How Bad Is It for Your Eyes to Watch Television in the Dark?

Watching television in the dark can be detrimental to your eyes, with some serious repercussions. Prolonged viewing in a dark environment affects the eye’s ability to adjust to bright light and reduces contrast sensitivity, ultimately leading to fatigue.

In addition, individuals are at greater risk of developing long-term vision problems such as myopia or nearsightedness over time due to the strain on their eyes. Furthermore, staring at a bright, illuminated screen for an extended period can cause eye irritation and contribute to vision problems.

Avoiding too much time watching television in a dark room is highly recommended to avoid potential issues.

Are You a Person Addicted to Watch TV in the Dark? Reasons and Solutions



Computers are an important part of our lives, but working on them in the dark can negatively impact our eyes. Here are some of the reasons why working in the dark is bad for our eyes, along with some solutions to mitigate this issue.

Reasons Why Working on Computers in the Dark is Bad for Your Eyes

  1. Eye Strain: Working in low light conditions can cause your eyes to strain as they have to adjust constantly to focus on different objects or screens. This leads to fatigue and headaches, both of which are caused by excessive eye strain.
  2. Blurred Vision: Dim lighting will cause your eyes to make more effort to focus, thus leading to blurred vision over time. Blurred vision could be a sign of other eye problems, such as astigmatism or presbyopia and should be checked out by an optometrist if it persists.
  3. Dry Eye Syndrome: Low lighting causes us to not blink regularly, leading to dry eyes and potential damage over time if left untreated.
  4. Computer Vision Syndrome (CVS): CVS is a group of symptoms that occurs when you spend long periods of time staring at digital screens such as computers and phones, including headaches, neck pain, fatigue, double vision and difficulty focusing due to muscle tension around your eyes.

Solutions for Working on Computers in The Dark

  1. Make sure you have adequate lighting: If possible, use natural light from windows or switch on a lamp nearby your workstation so that your computer screen is adequately illuminated without being too bright for your visual comfort level.
  2. Take frequent breaks: Taking regular breaks from looking at digital screens helps reduce eye strain and tiredness during long periods spent working with computers or laptops at your desk. Aim for five minutes away from any digital screens every hour, as this gives your eyes enough time to rest from constantly focusing on small texts or images.
  3. Use blue light filters: Blue light filters installed onto computer monitors help ease the strain placed upon our eyes since they filter out most blue lights that cause eye strain while keeping colours accurate at the same time. It was found that blue light filtering lenses were more effective than taking regular breaks when it came to reducing ocular fatigue levels among people who used computers extensively throughout their day.



What if you watch TV in dark?

The constant change in light levels causes eye strain. Dry eye syndrome can lead to eye strain and contributes to the development of glaucoma.

According to eye researchers, lighting around television can reduce strain. This led to less fatigue, visual discomfort, and faster brain responses to visual cues. Experts still recommend this remedy under the name ” bias light.”

Let’s understand it further!

We have all experienced the dreaded eyestrain that comes with watching television in a dark room. But just how bad is it for our eyes to watch TV in the dark? 

Let’s discuss why watching TV (or any other device) in a dark room can be harmful to your eyes and what steps you can take to reduce your risk. 

Reasons for Eye Strain from Watching TV in the Dark 

  1. Glare: When you are in a dimly lit room and turn on the TV, it may seem bright due to the high contrast between light and dark. This causes your pupils to contract, forcing them to work hard to adjust to the changing levels of light. As a result, your eyes become strained and tired quickly.
  2. Focusing Difficulties: In a darker environment, your eyes may struggle to focus on an image or text due to low lighting conditions. This makes it difficult for your eyes to accommodate different distances, leading them to become exhausted quickly when switching back and forth between objects.
  3. Blue Light: Many devices, like TVs and mobile phones, emit blue light, which can cause digital eye strain syndrome – also known as computer vision syndrome – which includes symptoms such as dryness, irritation, redness, and fatigue.

