When Can LED Lights Prove To Be Harmful?
LED lights are super safe to use if you choose the best ones for use. But, certain situations can prove harmful if you ignore some precautions. Below are some of them that you should avoid to secure yourself from the harmful effects of LEDs.
- Over Exposure To Blue Light During the Evening
If exposed to blue light in the evening hours, your body continues to produce melanopsin. It’s a hormone that helps in producing energy during the daytime. If you are overexposed to blue light, you will fail to sleep in a natural manner. LED lights and other electronic devices have a considerable amount of blue light. Its overexposure can cause harmful effects on the body.
During the evening hours, your body’s demand for melanopsin decreases. But if you keep using these lights, it alters your natural biological clock. Placing a bulb near your face makes it difficult for your body to understand the natural pattern. The longer you expose yourself to blue light, the higher the melanopsin production. This makes it difficult to adjust to the natural environment. Many cool and warm-toned LEDs nowadays lessen the harmful effects of blue lights.
- Seeing LED Bulb With Naked Eyes For A Long Time
Staring at LED bulbs with naked eyes for a long time can damage your eyes. Studies reveal that prolonged seeing LEDs cause irreparable damage to the retina cells. The radiation from the blue band causes harm, and this is the reason you should use LED lights in a limited manner. Staring at LED bulbs for more than half a minute can be dangerous, and it is best to close your eyes.
Bright LED lights are used for larger areas like parking lots, streets, and shopping malls. It is best to use lights that are not high in brightness. Even staring at a cell phone for a long time causes retina damage. A high-quality, industry-tested LED light minimizes the dangers that come with blue light. If you want to save your eyes, limited exposure to LED bulbs is essential.
- Flickering LEDs Can Disrupt Your Focus
Flickering LEDs can disrupt your focus and cause performance issues. You may also get dizziness or seizures if you are overexposed to flickering LED. The flickering lights quickly change the emission. The eyes cannot keep up, and even under strong peak light conditions, pupils do not constrict.
Your iris responds to bright light rays by narrowing the pupil. It, as a result, protects the retina and enhances how well it processes the incoming image. In low light, the iris dilates the pupil to let in as much light as possible. If you stay in the flickering lights for long, you lose your focus and might be unable to make the right decision.
It is best to know about the root causes of flickering and avoid staying there for longer. Sometimes poor wiring can cause the flickering of LEDs.
