Introduction

For decades, parents have warned children that sitting too close to the TV will ruin their eyesight. This belief has become one of the most widespread health myths. But is there any truth to it? Does sitting too close to a screen really damage vision permanently, or is it just an old wives’ tale? In this article, we’ll explore the science behind eye strain, screen exposure, and long-term eye health to separate fact from fiction.

 

Does Sitting Too Close to the TV Harm Your Eyes?

The short answer is no, sitting too close to the TV does not cause permanent eye damage. However, it can lead to temporary discomfort, eye strain, and fatigue.

 

Why Do People Think TV Ruins Eyesight?

This myth dates back to the 1960s when certain TV models emitted excessive radiation that could potentially harm the eyes. However, modern televisions and digital screens are designed to be safe for prolonged viewing.

 

What Happens When You Sit Too Close?

✔ Eye Strain (Asthenopia): Staring at a screen for long periods can cause eye fatigue, headaches, and blurred vision.
✔ Increased Blinking Rate: Sitting too close may lead to dry eyes due to reduced blinking.
✔ Focusing Issues: Close viewing forces the eyes to work harder, but it doesn’t permanently damage vision.

 

The Science Behind Screens and Eye Health

  1. Can TV or Screens Cause Nearsightedness (Myopia)?
  • There is no direct evidence that sitting too close to screens causes permanent myopia (nearsightedness).
  • However, prolonged screen time without breaks may contribute to myopia progression in children, but genetics play a bigger role.
  1. The Role of Blue Light
  • Myth: Blue light from screens damages eyes.
  • Truth: There is no proven evidence that blue light from screens causes permanent eye damage, but excessive exposure can disrupt sleep cycles by reducing melatonin production.
  1. How Distance Affects Eye Comfort
  • Ideal Distance: The 20-20-20 rule (taking breaks every 20 minutes, looking 20 feet away for 20 seconds) is recommended to reduce eye strain.
  • Closer Viewing Preference: Kids often sit close to screens because their eyes can focus better at near distances.

 

Does Sitting Close to a Screen Affect Children Differently?

Children and Screen Time

  • Kids have a natural ability to focus on close objects without discomfort.
  • Sitting close to the screen does not damage their eyes, but excessive screen use may contribute to myopia progression over time.

How to Protect Children’s Eyes

✔ Encourage outdoor play – Natural sunlight helps regulate eye development.
✔ Limit screen time – Follow the American Academy of Pediatrics (AAP) guidelines for age-appropriate usage.
✔ Maintain proper lighting – Reduce glare and ensure a well-lit room to prevent strain.

 

Tips to Reduce Eye Strain from Screens

✔ Follow the 20-20-20 Rule – Every 20 minutes, look at something 20 feet away for 20 seconds.
✔ Adjust Brightness – Too much brightness or glare can cause discomfort.
✔ Blink More Often – Staring at screens reduces blink rate, leading to dry eyes.
✔ Keep Screens at a Comfortable Distance – The recommended distance is at least 2 feet (60 cm) from a monitor and 4-6 feet (120-180 cm) from a TV.
✔ Use Blue Light Filters at Night – To avoid sleep disruption, limit blue light exposure before bedtime.

 

Conclusion

The belief that sitting too close to the TV damages eyesight is a myth. While it can cause temporary eye strain and discomfort, it does not lead to permanent vision loss or blindness. The real issue lies in excessive screen time, poor lighting, and lack of breaks, which can contribute to eye fatigue and possibly increased myopia in children. The best way to protect eye health is by practicing good screen habits, taking breaks, and spending time outdoors. So, the next time someone tells you that sitting too close to the TV will ruin your eyes, you can confidently tell them – it’s just a myth!

  43. When you join Crown Resorts, you’re joining over 20,000 people across our resorts in Melbourne, Perth and Sydney supporting our customers to enjoy exceptional experiences every day. The ideal environment is one where everyone feels included, respected and safe. Conclusion For many casino staff, the strike represents more than lost wages—it’s a stand for dignity and fairness in the face of corporate collapse. The UWU has warned that if management fails to present a fair and reasonable deal, strike action will escalate.
    Star told investors on Tuesday morning it had finally signed a deal with its Hong Kong partners — including one which was once linked to organised crime figures. The strike will involve staff from the gaming floor, Star-owned restaurants and bars, including Sky Deck, and the housekeeping team. Workers at The Star in Brisbane are set to strike on Friday afternoon as they fight for a better pay deal. We’re hiring Resort Audio Visual Supervisor to join The Star Brisbane, a world-class hospitality destination in the heart of the city. We’re hiring Property Operations Technicians to join The Star Brisbane, a world-class hospitality destination in the heart of the city. We’re hiring Handyperson to join The Star Brisbane, a world-class hospitality destination in the heart of the city.

