On the other hand, many times this same work can lead you to spend long hours in front of the monitor. and, surely, after spending almost all day in front of one or another screen, you have felt your eyes getting dry and tired .

We believe that taking care of your visual health is something you should take into account when you are in permanent contact with screens, so we will tell you a little about why it is necessary to know how to reduce the brightness of the computer screen.

As we mentioned before, the screens of almost all electronic devices produced today emit what is known as blue light. This type of light allows the screens of your devices to consume less energy, among other benefits. However, despite these advantages, blue light is highly harmful to your eyesight.

Let’s be clear: it won’t make you blind or anything like that, but it could affect you in the medium and long term. According to a study conducted by Harvard University, although blue light from devices cannot cause considerable damage to the human eye, it does have the potential to disrupt your sleep or change some aspects of your health.

In addition to learning how to lower PC brightness, we will share with you some practical tips that are easy to apply in your daily life, so that you can take action immediately and turn them into good habits.

1. Take a break

Don’t burden your eyes. Beyond knowing how to turn down the computer brightness, it’s vital that you give your eyes a break. Whether you’re working, learning or just taking some time to check your social media, try to take a one- or two-minute break to relax your eyes. Do this at least every 20 minutes.

If possible, pamper yourself for a few minutes at the end of the day using a home remedy to relax and take care of your eyesight. You can put some classic cucumber slices on your eyelids with your eyes closed for a few minutes to refresh your eyes (you can even make a mask while you’re at it!).

You can also prepare a chamomile tea (very relaxing), put the tea bags aside when you finish, let them cool for a few minutes in the freezer and place them on your eyes while you breathe and rest. This will help to soothe and hydrate your eyes.

2. Keep your distance

While lowering the brightness of the screen will help reduce eyestrain, you still need to follow other recommendations. One of them is the distance between the screen and your eyes.

Always try to keep your eyes at least 60 cm away from the screens of your devices. The larger the screens are, the greater the distance you should keep from them, since the greater the amount of light they emit.

3. Work during the day, sleep at night

have you noticed that the less light there is in your room, the brighter your screen feels? The lighting of your work environment is a very important factor, since this way the brightness of your PC screen will not reach your eyes so directly.

Set schedules so that, as much as possible, you stop using your electronic devices before dark (yes, that includes your smartphone), or at the very least, a couple of hours before bedtime.

why? The blue light that screens radiate has harmful effects on health, such as the risk of causing a reduction in the production of melatonin, the hormone in charge of intervening in the natural sleep cycle. This is why, if you frequently use your devices during the night, screen brightness can contribute to severely affect your sleep quality and cause insomnia.

4. Hydrate your body
