Researchers Find LED Lights Could Cause ‘Irreversible’ Damage To Our Eyes

LED technology has been hailed by many as the next-gen tech that we can expect in our lights and displays. There are benefits to using LEDs, such as how it consumes less power than regular light bulbs, and for our displays, the lower power consumption also means that our phones can last longer.

However, it seems that LED lights might not be as good as we thought, at least for our health. According to a new report from the French Agency for Food, Environment and Occupational Health and Safety (ANSES), they have expressed concern on how our constant exposure to LED lights could cause “irreversible” damage to our eyes.

The report published by the agency talks about how LED could be potentially “photo-toxic” which means that it can lead to the loss of retinal cells and also diminished sharpness of vision. They also talk about the high-intensity exposure to LED light, as well as “chronic exposure” from lower-intensity sources, which according to report, can “accelerate the ageing of retinal tissue, contributing to a decline in visual acuity and certain degenerative diseases such as age-related macular degeneration.”

This is not the first time that lights from our devices have been found to potentially contribute to vision-related problems. Previously, it was said that the blue light emitted from our smartphones can not only accelerate blindness ^(, but can also mess up our sleep patterns.

Researchers 3D Print A Heart Using Patient’s Own Cells

Curing heart disease can be tricky because in some cases, the only way for a person to survive would be to get a heart transplant. Unfortunately, finding a suitable donor is difficult, not to mention there is a waiting list as well, and there are also complications with regards to the body accepting the new organ.

However, there is some good news on that front because thanks to researchers at the Tel Aviv University, they have managed to 3D print a heart which paves the way for the future in combating heart disease. The 3D printed heart was also made using the patient’s own cells, meaning that it is 100% compatible and will not be rejected by the patient’s body.

This was done by taking the fatty tissue from a patient, separating the cellular and non-cellular components, and then “reprogrammed” to become stem cells which later turned into heart cells. According to the study’s press release, “Patients will no longer have to wait for transplants or take medications to prevent their rejection. Instead, the needed organs will be printed, fully personalized for every patient.”

Before you get too excited, know that at the moment this is still very early in development. The researchers have only managed to 3D print a heart that measures 2.5 centimeters, making it too small to be used by humans. It is expected that for a full-sized human heart, it would require billions of cells and could potentially take an entire day to print, but that doesn’t mean that the project doesn’t have potential.

According to Tal Dvir, the professor who directed the project, he suggests that perhaps this process could be used to print patches of the heart and just replace the diseased areas.