Solutions for Reducing Eye Strain from Watching TV in the Dark 

  1. Use Anti-Glare Screen Protectors: Applying anti-glare screen protectors on electronic devices can help reduce glare from direct or indirect light sources such as lamps or sunlight entering through a window or door nearby.
  2. Increase Ambient Lighting: Increasing ambient lighting is particularly helpful if you use laptops or tablets since they typically have smaller screens than TVs. Try opening up curtains/shades or turning on lights at night time instead of relying solely on technology devices for illumination.
  3. Take Breaks: Make sure to take regular breaks while using any type of digital device at home or work – including TVs! Taking frequent breaks helps relieve strain off of your eyeballs by allowing them some extra time off from focusing hard on one spot/object for prolonged periods.



E-readers, such as Kindles and other tablets, can be used to enjoy stories and books. However, there are potential eye health problems if they are used or viewed in the dark. This could include eyestrain, blurry vision, dry eyes, headaches, and more. 

The most common symptom of this type of eye strain is dryness or irritation around your eyes. If you find that you’re experiencing this after long periods of reading on your e-reader, it could be a sign that your eyes need a break. 

Possible Solutions for Eye Health when Using E-Readers in the Dark

Take Breaks

Take Breaks

Taking regular breaks from e-reading can be a great way to protect our eyes from long-term damage. Prolonged exposure to electronic screens can cause fatigue, dryness, and discomfort in the eyes due to the blue light these devices emit.

By taking brief breaks between pages or chapters, we can give our eyes a chance to readjust and return to their optimal focal length. This also reduces the risk of feeling headaches or “digital eyestrain” – a good reminder that modern technology should be enjoyed responsibly!

Taking breaks is a simple way of protecting ourselves so we can continue to benefit from all the wonderful services the digital world provides us with.

Light Intensity

Light Intensity

Decreasing light intensity while reading on an e-reader can be a simple but effective way to help protect one’s eyes from potential harm. Users should consider investing in a device that allows them to adjust the display brightness to match their viewing environment and even going so far as setting up an environment that helps support comfortable and natural levels of light intensity.

This should be done by avoiding direct exposure to bright sun or light sources, being aware of reflections off glossy surfaces, and steering clear of task lighting or other bright spotlights that can create unintended glare on the screen.

Decreasing light intensity in this manner will help maintain healthy and comfortable eye functions for extended use and avoid excessive strain and fatigue due to sudden shifts in illumination.

Eye Strain Symptoms

Eye Strain Symptoms

Eye strain, also known as asthenopia, is a condition that can occur when eyes become overworked due to intense use. It’s more common today than ever before due to the amount of time we spend looking at digital devices like computer monitors and smartphones.

Symptoms of eye strain include headaches, dry eyes, blurry vision, neck and shoulder pain and general fatigue.


One common symptom of eye strain is headaches. Headaches associated with eye strain usually originate from the back of the head and around the forehead area. They can be either intermittent or consistent depending on how often you’re using your eyes and how straining the activity is.

For example, if you stare at a computer screen all day long for work, then it may result in continuous headaches and sometimes even migraines. You may also experience sharp pains in your temples or behind your eyes when you move them or look around too much.

Dry Eyes

Dry eyes are another common symptom of eye strain that can be quite painful and distracting during work/study sessions or when attempting to relax after a long day.

Dryness affects our vision because our tears help lubricate the eyeball and keep it healthy; without proper lubrication, it causes irritation and discomfort to our eyes which can lead to blurred vision or spots appearing in front of us temporarily when we refocus on something further away (which is why they call it ‘floaters’).

Blurry Vision

Blurred vision is another consequence of eye strain, typically caused by poor posture while using computers or other devices, as well as not taking enough breaks throughout the day to rest our eyes properly (at least 20 minutes every two hours). This can cause slight to moderate levels of blurriness which will require regular relaxation breaks in order to improve back into normal focus range again.

Neck & Shoulder Pain

We tend to forget about our neck & shoulder muscles when working on computers for hours at a time, but these areas are very important for keeping good posture which directly affects how easily our brains interpret visual information from screens as well as general comfortability during work sessions.

Neck & shoulder pain can creep up slowly but steadily over long periods of time, resulting from hunching over keyboards too much, so make sure you take regular breaks throughout your day just like with any other muscle group in your body – stretch out those shoulders!

General Fatigue

Finally, general fatigue is a symptom of eye strain that doesn’t always get discussed but still deserves attention because it could affect other aspects of life, such as sleep quality (or lack thereof) which will have its own repercussions both physically & mentally speaking over time if gone unchecked!

