Eye protection - lighting

Human eyes develop and grow under natural light. For people, the best light source is scattered natural light.

The goal of all "eye protection lights" is to make the lights emit light as close as possible to the characteristics of natural light.

In life, the light emitted by most artificial light sources is not stable but flickers rapidly.

The common incandescent lamp strobe is generally 50 Hz, that is, the light will flicker 50 times per second. With every flicker, our pupils will shrink and expand once, which will virtually increase the burden of using our eyes, and our eyes will feel tired.

The main factors to consider when buying a lamp:

1. Illumination. At least above 300Lux, the greater the luminous flux, the greater the illuminance in the same distance test.

2. Stroboscopic, that is, the frequency of light flashing. If the light flashes badly, you can take a photo or video with the camera of your phone, and you will find that there will be flashes of light on your camera. This is stroboscopic light. Flash.

3. Blue light. When it comes to blue light, many people think that blue light is “harmful and hurts the eyes”, but it is a bit futile to talk about toxicity without the dose. There is also blue light in the sun. Only when the eyes are staring for a long time, the high-intensity blue light keeps watching, so that your eyes can cause damage. Studies have found that blue light irradiation can cause damage to retinal cells, among which short-wave blue light with a wavelength between 400 and 480 nanometers is the most harmful.

4. Color rendering index, that is, the degree of light restoration of the color of the object itself. The color rendering index is generally represented by Ra. For example, Ra80 means that the color rendering index is 80, and the Ra value of sunlight is 100. The closer the color rendering index is to 100, the better the color reproduction of this lamp is.

5. Color temperature, that is, the temperature of light. For example, the cold light and warm light we often say are all color temperatures. The light with high color temperature is whitish and colder, making it easy to focus. The light with a low color temperature is yellowish and warmer. This kind of light is easy to relax, such as the light in some lounge/bedroom. The color temperature of the lamp suitable for readers should be kept at about 4000K.

On the whole, blue light in daily life is not worthy of your special vigilance. Many other factors can even affect the health of the eyes, such as sunlight.

It's just that, after all, many things have a long-term impact, just as the agency mainly recommends restrictions, especially for flashlights, car headlights, and blue light in some devices. Their risks are relatively high.

In addition, the color temperature of the lighting should be lower than 3000K. Be wary of blue light at night, even if the amount of light is relatively small, it may still affect the sleep rhythm and cause insomnia.

Although the backlights of computers, smartphones, and tablets also have a certain amount of blue light, the overall harm is not great.

It's just that teenagers and children need to be extra vigilant because of the imperfect lens development, and blue light is more likely to act on the retina. In particular, certain sensitive people may bring headaches, visual fatigue, and other risks, and be more careful.
