Are LED Lights Harmful To Eyes

A couple of years ago, Spanish researchers discovered that blue led lights could destroy retinal’s cells. This is not the first time people criticize lighting as incandescent and fluorescent have proven to give out ultraviolet rays that can harm people.

While manufacturers hand out evidence to prove that their products’ lights are innocuous to the eyes, are their proofs credible? Are LED lights harmful to eyes? Let Best Led Lights accompany you in discovering the truth.

Are LED Lights Harmful To Eyes?

The answer is YES. LED light can cause harm to the retina of our eyes, with other symptoms like headache, vision fatigue, or even some form of cancer. Still, appropriate use of time spent interacting with a laptop or smartphone screen can reduce its impact. Read on for a thorough explanation!

 

What Is A LED Light?

LEDs (light-emitting diode) only allow the electrical current to move in a single direction. To be more specific, this lighting technology has two conductive components positioned to contact each other. The only aspect that makes LEDs different from traditional lights is the light generation process, as the traditional ones produce lights by generating heat. 

Nowadays, LED lights are popular thanks to their long lifespan, energy efficiency, low maintenance cost, and safety that traditional lighting can’t be compared to them. 

Yet, have you ever heard that LEDs are harmful to one’s health? Every new product comes with its own set of advantages and disadvantages; LED bulbs are no exception.

Let Best Led Lights show you detailed information on this issue below.

 

Are Our Retinas Being Destroyed By LED Light?

LEDs are well-known for their effective alternatives to traditional light bulbs, as they use 85% less energy and each bulb has an average lifespan of up to 10 years.

However, a study in Spain has shown that this can damage cells in the retina. Some experts even demand LED manufacturers to have a filter fitted in the bulb to ensure safety for human health.

In fact, LED technology has now been widely applied in many aspects of life, not only for residential lighting but also for smartphones, flat-screen televisions, computer screens, etc. So, how does LED light threaten human vision? 

Dr. Celia Sánchez-Ramos of Complutense University in Madrid, Spain, who led the study, explains that: LED chips emit blue light with a high radiation level in the general light spectrum. Whereas the human retina is composed of many light-sensitive tissues, which are responsible for detecting light and allowing us to distinguish each type of light one by one: “The eye does not have the function of looking directly at light – they are designed to detect the light.” 

Dr. continued: Long-term exposure to LED light can negatively affect the human retina. Especially in this day and age, when both children and adults spend a lot of time using smartphones, iPads, and televisions. Our eyes have to open for about 6,000 hours a year and spend most of this time looking at artificial light, which is indeed disturbing for human vision.

From this finding, some experts have called and demanded LED manufacturers to equip a built-in filter to eliminate the blue flicker and be true to the perfect introduced feature of the product as “friendly with users’ health.”

Counterargument From A Leading Eye Specialist

After the findings were published, Bobby Qureshi – a leading ophthalmologist at the London Eye Hospital (UK), pointed out that the test conditions used in this case were false. According to him: “The results of the Madrid study carried out under the condition that a person looks directly at a 100W LED bulb operating at a distance of 30cm for 12 hours a day, which is not what an average person will do”.

Besides, Qureshi also emphasizes that there is no reason to be warned about the blue light from LEDs – because it exists all around us. “If you look at a blue color, it’s the blue of the spectrum,” he says: It stimulates the green-sensitive cells in the retina without damaging the eye.

Nevertheless, Qureshi also said that this study still brings us some values and new knowledge, as it has shown that light from computers, televisions, and mobile devices can be harmful to our eyes and cause symptoms such as headache, dizziness, fatigue if people get exposed for more than 9 hours per day.

 

Should We Continue Using LED Lights?

Our answer is an absolute YES!

LED lights have numerous advantages, which is why millions of people still purchase these products every year! As mentioned above, some incredible benefits of LEDs superior to traditional bulbs are their longevity, eco-friendliness, versatility, and a wider range of colors.

Moreover, LEDs are constantly developing and changing, so today’s LEDs are not the same as the original generation of LEDs, which have been much criticized. The health concerns associated with LED lighting are frequently attributed to these older models or low-quality items.

Thus, we recommend that you work with an LED lighting expert to ensure you get LEDs that are safe for you and your customers/community. Your LEDs should come with the proper correlated color temperature, physical color temperature, kelvins, and other metrics to control blue light. 

It’s also best for you to use high-quality, industry-tested LEDs only. Otherwise, you may risk getting a dangerous LED! Avoid looking at the laptop or smartphone screen for a long time to protect your mental and physical health is a notable point to make!
