Eye fatigue is becoming more and more common as an adult-and children -- Whether it\'s a computer monitor, a tablet or a smartphone, spend a lot of time focusing their eyes on the digital screen. Other factors, however, can also cause eye fatigue and lighting is one of them. Fluorescent lamps, for example, are a common form of lighting that can cause eye fatigue, especially when the light is too bright or too dark. Eye tension is not a situation, but a sign that the nerves and muscles of the eye need to rest. Common symptoms include burning, tingling, or tears in the eyes. Sometimes, this eye fatigue can result in difficulty in focusing on objects or words, or an increase in sensitivity to face light or pain after the eyes. Not resting for a few hours on a computer or digital screen is the main cause of eye fatigue. However, these eye symptoms may occur at any time when reading, sewing, painting, driving, or the eye is focused on a task for a long time. Other factors that aggravate eye fatigue include exposure to dry indoor air and where the light is harsh and bright --- Or not bright enough. During the energy crisis in 1970s, fluorescent lamps basically replaced traditional incandescent lamps, as the energy used by fluorescent lamps in the same light decreased by 25-35% and lasted more than 10 times. Despite the emphasis on LED today (light-emitting diode) Lighting, fluorescent lighting still exists in many homes, offices and commercial buildings. Almost as long as fluorescent lamps are used, safety problems have always existed. A safety issue is ultraviolet (UV) Radiation from these lights can cause health problems including eye fatigue. Despite the lack of research to check this safety issue, the Food and Drug Administration reported that UV exposure to these lights was lower than the level of concern for normal healthy people. The flashing effect of fluorescent lamps was troubled by some technical problems in the early application. Most notably, they are buzzing, flashing and blue These problems raise widespread complaints about migraine and eye fatigue. Newer, high- The frequency fluorescent lamp does not flash or hum significantly and is illuminated in a color closer to the outdoor light, which is visually easier. A small survey shows that after these newer lights are beneficial, or at least reduce the problem, pointing out complaints from workers with 50% drops of eye fatigue and headaches, the lights are low from the old High frequency fluorescent lamps- Frequency light. The brightness of indoor lighting is very bright enough to provide light for paperbased work -- Too harsh and too bright to read yourself comfortably Illuminate the computer screen Although updated, high Frequency fluorescent lamps are unlikely to cause eye fatigue, and any type of lighting is likely to be too bright to cause eye fatigue. Interior lighting needs to be adjusted to avoid excessive glare from light or windows and to avoid too Dark Light- This can also cause eye fatigue. In fact, the ambient light level of the computer chemical industry site should be about half of the traditional use level and include additional task lighting as needed. While fluorescent lamps are often accused of causing eye fatigue, even a strong light from a window or a lack of light on a digital screen can cause eye fatigue. Once you have eliminated the root cause of the problem, it is common to prevent eye strain from disappearing. If you have eye fatigue at work, talk to your manager about doing an ergonomic assessment to identify ways to reduce glare, improve lighting, and modify your desk position, monitors and chairs that optimize vision and reduce eye fatigue. At home, avoid viewing the digital screen in a bright room, and use the floor or desk lamp if indirect lighting is required. When reading or watching the digital screen, let your eyes rest every 20 minutes by changing tasks, walking or simply resting your eyes. Blink often to moisturize your eyes, and fight dry eyes with artificial tears if needed. Use a humidifier in the winter to prevent the indoor air from being too dry. Also, if you suspect that your vision needs to be corrected, please go to the eye doctor and if your eye condition is deteriorating due to workplace or home lighting, please talk to the doctor.
