Mechanism of operation of neon lights

Neon lights operate based on the principle of cold cathode gas discharge. In a neon tube, there is a small amount of neon or argon gas surrounded by a phosphor coating inside the tube. When electric current passes through the gas in the tube, it ionizes (produces positive ions and electrons) the gas in the tube and creates a flow of electrons. These electrons then hit the gas atoms in the tube, causing the process to occur and emit light.

The color of the light emitted depends on the type of gas used and the coating inside the tube. The ionization that occurs in neon gas produces a reddish-orange glow, while using argon gas in combination with a phosphor coating produces a blue or white glow.

Neon lights are designed to glow brightly and have striking colors, creating an attractive effect. When looking at neon lights from afar, the naked eye does not have major problems. However, looking directly at strong and dazzling light from neon lights for long periods of time can cause eye discomfort and fatigue.

Therefore, when exposed to neon light, avoid looking directly at strong light and ensure there is enough ambient light to reduce the difference between the neon light and the surrounding environment. If you experience eye discomfort or fatigue when exposed to bright light, rest your eyes regularly and limit the time spent exposed to bright light.

Are neon lights bad for the eyes?

Neon light does not directly harm the eyes, but looking directly at strong and dazzling light from neon lights for long periods of time can cause eye discomfort and fatigue. However, it should be noted that looking at bright, bright light from any light source for long periods of time can cause eye discomfort and fatigue.

Neon lighting often has high brightness levels and vibrant colors, especially when seen from a distance. When looking directly at the strong light of neon lights, the eyes may be challenged and glare, blurriness or eye strain may occur. This can happen to any bright light source, not just neon lights.

For most people, brief exposure to neon light in normal environments does not cause major eye problems. However, people with sensitive eyes or nearsightedness may feel more uncomfortable when exposed to the glare of neon lights. To reduce the impact of bright light on your eyes, you can apply the following measures:

Avoid directly looking at the strong light of neon lights.

Ensure sufficient ambient light to reduce the difference between neon lights and the surrounding environment.

If you feel uncomfortable or tired in bright light, please rest your eyes regularly and limit your exposure to strong light.
