1.Choose "warm white" lighting
The basic technology for producing white light combines short-wavelength LEDs, such as blue or ultraviolet, with a coating of yellow phosphor. The whiter or cooler the light, the greater the proportion of blue in the spectrum.
For home lighting, it is recommended to purchase "warm white" LED lighting. Warm white light refers to a color temperature of 3300-6000K. In this kind of light, red, green, and blue light content account for a certain proportion. It usually gives people a natural and comfortable feeling.
In addition, it is best for children to avoid exposure to LED light sources with high concentrations of blue light, especially before going to bed, and to minimize the use of LED screens.
2.The brightness should be appropriate and can be used with a lampshade
We all know that it is difficult for us to distinguish objects in a too dark environment, but it does not mean that the brighter the lighting, the better. Lights that are too bright or too dark will put pressure on our eye muscles and cause visual fatigue. Therefore, when choosing lighting tools, it is necessary to consider the lighting environment. The indoor lighting should be soft and not too bright or too dark.
It can also be paired with a good-looking lampshade, which not only serves as decoration but also makes the light softer and reduces blue light overflow by 1 to 2 orders of magnitude, effectively reducing damage to the eyes.
3.Lighting colors should not be too many and bright
Different colors of lights can reflect the owner's personality and aesthetics, and can also create different home environments. However, too much color can often be counterproductive. In home decoration, we should pay attention to harmony. The lighting design should not be dazzling or too contrasty. Generally speaking, the color of the home environment can have one main color.
We must be good at using the relationship between light and color. Color has a great impact on people's psychology and physiology: light colors such as beige, light blue, light gray, white, etc. can make people quiet and peaceful, adjust balance, and are beneficial to sleep; while red Bright colors such as , orange, and yellow can make people excited, so patients with high blood pressure and heart disease should use with caution.
4.Choose LED bulbs with low flicker
Strobe, simply put, means that when you look at the screen of another electrical appliance on the screen of one electrical appliance, a line image will flash on the screen of the other electrical appliance.
The lower the light bulb flicker, the less harmful it is to your eyes. But there is no flicker-free in an absolute sense. The Chinese industry standard's flicker requirement for qualified products is 3125Hz. In daily life, we can use the mobile phone camera to quickly identify the flicker of LED lights, and point the mobile phone lens at the lighted bulb. Bulbs with high flickering will appear as frequently fluctuating lines on the mobile phone screen.
Qualified LED bulbs are generally equipped with constant current chips, which can effectively reduce flicker. The price of bulbs with constant current chips will be relatively high. Therefore, when choosing LED lights, you should not be greedy for cheap, otherwise it is easy to buy inferior products.
The current mechanism of retinal damage caused by blue light is mainly believed to be related to cellular oxidative stress response.
Experiments have shown that bilberry and bilberry extract have a protective effect on retinal photoreceptor cell damage caused by LED blue light; lutein also has a protective effect on retinal damage induced by blue light in rats; it also has a protective effect on age-related macular degeneration. Some complex antioxidant, lutein-based supplement formulas have been shown to have preventive effects.
Therefore, in theory, it is very beneficial to eat more yellow fruits, vegetables and corn.
