The hazards of flicker

Strobe refers to frequently flickering television screens, lighting fixtures, etc. Its hazards are multifaceted, mainly including the following:

1、 Harm to the eyes

1. Headache and eye fatigue: Strobe can cause the eyes to constantly adjust focus, which can lead to eye fatigue over time and potentially trigger headaches. Migraine patients are abnormally sensitive to light and may be affected by bright flashes, which can also cause migraines.

2. Vision decline: Scientific research shows that even with imperceptible flicker, the retina can still detect up to200hzThe light frequency reacts to disrupt and interfere with vision. Long term exposure to flickering light, especially high-frequency flickering, may cause damage to the retina and subsequently affect vision. Although this impact may not be intuitive, the potential harm to vision accumulated over the long term cannot be ignored.

3. Dry eyes: Strobe can accelerate the evaporation of tears on the surface of the eyes, causing the eyes to feel dry. If this state persists for a long time, it may cause dry eye syndrome accompanied by itching symptoms.

4. Photogenic epilepsy: a very small proportion of people who are sensitive to light3-70HZEven short-term exposure to flickering light within the range can cause seizures.

5. Other eye problems: Long term use of electronic devices such as mobile phones and screen flicker may also cause myopia, keratitis, and other issues. Frequent rubbing of the eyes and insufficient hand hygiene may also lead to eye infections.

2、 The impact on physical and mental health

1. Impact on work, study, and life: Strobe can cause eye fatigue, vision loss, headaches, neurological fatigue, and visual blurring, leading to decreased work ability, learning efficiency, and work efficiency.

2. Causing visual illusions and work-related accidents: Under the flicker effect, mechanical motion may experience a significant slowdown or stillness, such as in the mechanical processing industry. This illusion may lead to misjudgment, damage to machinery, and even personal injury to workers.

3. The impact on special populations: For photosensitive epilepsy patients, visible flicker with large fluctuations may trigger seizures; Will increase repetitive behavior among individuals with autism.

3、 Other impacts

The flicker effect can also have other impacts on people's lives, such as affecting sleep quality and causing irritability.

To reduce the harm caused by flicker, the following measures can be taken:

•Try to avoid prolonged exposure to flickering lights, especially in environments with high frequency flicker.

•When choosing electronic devices, choose to useDCDimming technology products to reduce the irritation of flicker to the eyes.

•Regularly rest your eyes and leave the flickering environment at regular intervals to allow your eyes to rest.

•Maintain eye hygiene and avoid rubbing your eyes with your hands.
