LiDAR Has Something Harmful That Could Damage Your Eyes


Experts claimed that LiDAR could damage the eyes of its users. Previously, Apple confirmed that its latest iPhone 12 flagships offer this feature to enhance its camera quality.

International artist Yvette Mattern shows her stunning laser rainbow projection, Global Rainbow, on March 1, 2012 in Whitley Bay, England. The light installation celebrates the London 2012 Cultural Olympiad in the north-east of England. The Global Rainbow has previously lit up the skies of Germany, France and the United States. The projection will shine along the North Tyneside coastline for 4 days, before moving to other locations in the UK.

Several researchers warn that some kinds of LiDAR could harm the human eyes and cause damage to autonomous cameras that are used for safe operation. Aside from these, this innovation could also damage the cameras used in professional photography, smartphones, and traffic devices. 

Clean Technica reported that LiDAR is considered dangerous because it uses lasers.

The full definition of LiDAR si “Light Detection and Ranging.” This means that it uses a laser to get a picture of its surroundings, which is the same method that radar uses radio waves. 

Right now, various car and smartphone manufacturers use LiDAR technology to improve their cameras. But, some companies don’t use this tech, such as Tesla. 

How LiDAR harms users’ eyes 

Researchers explained that LiDAR has a frequency of 905 nanometers, which is considered too powerful for the human eyes. If the users are exposed to LiDAR regularly, their eyes could be temporarily or permanently damaged, leading to blindness.

At least 219 passengers and crew onboard the Diamond Princess cruise ship have tested positive for COVID-19 making it the biggest centre of the virus outside China. Japan has also so far diagnosed 28 other people with the illness, some of whom are evacuees from Wuhan, and has announced measures to ban entry to foreign travelers.

On the other hand, some types of LiDAR are safe to use. These kinds are those that have a frequency of 1,500 nanometers. Experts explained that this gap makes it hard for LiDAR to penetrate the human eyes. Why? Because eyes are usually opaque to those frequencies. Although these LiDAR models could still damage your eyes, they could not cause blindness.  

Things about LiDAR that are not true 

Right now, this claim is still a speculation. But, it is still a good decision to be extra careful when using your iPhone 12’s LiDAR feature. Here are other beliefs about LiDAR that are considered myths, as reported by Electronic Design

  • LiDAR is expensive
  • Solid-state LiDAR is the best approach because it has no moving parts.
  • LiDAR can’t work in poor weather conditions.
  • LiDAR must operate infrared wavelengths. 
  • LiDAR can only be used for automobiles.
  • Flash LiDAR is the best LiDAR for imaging.
  • LiDAR is a very high-tech solution.
