Disdiscarded contact lenses will cause environmental pollution

Where did you throw away all those used contact lenses? Studies in the United States have found that random contact lenses can cause plastic particles!

Microplastic refers to the plastic particles with a diameter of less than 5 mm formed after a long time of decomposition in the water environment. It is also known as "PM2.5 in water", which shows its harm. Contact lens materials contain silicone and fluoropolymers, although they are important components to improve the oxygen permeability, but they will form plastic particles and discharge them into the natural environment with sewage. These plastic particles pose a serious threat to aquatic organisms. Because they are difficult to digest after eating, they not only affect the life span of aquatic organisms themselves, but also enter the human food chain, causing far-reaching harm.

In further research, it is also shown that microplastics pollute the water source, and then flow into the soil through irrigation, causing secondary pollution. At the same time, because these particles also with water absorption characteristics, not only cannot completely degraded in the process of sewage treatment, also in sewage contaminated with all kinds of bacteria, microorganisms, dehydration after drying can be broken into many tiny particles, water absorption after restore the volume, the process is difficult to evaluate whether it has the characteristics of absorbing toxic chemicals.

Therefore, contact lenses must not be discarded at will, especially not in the toilet or pool, allowing them to pass through the sewer and cause pollution to water resources. Compared with the related research on plastic products such as plastic bags, takeout boxes and plastic water bottles, we know very little about the impact of contact lenses on the environment, and it is indeed a daily product that is very easy to ignore.

I believe you will be surprised that contact lenses are very humble, but discarded will bring such great harm to the natural environment. According to Chinas garbage classification standards, contact lenses belong to dry garbage, so please throw the used contact lenses into the dry garbage recycling bin! Lets enhance environmental awareness together, with small measures to help the prevention and control of microplastics!
