With advanced smartphone features like night mode, portrait depth, and AR scanning, LiDAR technology is becoming a core part of mobile photography. While it improves accuracy and precision, some users are starting to ask an important question:
Is LiDAR completely safe for daily use — especially around eyes, skin, and sensors?
In this article, we’ll break down the safety concerns around LiDAR sensors in phones, how they function, and whether any real risks exist.
How Does LiDAR Work in Smartphones?
LiDAR (Light Detection and Ranging) works by emitting invisible infrared laser pulses and measuring how long it takes for them to bounce back from surfaces. This allows smartphones to map out the space around them in 3D, which improves focus, AR capabilities, and depth sensing in photography.
You can read more on how it functions in our article on Phone Camera LiDAR Damage, where we explain concerns around hardware and user safety.
Can LiDAR Harm Your Eyes or Skin?
LiDAR used in consumer electronics like smartphones is classified under Class 1 laser safety, which means it's safe under all normal usage conditions — including direct exposure to the eyes. The energy levels are low, pulsed, and tightly regulated by international standards.
Still, manufacturers advise against disassembling or tampering with the hardware where the laser module is located, as internal exposure may bypass safety layers.
Does LiDAR Damage the Phone Camera Over Time?
The LiDAR sensor works alongside the camera — not against it. It doesn’t emit anything harmful to the camera module itself. However, like any advanced feature, it may draw additional battery power and slightly warm the device when used for extended AR scanning or mapping.
Safety Guidelines for Users
-
Avoid pointing the sensor at mirrors or shiny surfaces for long periods. It could affect performance, not safety.
-
Keep your phone updated. Software optimizations improve the safety, stability, and calibration of LiDAR sensors.
-
Don’t attempt hardware repairs. Always seek professional support if your LiDAR system malfunctions.
Conclusion
LiDAR is a safe and powerful tool that enhances mobile photography, AR, and spatial awareness. Concerns about health or hardware damage are mostly myths — as long as devices are used as intended.
So, if you’ve been holding back on using LiDAR on your smartphone, rest assured — it’s built with safety in mind.
