What kind of light is good for the eyes?
|
Nowadays, the probability of myopia among children is very high. In fact, myopia is not entirely caused by electronic products or bad postures, it may also be caused by lights. Therefore, we must adjust the lights correctly in our lives and not let the lights be too glaring. This will protect our eyes. So what kind of light is good for the eyes? Let's take a look. First, what kind of light is good for the eyes? Our common color spectrum includes red, orange, yellow, green, blue, indigo, purple, etc. Among these different colors of light, there are different degrees of damage to the eyes: Purple light is the most harmful to the eyes. For example, the purple light installed in the community to kill mosquitoes, the arc light emitted during electric welding, and ultraviolet light, etc., these types of light are the most harmful to the eyes. Blue light, which is the closest to purple light, is also extremely harmful to the eyes. Long-term exposure to the eyes can easily cause acute damage and lead to corneal epithelial detachment. Red light, such as the dark red flames that steel workers see in steel furnaces, can cause damage to the eyes. The light in the spectrum that is least harmful to the human eye is yellow light. The most common yellow light is the dim light at dawn and the faint yellow light emitted by incandescent lamps in homes long ago. However, from an energy perspective, incandescent lamps have been explicitly eliminated by national regulations because 90% of their energy is converted into heat and only 10% is converted into light. Second, for lighting, as long as the indoor light is not too dark, ordinary LED lights are fine.Don't just turn on the desk lamp, remember to turn on the headlight as well to reduce the contrast. It is very important to pay attention to the child's degree, writing posture, and eye usage time. It is also important to increase the child's outdoor exercise. Check your child’s eyesight regularly and correct any abnormalities as soon as possible. What kind of light is good for the eyes? Most people only pay attention to the brightness of the light, thinking that as long as the brightness is enough, it is good for the eyes. This idea is unscientific and incomplete. Evaluation of lighting quality: In addition to appropriate brightness, the stability, uniformity, continuity and comfort of light color are very important. Unfortunately, many manufacturers specializing in the production of desk lamps do not pay enough attention to the above problems. Their products only vary in shape and color. Many people read and study under undesirable lighting for years, causing serious harm to their eye health. |
