Does light level affect vision?

Yes, lighting levels can affect vision. Inadequate or excessive lighting can cause eye fatigue and result in a variety of visual impairments.

When it comes to screen brightness, my friend constantly reduces the brightness while working on her laptop. However, this approach can be harmful to your eyesight. If the screen is too dim and you can’t see bright objects well, your eyes can start to strain. That’s where balance is important, especially when it comes to lowering contrast.

Interestingly, this issue also applies to e-books. Some manufacturers of backlit electronic devices warn that too bright a light can also cause discomfort. It is therefore important that devices provide a balance of light.

Brightness is also an issue for office monitors. People sitting at an angle to the screen often experience uneven eye strain. It’s best to look at the screen while sitting or semi-seated to avoid unnecessary strain on the eye muscles.

Use bright, high-contrast lighting in reading, work, or study areas.

Interior design now takes into account the effect of lighting on the eyes. Staggered lighting creates a more even light, which is important for comfortable viewing. Zoning lighting by height also helps create a comfortable visual environment.

Can I read lying down?

When it comes to reading while lying down, the answer is clear – it is not the best option. It is preferable to adopt a more comfortable position, such as sitting or semi-seated. This is important to maintain the correct angle of the book and to avoid unnecessary muscle strain, because the eye is an organ that adapts intelligently, being an outgrowth of the brain.

Despite the eye’s ability to adapt and read while lying down, this approach can cause additional strain, which can lead to vision problems later on, especially with constant repetition, especially in children and teenagers.

It is recommended to keep the optimal distance from the face to the book within 40-50 cm. It is recommended to hold the book in front of you with a moderate inclination, about 30-45 degrees, which will help to reduce the load on the neck and back, as well as provide better visibility of the text.

Therefore, reading with a flashlight under a blanket is not a good habit for your eyesight. It is also important to pay attention to posture, especially in the context of education. For schoolchildren, it is important to maintain proper posture: legs should be at a 90-degree angle, have a comfortable chair with back support. Fortunately, modern children’s furniture is adapted to these requirements.

The classical education system is rightly concerned with health. Lessons of 45 minutes, followed by a short break, create favorable conditions for visual comfort. Even for adults who work in offices, it is recommended to maintain eye health: if you have worked for an hour, take five minutes to rest, get away from the computer monitor, look out of the window, participate in office socializing, or just have a cup of coffee.

This is important so that your eyes can switch from the close vision inherent in monitors and devices to distant objects. The eye, as an organ, is generally tuned to perceive distant objects. Constant near viewing can increase the risk of myopia by placing an unnatural physiological strain on the eye.

Therefore, maintaining a balance of lighting and contrast, proper habits in the use of electronic devices, and regular breaks can significantly reduce the risk of vision problems.
