What kind of lighting impairs vision

Many people remember from childhood the words of our mothers and grandmothers who insisted that you should not read in the evenings at dusk, otherwise your eyesight will deteriorate. Now scientists have proved that this is nothing more than a myth, but, despite this, all the same, incorrectly selected lighting can cause considerable harm to vision.

The benefits of reading in the dark

In fact, with insufficient light, the eye muscles have to exert more effort, the only way to focus on a small object. As a result, the muscles train, and it’s even more useful for them, they are able to adapt their vision more to distant, small, large objects. A logical question may arise - is it really necessary to read in the dark?

It is important to note that reading in the dark will be useful only if it is done periodically, but by no means permanently. The eye muscles are no different from the rest of the muscles of our body, because no one can swing biceps or triceps almost constantly. Moreover, too tired eyes at some point may be so tired that they simply will not be able to fulfill their function. Excessive eye strain often leads to headaches.

It is very important to observe moderation, an infrequent and very small load will not harm your eyes, but it is also impossible to tire muscles, especially unprepared ones.

The eyes feel best in a not very bright sunlight, little can replace the natural light. If you often have to read, write or do other things that require yourself increased visual attention in the dark, be sure to adhere to the following recommendations:

• It is better to give preference to fluorescent lamps;
• One lamp in a room is not enough;
• Try to choose lamps with a white-yellow spectrum.

Computer monitor

If you have to read text from the monitor in the dark, you should not do this in a dark room. Due to the sharp contrast between the light monitor and the dark room, the eyes will experience a lot of stress.

Tip

Eye muscle training is very important. In addition to reading in the dark (not every day and not often), you can perform a simple but very effective exercise. It is enough to focus your eyes on some close subject for a few seconds, and then look at a more distant one. It is easy to do this near the window, for example, first you look at some point on the glass, and then you look at the street, at a distance of about 20-30 meters.
