Are LED Lights bad for your eyes?

LED lighting exists in all aspects of life and can be seen everywhere. They have become the standard lighting mode for businesses and families.

The total market share of LED lighting will reach $76 billion in 2022 and will reach $160 billion in 2026.

In short, the LED lighting scheme is one of the most practical and prominent lighting solutions at present. LED lamps play the function of protecting the environment, saving energy, and reducing resources. It brings a series of benefits to our life and environment

However, some people are still worried about whether the use of LED will have adverse effects on human health. For example, do LEDs affect our bodies? Will it affect our sleep, the safety of our eyes, etc? Is it the best alternative to instead of the fluorescent and incandescent lamps?

Therefore, we will analyze the advantages and disadvantages of using LED lighting and discuss whether they have adverse effects on our health, especially our eyes or not.

What is LED？

Let's briefly analyze the reasons for the popularity of LEDs

1: LED is the abbreviation of Light Emitting Diode in English. LED (Light Emitting Diode) is a light-emitting diode, which is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light with high brightness and great vision, clear image and bright color, good stability and low power consumption, high light efficiency and long life, and so on.

2: LEDs use solid semiconductor chips as light-emitting materials.

3: It uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine and cause photon emission to generate light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket. One end is the negative electrode, and the other end is connected to the positive electrode of the power supply so that the entire chip is encapsulated by epoxy resin. Forest Lighting brand belongs to MLS Group, which was founded in 1997 and now is the leading LED package and LED Lighting manufacturer in the world.

4: LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy-saving, environmental protection, long life, and small size. It is widely used in various fields such as indication, display, decoration, backlight, general lighting, and urban night scenes. LED can directly emit red, yellow, blue, green, cyan, orange, purple, and white light; according to different functions, it can be divided into five categories: information display, signal light, vehicle lighting, LCD backlight, and general lighting.

LED lamps are very environmentally friendly. The design of LED energy-saving and environmental protection functions has made them have a huge positive impact on the total energy consumption of the earth. LED lamps are widely used, and can be used for home and commercial use.

Is LED safety？

LED lights have different color temperatures, usually warm light, neutral light, and white light. Different color temperatures can be achieved by lamp beads. Generally speaking, the wavelength of light emitted by some lamps is blue light, and this is where the problem lies. All in all, are LEDs safe for our eyes? The answer is definitely yes.

Are LED lights harmful to our eyes?

The retina is an important part of our eyes. The principle of retinal imaging is the same as the principle of camera photography. Our eyes are equivalent to a camera, in which the cornea and lens are equivalent to the lens of the camera, the retina is equivalent to the film of the camera, and the pupil is equivalent to the camera. Due to the aperture of the camera, the cornea and lens focus the light of external objects on the retina to form an image, the optic nerve transmits light stimulation to the cerebral cortex, and the brain reflects the object seen. The retina is affected by light and is more sensitive to light. After a long time of aiming at the sun, the eyes will feel tired.

At the same time, some people worry that long-time exposure of the eyes to LED lighting will cause a series of problems However, there is no need to worry of which only when the eyes are exposed to high-intensity and high-intensity illumination for a long time can they suffer from eye diseases. . The blue light emitted from conventional LED lamps is the same as the blue light of electronic products such as mobile phones and computers that we usually use, and has limited impact on our eyes.

Are LED lighting disrupt your sleep?

Through research, our eyes respond to blue light. The response to blue light gives us a profound response to the circadian rhythm. After blue light sends a signal to our brain, it is similar to sunlight indicating that our retina and brain need to rest. It is said that excessive use of LEDs at night can bring fatigue to our eyes and affect sleep. But the blue light is not a new thing to us. Blu-ray has been present in our mobile phones, computers, and other electronic products in our daily life. We generally believe that LED lamps will not affect our sleep, but staying up at midnight to play with mobile phones, computers, and electronic products will affect our sleep. Thus, having a regular schedule for rest will help our sleep quality and eye health.

What should I do if I have a poor condition for my health?

Some people speculate that LED lamps may exacerbate the pain of physical diseases, as well as invisibly cause trouble to patients. Because some lamps will produce weak flicker.

However, the flickering of LED lamps is very fast, almost imperceptible to the naked eye, and this flickering brings us almost negligible trouble. Moreover, many LED lamps use the flicker-free driver of lighting for eye protection concerns at present.

Conclusion: LED light is good for our health and our life

Many studies have shown that LED lamps have no damaging effects on the structure of the retina of our eyes. The use of LED lamps in home and commercial environments does not present serious risks. LED lamps to have a far-reaching positive impact on us with energy-saving and environmental protection functions to create a good lighting environment and bring a better life for us.
