The Binge Clock - How many hours it would take to binge-watch your favourite show

The American Ophthalmological Society recommends that you should give your eyes a break every 20 minutes. A proper break involves looking at an object 20 feet away for 20 seconds (the 20:20:20 rule). Now, while there are many shows with an average episode runtime of around 20 minutes, there are plenty with well over that. We all know that when we are binging our comfort shows, our eyes can end up without a break for hours on end.

Spending excessive hours staring at a screen can lead to eye strain. The blue light from screens often means you will blink less, and the movement on the screen simultaneously makes your eyes work harder to focus. To make things worse, many of us do not position the screen at an ideal distance or angle (think watching from a laptop while nestled in bed), which causes further strain on our eyes.

Significant and repeated eye strain can add up over time and often lead to lasting effects on your vision. Unfortunately, this is especially true in children who spend more and more time glued to their screens nowadays. Regular eye examinations are essential for clear, comfortable vision. Glasses or contact lenses may help you feel more comfortable in your day-to-day life if you suffer from eye strain.

So, just how much time could you spend screen-starring while binging some of the greatest shows of all time? We investigated the total screen time for your favourite shows on Tiii.me, using Rotten Tomatoe’s most recent list of top-rated shows.

Why is binge-watching TV bad for my eyes?

The problem with binge-watching shows on your TV or device is that these screens give off blue light. Blue light is short-wavelength and high-energy light, meaning it scatters more easily which means it is not as easily focused as other visible lights. Because it’s harder to focus on blue light, excess exposure to blue light can lead to eye strain. Symptoms of eye strain include sore and irritated eyes and further difficulty focusing. In severe cases, blue light can cause retina damage, leading to vision problems such as macular degeneration.

What can I do to protect my eyes and still enjoy my favourite shows?

If you start to feel eye strain from too much time spent on your screens, you might want to decrease your exposure to blue light. Here are a few ways to do that:

The obvious answer is to reduce your screen time. Take more time away from your screens or take frequent breaks to rest your eyes (remember the 20:20:20 rule).

There are such things as blue light filters, which are available for most smartphone and computer screens which decrease the amount of blue light given off by these devices.

There are also blue light or computer glasses, which block blue light from reaching your eyes. If you already own glasses, you can look into anti-reflective lenses, which reduce glare and block blue light.

Summary

Blue light is an issue, especially if you spend too much time looking at screens. This isn’t just watching your favourite show, but working at a computer screen, gaming, or scrolling endlessly on your phone are all activities that expose your eyes to blue light and can lead to eye strain. While you don’t need to give up your binge-watching habits, it might be beneficial to consider some of the recommendations above on how to reduce your exposure to blue light.

Methodology

We collated a list of the top-rated TV shows in May 2024 from Rotten Tomatoes on the following streaming platforms: Netflix, Prime, and Disney+.

We then manually ran these 150 shows through tiii.me to find out the run time of each episode, and calculate a total watch time per season.

Each show’s Rotten Tomato rating is a combined calculation of its average ‘tomatometer’ and ‘audience score’. Only shows with an average rating of 60% or more are included in our final ranking as this is what the site classifies as a ‘positive’ or ‘Fresh’ status.