    I’ve actually done this a couple times before with previous bands, where we either set up a studio in a house or rented somewhere where it was like a home studio setup. It was just like this machine that was working all around the clock every day. How did the experience of recording at a residential studio work out for the band? The band finished a major US touring schedule and toured the UK and Europe in 2023. On April 16, 2023, the band stated that Jake Abernathie, who had played with the ensemble already during several gigs, is the successor of Maggiora. On November 4, 2022, the band announced via Instagram that Maggiora had left the band, due to his duties as a member of the Toto touring band. Touring commitments throughout 2021 took in parts of Europe, including at Bospop in Weert, Netherlands, the UK in May, plus Australian and Japanese dates.
    In May 2019, the band issued their next studio album, Take Me Higher, which had been conceived and written with the new members, Henry James and Warren Murrel. In addition that year, line-up changes took place with Henry James (Schneekluth) and Warren Murel both joining the band. By this stage the band were touring both the United States and parts of Europe on a regular basis, returning periodically to California to record. In mid 2014, in between touring commitments, the band recorded a second EP, The RedBull Sessions, at RedBull Studios in Santa Monica, California. In 2013, the band released an EP, Rhythm of the Road, which was produced by Warren Huart and had been recorded at the Swing House Studios in Hollywood, Los Angeles. Robert Jon & the Wreck is an American five-piece blues rock and Southern rock band.
    Queensland Shadow Attorney-General Tim Nicholls said yesterday he thought it highly likely someone at the OLGR knew of the Bell report’s findings ahead of the licensing decision. The OLGR had waited until Wednesday — the day before The Star Brisbane’s opening — to approve a casino licence to the consortium that owns the Queen’s Wharf development. Queensland’s gambling regulator is facing questions over its licence approval for the new Star Brisbane casino two days before Star Entertainment Group was again ruled unsuitable to run a casino in New South Wales.
    Marcia Conlan, who has worked as a games dealer with Star for eight years, said the workload had increased for many staff since moving to the Queen’s Wharf site.

  44. Moreover, it offers players a massive game library of over 10,000 titles. Although the official estimate for withdrawals is one to two hours, our practical testing revealed much faster results. The platform hosts thousands of titles from major providers across slots, table games, and live dealer sections, giving a strong mix of content for different player styles. Since local casinos don’t support crypto deposits, users who want instant wallet transfers often use platforms like this. However, like most crypto casinos, checks may be issued if activity appears unusual or if larger withdrawals are requested. Many of the leading platforms support the Bitcoin Lightning Network for low-cost, instant withdrawals.
    While a high RTP is good for players, it’s not a guarantee of immediate success. So when someone wins big, that will balance out with another player(s) not having much success. RTP stands for Return To Player and represents the percentage of money bet on the game that will be paid out through wins over time. Spins are non-withdrawable and expire 24 hours after choosing Select Game. Up to $1,000 back in casino bonus if player has net loss on slots after first 24 hours.
    However, when you combine the tax with the edge gained from betting on the banker, you’re still left with a house advantage of 1.17%. The table below shows the house edge of most popular casino games, so it could be good to know them. The percentage of the house edge is always based on a possible gaming strategy. For example, in poker, players have to increase their bets when the odds favour doing so. To get the idea of betting profitability on the classic casino games, you must understand the house edge. The house edge can be focused on the game individually and on the casino as a whole.
    High‑payout casinos consistently feature games with RTPs above 98%, and these titles are the clearest indicators of where you’ll find the strongest long‑term return. Focus on higher RTP slots, check the casino’s game filters, and play with a loss limit strategy to manage your bankroll effectively. If you’re into live casino, 888 Casino has plenty to offer.
    They also host numerous online pokies tournaments with prize pools exceeding $9 million. With a library rich in online pokies, you can find almost any top title from the providers you trust, including Pragmatic Play, Skywind, NetEnt, and more. This crypto casino offers a weekend reload bonus up to $1,050 + 50 free spins, 50 weekly free spins, and 15% cashback up to $4,500 on your net losses.
    Beyond slots and table games, Neospin Casino offers various specialty games. Table games provide strategic gameplay, allowing skilled players to use different techniques. Classic games such as blackjack, roulette, baccarat, and poker are available in multiple variations. For those who enjoy traditional casino gameplay, table games at Neospin Casino offer a refined experience. Popular titles include Megaways slots, high-volatility games, and feature-rich video slots.
    There is a specific type of game that shows you the potential wins before the next spin. Yeah in Victoria they legally have to get one, they may just tear it up or it will sit in an unopened email, etc (depending on method they choose to receive it) It’s like the sports betting or horse racing punters who will tell everyone about their big wins but never talk about the losses along the way At the end of the day the variance in the machines will mean you never get any meaningful wins to be disciplined enough to walk away. Unfortunately when it comes to pokies a lot of people play out of sheer boredom so they prefer to play for hours on end. The longer you expose your money to the house edge the greater the toll (and the more assured it will be)
    Highflybet is the new kid on the block for 2026, and it’s already making significant waves in the local scene. The verification process (KYC) was also handled very quickly; I uploaded my ID and a proof of address, and it was verified within a few hours by a human agent. I also appreciated the ‘Hall of Fame’ section, which shows the biggest wins on the site—it gives you something to aim for and adds a sense of community achievement. It’s the kind of place you go when you want a more ‘authentic’ casino experience from the comfort of your couch, backed by a platform that understands the high standards of Australian players. It’s a solid, dependable platform that doesn’t cause any headaches and feels like it was designed with the end-user’s comfort in mind. When I decided to cash out my remaining $85, the process was clear, though it did take about 24 hours for the internal team to approve the request.
