What are the precautions when wearing safety glasses? Here are the precautions for wearing safety glasses, covering key points from preparation, correct usage, maintenance, to special scenarios. Follow these guidelines to ensure optimal eye protection.

Safety glasses are specialized eye protectors designed to shield the eyes from physical, chemical, or environmental hazards. They differ from regular eyewear by meeting specific safety standards (e.g., ANSI Z87.1 in the U.S., EN 166 in Europe) to ensure effective protection.

UV400 protection is non-negotiable for eye health, as it blocks all harmful UVA and UVB rays that cause long-term damage. When shopping for sunglasses or prescription eyewear, prioritize lenses with clear UV400 certification and avoid products with vague labeling.

There are many types of lenses, so the materials used to make them are naturally different. In this issue, Jiayu Optical Lens will briefly introduce various types of lens materials for everyone.

Many people use a pair of sunglasses for many years. In fact, sunglasses also have a shelf life, which is related to the wearing time, lens material, wearing habits, regional sunlight, and so on. Generally speaking, the best usage period for sunglasses is about two years, and it is best to replace them with a new pair after that.

Wearing sunglasses with proper UV protection is indeed an important measure to **reduce the risk** of developing cataracts, though it does not completely prevent them.
