Eyes always want to see something green? Why are it more comfortable for human eyes to see green?

When a person looks at the distant trees from the window after intense study or work, the tense nerves will suddenly relax, and the fatigue of the eyes will disappear.

Excessively bright colors can cause people to feel tired, and excessively dark colors can make people feel emotionally heavy; Reds and yellows can give a dazzling feeling, and cyan and green can give a cool and calming feeling. The absorption and reflection of light by various colors is different, red is 67 for light, yellow is 65, green is 47, and cyan only reflects 36. Because red and yellow reflect light strongly, they tend to produce flare and dazzling.

Cyan and green are more moderate in the absorption and reflection of light, so they are more suitable for the human nervous system, cerebral cortex, and retinal tissue in the eye. For example, grass and green not only absorb the harmful ultraviolet rays in bright light, but also reduce the flare caused by strong light to the eyes.

Sunlight is polychromatic light, the visible spectrum changes from red to violet, and the wavelength is grading. When sunlight enters the eye, different colors are refracted differently, which can be seen by the refraction of sunlight by a prism. Compared with other colors such as red, the refraction of green is relatively large, and the image falls in front of the retina, and the human eye is in a state of adjustment and relaxation.

The red color falls behind the retina, and it is necessary to adjust a little nervously to see clearly. In addition, the object appears green because it absorbs other light and reflects green, so its reflection of light is relatively weak compared to colors such as red and yellow, and it is comfortable.

Also, as mentioned upstairs, most of the trees are green, and they give people who want to look into the distance a target to pay attention to. In terms of the mood of the color, green also gives people a more pleasant and relaxed mood.

The main purpose is to see far. Because when a person sees closely, the image falls behind the retina, and it needs to be adjusted to make the image pull forward to see clearly. The adjustment should be forced, and the purpose of looking far is to relax the adjustment.

As a consequence of long-term adjustment, the retina tends to grow backwards in order to adapt to the image point, leading to myopia progression. This is related to defocus, adjustment fatigue. So on the one hand, you have to look far and relax, and on the other hand, you have to look at the distance and near alternately as you mentioned, some people call it pen

tonose

The aim is to give the eyes an adjustment exercise, like a dumbbell exercise. There have been relatively large experiments in Russia that have proved that it has a positive effect on the prevention of myopia. However, it is not possible to be nearsighted. Therefore, it is prevention, not **, so that myopia disappears.

Also, it's the accommodative power, not the pupils, that are exercised. Doing so also slows down the arrival of presbyopia.

Green, due to its shorter wavelength, images before the retina, prompting accommodation.

Relaxes, rests the ciliary muscles and reduces eye strain. Often.

Looking green is good for vision care.
