and sometimes eye twitches. While mild DES can often be alleviated temporarily with over-the-counter lubricating eye drops, moderate to severe DES generally requires specialized in-office treatments.

How can I relieve eye strain after prolonged screen time?

Digital eye strain, also known as computer vision syndrome, can cause a host of uncomfortable symptoms, including headaches, eye fatigue, dry eyes and blurry vision. Computer vision syndrome may cause your eyelid to twitch. 

If limiting screen time isn’t practical on a daily basis, try to follow the 20-20-20 rule: every 20 minutes, look at something around 20 feet away for at least 20 seconds. It is also important to remember to blink frequently and to close your eyes completely. Lastly, speak to your optometrist about wearing computer glasses while you work, as they are designed to eliminate glare from the screen, and reduce eye strain.

What Is the Long-Term Impact of Virtual Learning on Children’s Eyes?

Kids, like adults, are spending more time online. At some point during the COVID-19 pandemic, many children attended school via Zoom and completed assignments online. The trend toward more screen time — whether playing games or being in touch with friends — is likely to continue even after everyone returns to the classroom. 

We already know that prolonged screen time can cause digital eye strain as well as dry eye symptoms, among other problems in children and adults. There is some indication that extended exposure to blue light may impact the development of retinal cells. However, studies on actual subjects still need to be done to establish a clear connection. 

Dry Eyes

Spending a long time in front of screens can impact how quickly our tears evaporate, because we blink around 66% less when using a computer compared to other daily activities. When tears evaporate too quickly and aren’t replenished with blinking our eyes start to feel dry and gritty. So remember to blink every few seconds to prevent your eyes from drying out!

Blue Light Exposure

Screens, such as those that appear on computers, phones and tablets emit blue light. Recent studies have shown that overexposure to blue light can damage the retinal cells at the back of your eyes. This may increase the risk of vision issues such as age-related macular degeneration which eventually leads to permanent loss of vision. 

Excess blue light has also been shown to disrupt the circadian rhythms that regulate our sleep patterns, as it tricks your internal clock into thinking that it is the middle of the day. This may lead to difficulty in falling asleep, insomnia, and daytime fatigue.

Digital Eye Strain

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain — also called computer vision syndrome. Symptoms of eye strain include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes. 

Taking frequent breaks from your screen can help reduce eye strain and neck, back and shoulder pain during your workday.

It is recommended to take at least one 10-minute break every hour. During these breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to relieve tension and muscle aches. 

Also, look away from your computer at least every 20 minutes and gaze at a distant object at least 20 feet away for at least 20 seconds. This relaxes the focusing lens inside the eye to prevent fatigue.

How to Make Virtual Learning Safer For Your Child

The following tips can lessen the impact of screens on your child’s eyes:

  • Reduce overall screen time 
  • Encourage frequent breaks
  • Use accessories that filter blue light (for example, blue light glasses)
  • Schedule regular eye exams

Make Sure Your Child Gets Routine Eye Exams

Children need comprehensive eye exams to assess the health of their eyes, correct their vision and spot potential problems which can affect learning and behavior. 

If you are concerned about the effect of virtual learning and screen time on your child’s eyes, or if you’re due for a checkup, schedule an eye doctor‘s appointment at Optical Illusionz in Houston and Pasadena. 

Q&A

What are blue light glasses?

Blue light glasses, also known as computer glasses, effectively block the transmission of blue light emitted from devices and computer screens. They often include a coating to reduce glare to further reduce eye strain. These glasses can be purchased with or without a prescription. 

What’s the 20-20-20 rule?

If you find yourself gazing at screens all day, whether your computer, smartphone, iPad or television, you’re at risk of experiencing eye strain. So make sure you schedule frequent breaks from your screen and follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. And while you’re at it, use this time to get up, walk around, and stretch.
