Introduction
Infrared radiation can harm the eyes. Due to its strong penetrating power, when infrared rays shine on the eyes, they can directly reach the retina and damage retinal structures, potentially leading to atrophy of the macular region. Additionally, infrared radiation produces a significant heating effect on human tissues. Prolonged exposure causes the eye to absorb excessive energy, which may cloud the lens and negatively affect eye health.
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.
