Can fluorescent lighting cause vision problems? Which direction should the spotlights be directed at home to benefit the eyes? Will the computer screen emit radiation to harm the eyes? How to place the TV to reduce the damage to the eyes? This article will analyze for you one by one. 1, adjust indoor lighting Although the eyes can adapt to the light intensity to adjust, but long-term in the light or blinding glare, the eyes will feel discomfort, fatigue, stinging. Light is too strong, or from an inappropriate direction to the eyes, known as glare. Reducing blinding glare can improve indoor lighting. ①Light tube problem: Light tube lighting is often criticized for its flickering light, which is not only disturbing but also causes eye fatigue and affects vision. This is due to the power supply of the old-style light tube to operate at a lower frequency, or light tube aging, the light issued by the weakened. Now the general light tube attached to a non-flashing light source, can provide a more stable lighting, plus the light tube diameter is smaller than before, more power-saving. In addition, before the end of the light tube appears black, please replace it as soon as possible, and ensure that the connection position is clean. ②Desk lighting arrangement: Sitting at a desk, if you see the light source directly in your line of sight, you will be affected by poor fluorescence and need to change the position of the light source or chair. As if the light source is adjusted to project from behind and overhead, if you are accustomed to use the right hand, the light source should be projected down from the left shoulder, in addition, reduce the contrast between the light of the desk and indoor lighting. Reduce the appearance of glare, the spotlight to the ceiling, creating reflected light for indoor lighting, the harsh glare into soft light. 2, change the computer desk arrangement So far, there is no scientific evidence that computer screens are harmful to the eyes. Computer screens do not emit ionizing radiation (such as X-rays) or non-ionizing radiation (such as ultraviolet light). However, if you look at a computer screen for a long time, your eyes will become uncomfortable and tired. Suggested Adjustments ①Change the working mode: Avoid gazing at the computer for a long time and exploit the opportunity of eye rest. ②Change the workplace: the computer desk should be lower than the general desk, the top of the screen just below the horizon, and make 10 to 20 degrees backward tilt. ③ adjust the original manuscript frame: the original manuscript frame as close to the screen as possible to minimize the head and eye focus changes. ④ Clean dust: dust will reduce the visibility of the screen. 3, do not watch TV too close to do not want to watch TV to “eyes blinded”, to comply with the following principles: ① eyes and the screen distance, at least five times the screen width. ② Do not watch TV in the dark, the TV emits too much light and dark environment contrast, will cause eye discomfort. In addition, when watching the TV color, you can find out whether the viewer has color weakness. People with red color weakness may feel that the image is greenish, while those with green color weakness may find the image too red, and those with severe color weakness may not be able to tell the difference no matter how to adjust the color. There are not many women suffering from color weakness, while about 8% of men will suffer from different degrees of color weakness. 4, eat good eyesight Scientists point out that certain vitamins help vision. And inhale too much saturated fat and cholesterol, will increase the possibility of macular degeneration.
