How to prevent laser damage to eyes?

To prevent laser damage to the eyes, measures need to be taken from multiple aspects.

 First, in a working environment where laser exposure is possible, safety regulations and operating procedures must be strictly followed to ensure the correct use of laser equipment. For example, operators should receive professional training to understand the characteristics and potential risks of lasers. 

Secondly, set up obvious warning signs to remind irrelevant personnel to stay away from laser radiation areas. At the same time, equip appropriate personal protective equipment, such as protective glasses, which can effectively block laser radiation. 

In addition, laser equipment should be inspected and maintained regularly to ensure its stable performance and no accidental laser leakage. 

Laser equipment in daily life, such as laser pens, should be properly kept to avoid children's contact and improper use.
