Which is worse for your eyes: TV or smartphones?
Aestiquo aims to provide a comfortable lifestyle through home entertainment. Eye health is a crucial issue for modern people who spend long periods of time watching smartphones and television. This time, we'll take a closer look at scientific data to determine whether television or smartphones are worse for your eyes.
Main causes of eye fatigue: distance, blue light, and blinking
There are three main factors that cause eye strain: viewing distance , blue light , and blinking frequency . Let's take a look at how these factors affect your eyes.
The closer you are watching, the more strain your eyes' focusing muscles will have, leading to increased fatigue. Generally, the recommended viewing distance for a TV is 3 to 5 times the screen size, but with smartphones, most people use them at a distance of 30 to 50 cm, which puts even greater strain on the eyes.
Blue light is a type of visible light with a short wavelength and high energy, which can easily reach the retina and cause eye strain and disrupt sleep rhythms. Smartphone and television LED displays contain a lot of blue light.
Research has shown that while we normally blink about 15 to 20 times per minute, this number drops to less than half when using digital devices. When we blink less, tears evaporate faster, causing the surface of the eye to dry out, leading to itching and pain.
TV vs. Smartphone: A Scientific Comparison
A study by the Xiamen Eye Center found that using a smartphone causes twice as much eye strain as watching television , mainly due to the difference in viewing distance.
Regarding the amount of blue light emitted, Sohu's experiments confirmed that, at the same brightness setting, the blue light intensity of a smartphone is about 1.5 times that of a television . Because smartphone screens are small, the brightness per unit area tends to be higher.
Regarding the number of times we blink, there is data that shows that we blink about 5 to 8 times per minute when using a smartphone, and about 10 to 12 times per minute when watching TV. With a smartphone, the screen is small and requires concentration to see the details, so we tend to forget to blink.
These data lead us to the conclusion that smartphones are worse for your eyes than television . However, even when watching television, watching for long periods of time puts strain on your eyes, so you need to take appropriate breaks.
Aestiquo projector eye protection solution: low blue light and keystone correction
Aestiquo offers projectors with low blue light and automatic keystone correction functions to provide a home theater experience that is gentle on the eyes. We will show you how these functions protect your eyes.
Low Blue Light Function
By reducing blue light emissions by approximately 30%, it reduces strain on the retina. The guidelines of the Japan Ophthalmological Association also recommend blocking blue light, and Aestiquo projectors meet this standard.
Automatic keystone correction function
Even when projected from an angle, the screen is automatically corrected to a rectangular shape, eliminating the need for viewers to sit in an awkward position. This reduces strain on the neck and shoulders, making it less tiring to watch for long periods of time.
Aestiquo 's popular models, the P1 and Q1 , both feature these features.
| function | Aestiquo P1 | Aestiquo Q1 |
|---|---|---|
| brightness | 20,000 lumens | 15,000 lumens |
| resolution | 1080P | 720P |
| Low Blue Light | mounted | Low Blue Light Certified |
| Auto Keystone Correction | mounted | mounted |
Perfect for those who want to enjoy a big screen in their living room.

Eye Care Guidelines of the Japanese Society of Ophthalmology
After using your device for 20 minutes, look at something 20 feet away for 20 seconds to relax your eye muscles, which can effectively prevent fatigue of the focusing muscles.
Adjust screen brightness : Adjusting the screen brightness and contrast to suit the lighting conditions around you can reduce eye strain. Be careful, as viewing a bright screen in a dark room can be particularly straining.
Regular eye examinations : We recommend that people who use digital devices for long periods of time have their eyes examined at least once a year. Early detection and treatment are key to maintaining eye health.

Eye-care habits that can be practiced in everyday life
Maintain a good viewing environment : Adjust the lighting in the room appropriately to prevent glare on the device screen. Also, when using a smartphone or tablet, ensure you maintain a proper viewing distance by placing it on a desk.
Use a blue light filter : Many smartphones and computers have a function to block blue light. You can reduce the effects of blue light by enabling this function or by using blue light blocking glasses.
Stay hydrated : Dehydration is one of the causes of decreased tear production, so aim to drink 1.5 to 2 liters of water per day.
Massage around the eyes : If you experience eye strain, gently massaging the area around your eyes with your fingers can improve blood circulation and relieve fatigue.
Incorporating these habits into your daily life will help maintain eye health, especially if you spend a lot of time using devices.
Summary: Which is worse for your eyes: TV or smartphones?
The study concluded that smartphones are worse for the eyes than televisions , mainly due to the closer viewing distance, higher blue light emissions, and reduced blinking.
However, even when watching TV, long periods of continuous viewing can put strain on the eyes, so it is important to take appropriate breaks and create a good viewing environment. Aestiquo projectors are equipped with low blue light and automatic keystone correction functions to provide a large screen experience that is gentle on the eyes.
Finally, it is important to maintain eye health by following the guidelines of the Japanese Ophthalmological Association, practicing the 20-20-20 rule, and improving your viewing environment. At Aestiquo , we provide the best products and advice to make your home entertainment life more comfortable.
