what is BPA, and do sunglasses contains BPA?
2022-02-15
BPA stands for bisphenol A, an industrial chemical that has been used to make certain plastics and resins since the 1950s.
BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. They may also be used in other consumer goods.
Bisphenol A was discovered to act as an estrogen in the mid-1930s, and the debate over its use in various fields began.
By 2008, some governments were raising formal questions about its safety in the consumer sector and were taking steps to remove the products from shelves.
In 2010, the FDA raised further concerns based on data collected on multiple fetuses, infants and young children.
In September of that year, Canada became the first country to list it as toxic.
Bisphenol A is banned in the European Union and Canada for the manufacture of baby bottles.
On September 24, 2012, Washington State University and other institutions published their research, published their experimental results in rhesus monkeys, confirmed that BISphenol A can affect the reproductive system of rhesus monkey female offspring, resulting in egg chromosome abnormalities.
What Makes BPA Harmful?
Some research shows that BPA can be harmful once it seeps into your food or beverages. For example, containers with this element can mix into your food without you even noticing it.
This exposure may compromise your health and affect children’s behavior. Aside from what we’ve mentioned, here are other problems with high exposure to BPA.
Brain problems
Prostate complications
Increased blood pressure
But, it is not the case with sunglasses. Nobody eats it. Plus, manufacturers use a minimal amount of this element.
Thus, it won’t pose such a threat unless the producer used too much BPA. It may happen in sporadic cases, though.
It’s because high-grade eyewear manufacturers follow safety standards to comply with strict protocols. Otherwise, they won’t pass Either EU or FDA standards. European Union and Food and Drug Administration are responsible for regulating items in European and US countries.
Some countries may have banned BPA in items like kids’ bottles, but it has no same effects on sunglasses. Thus, it leads us to this next question.
Why Do Manufacturers Still Use Polycarbonate?
There are reasons why manufacturers use polycarbonate materials on sunglasses.
High resistance
100% ultraviolet protection
Lightweight and thin
Scratch-free
Combine these features in one pair of sunnies. As a result, you’ll get durable and the ultimate protection against the sun.
With polycarbonate lenses, you can get more resistance from breaking. It’s true, especially if you have clumsy hands. Think of its lenses like those small red ants – tough but lightweight.
Compared to plastic or glass lenses, polycarbonate also has the highest UV safety.
Most of all, you can wear it without any hassle. You won’t have to worry about feeling heavy on your nose or around your ears.
Do you drop objects often? Polycarbonate ensures scratch-free features while correcting your vision.
See? Polycarbonate is not bad at all. California’s government wanted to inform its citizens about such chemicals. Prop 65 also gives them choices if the people would trust or use an item with BPA or not.
Is It Safe To Wear Sunglasses With BPA?
You have nothing to worry about wearing sunglasses with BPA.
First of all, you should note that polycarbonate lenses are inside the frame of the eyewear. It means that you will have no direct virtual contact with your face.
But, it may not be the case if you bought a pair of rimless frames as it will sit on your cheeks.
Second, sunnies with BPA have been common for decades. It has no proven or any direct correlation with compromising anyone’s health. There’s still not enough proof indicating how much exposure to BPA can you get from skin contact.
It becomes a problem if someone is in the habit of chewing or licking the plastic frames of the sunglasses. This problem is common for infants who are curious about things.
Aside from it’s an unhygienic habit, it’s when things can get at risk. Experts believe that most exposure to BPA happens through ingestion. So, any exposure through skin contact is insignificant.
Still, it is vital that you buy a pair of sunglasses only from reliable producers. Most experienced sunglasses makers only use minimal amounts of BPA.
Thus, polycarbonate eyewear is safe to wear. Manufacturers spent years of research on making each pair safe and efficient to use.
