According to experts, staring at computers, tablets, and smartphone screens will not permanently damage your eyesight. However, doing so can cause some bothersome side effects, most notably computer vision syndrome (also called digital eye strain).
This is to avoid prolonged time spent in close-up vision, which can lead to eye strain and is linked to myopia. The two-hour rule. This is aiming to limit leisure or recreational screen time, outside of study or work, to less than 2 hours per day.

There is no scientific research to prove that blue light can damage the eyes or have other health effects. Likewise, there is no evidence that blue light glasses can reduce symptoms associated with looking at a digital screen for long periods.
Are computer glasses recommended? The American Academy of Ophthalmology has officially stated that it doesn't recommend blue-light blocking glasses, and cites a lack of evidence that the light coming from our screens is damaging to our eyes.
Dark mode doesn't directly reduce eye strain, but it can offer some relief. For example, in a dim setting, a bright screen has your eyes working harder. On the contrary, a dark screen in a brightly lit room will have the same effect. -Easier to read.
Wearing blue light glasses may sound like a good solution, but a recent study determined there was little evidence to support the use of blue-blocking filters in the prevention of digital eye strain.
What's a healthy amount of screen time for adults? Experts say adults should limit screen time outside of work to less than two hours per day. Any time beyond that which you would typically spend on screens should instead be spent participating in physical activity.
Vision experts generally don't consider screens as a source of permanent vision damage, even if extended use can cause eye irritation. If you only look at screens for a few hours a day and don't experience any vision issues, you probably do not need to worry.
The eyes can also get dry and irritated during long stretches of screen use. Studies show that people of all ages blink far less often when concentrating on a screen, which in turn causes the eyes to dry out. A clear and stable tear film on the eye surface is essential for clear vision.

When it comes to visual-acuity tasks and proofreading tasks, studies have shown that people with normal and corrected vision perform better with Light mode. This means that text in Light mode is clearer and quicker to understand for people with normal or corrected vision.
The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable. These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see.
Forcing a user to read white text can lead to eye strain. Why? Because the colour white stimulates all three types of colour sensitive receptors in the human eye in nearly equal amounts. This makes reading white paragraph text on dark backgrounds stressful on the eyes.
A recent study suggested that blue light-blocking glasses do not improve symptoms of digital eye strain. The American Academy of Ophthalmology does not recommend blue light-blocking glasses because of the lack of scientific evidence that blue light is damaging to the eyes.
Don't worry, you can and should wear Blue Light glasses all day long. It does not have any negative effects. It is safe to use it for as long as you want. In fact, you need to safeguard your eyes from sunlight and artificial sources of Blue Light at all times.