One way this happens is through exhaustion caused by staring at screens without blinking enough, which leads our bodies to tire out quickly, so make sure you take frequent blinking breaks throughout usage periods with digital devices, too – this will help remind us all what’s really important: rest!


Steps to Save Your Eyesight 

We all know that taking care of our eyes is important, but it’s easy to forget about it until something goes wrong. Taking proactive steps to protect your vision now can help you avoid issues in the future. It’s never too late to start taking better care of your eyes, and here are five simple steps that can help you preserve your eye health.    

1). Wear sunglasses

Wear sunglasses

Wearing sunglasses is an essential part of keeping your eyes healthy. The sun’s ultraviolet rays can be damaging to the delicate tissue in our eyes, so protecting them from the sun is key. That’s why it’s best to choose sunglasses that block out 99 to 100 percent of both UVA and UVB radiation.

On top of that, pairing your sunglasses with a wide-brimmed hat can provide much needed extra protection for your face and eyes. Investing in a quality pair of polarized lenses is also beneficial as it reduces glare which can cause headaches and strain on the eyes over time.

Taking the necessary steps to protect your vision will help you maintain great eye health now and in the future.

2). Schedule regular checkups

Schedule regular checkups

As we age, it is important to take special care of our eyesight. Scheduling regular checkups with an optometrist is a great way to stay on top of our eye health.

During a checkup, the optometrist can detect any potential problems in early stages and make sure that we have updated prescriptions for our glasses or contacts. Having the proper prescription helps us to read text more clearly and reducing eyestrain.

It is highly recommended to have your eyes checked once a year, or even more often if there are existing issues. So don’t delay–make your appointment today and protect your vision for years to come!

3). Exercise regularly

Exercise regularly

Exercise offers many health benefits, and protecting your eyesight is one of them! Regular exercise strengthens the muscles and blood flow in your body, including those important for healthy vision.

Exercising your eye muscles is key to maintaining proper vision and focus. Integrating some active exercises into a weekly routine can help reduce eye strain, fatigue, glaucoma, and myopia. Ideally, try to do at least 30 minutes of moderate physical activity at least three or four days a week.

This could mean anything from taking a brisk walk to lifting weights or going for a swim. Exercise has further been linked to studies that conclude it can prevent age-related vision loss. Take any opportunity you can get to exercise — not just for better eye sight but for overall well-being!

4). Eat nutritious foods 

Eat nutritious foods

Preserving your vision may seem difficult, but one key way to promote healthier eyesight is by eating nutritious foods. Eating a balanced diet assists your body in resisting and fighting off conditions that endanger eye health.

Leafy greens, such as spinach, which contain lutein, can help prevent age-related macular degeneration. Furthermore, studies suggest that foods high in beta-carotene, like sweet potatoes and apricots, may also reduce the risk of this common cause of blindness.

Fish oils support eye health both directly and indirectly; not only are they filled with vitamin D and omega-3 fatty acids which help reduce the risk of glaucoma but they may also delay its onset.

Eating well is the surest manner to taking care of your eyes – start adopting this habit today and guarantee better vision for years to come!

5). Quit smoking

Quit smoking

The consequences of smoking go far beyond lung cancer and other physical health risks; smoking plays a major role in the deterioration of your eyesight. While it’s difficult to quit, following some simple steps can help you put down your smokes once and for all.

Quitting smoking has numerous benefits to your eye health, including reducing risk of cataracts, macular degeneration and uveitis. Not only will quitting reduce your ocular health risk, but also provides an extra layer of protection against stroke, heart attack, and lung disease.

Taking the proper steps to quit each day – such as identifying triggers, having a plan in place for stressful times – can make all the difference in preserving your vision and overall health. It is time to put your eyes first!


All in all, it is not advisable to watch television in complete darkness. Even though the short-term effects are harmless, prolonged exposure may lead to adverse health implications that affect your vision. It is best to turn on a dim light or invest in a good pair of blue light blocking glasses as an alternative to watching TV in the dark.

With these simple measures, you will be able to protect your eyes and benefit from a more enjoyable TV viewing experience.
