Can infrared radiation harm the eyes?
In general, infrared radiation can harm the eyes. The detailed explanation is as follows:
Infrared radiation is an invisible electromagnetic wave with wavelengths between radio waves and visible light, typically ranging from 0.75 to 1000 μm. Due to its strong penetrating ability, when infrared radiation reaches the eye, it can directly reach the retina and damage retinal structures, potentially leading to macular atrophy. Additionally, infrared radiation produces a significant heating effect on human tissues. Prolonged exposure may cause the eye to absorb excessive energy, resulting in clouding of the lens and reduced transparency, which negatively affects eye health.
If exposure to infrared radiation is unavoidable due to occupational requirements, it is advisable to wear protective eyewear to minimize and prevent eye damage. If any eye discomfort occurs, prompt medical attention is necessary.
