Glasses Nosepiece Turns Green

Glasses Nosepiece Turns Green


Many people will suddenly notice that the nosepiece of their eyeglasses has turned green after using them for a period of time. Some people will choose to ignore it and continue to use their eyeglasses. Others will think that the glasses are moldy and need to replace them with a new one. So, does this situation need to be brought to our attention or not?


What is the Green Dirt on the Nose Bridge?

Why do Eyeglass Nosepieces Turn Green?


The nosepiece is an important part of the eyewear frame, which plays a supporting role, and most of them are made of PVC. The green dirt on the nose rest is produced by the oxidation of your sweat and the metal material. Glasses are generally worn for a period of time, the nosepiece and the inner groove of the nosepiece will be prone to rust and turn green.


Is the Patina on the Nosepiece Harmful?


Firstly, patina looks unsightly and dirty. Secondly, pure patina contains bacteria, which can affect the skin, but is not particularly harmful. However, if it contains other substances, it may be hard to determine. Qualified eyeglasses are made of alloys that do not exceed the standard for lead and nickel, but low-end cheap eyeglasses may contain environmentally friendly alloys. Under this situation, then it will be harmful to the human body.

1. Unscrew the small screw and wipe it carefully with a soft paper towel.


2. Wipe your eyeglasses with 75% medical alcohol and an eyewear cloth.

 


3. Some people say you can use white vinegar to scrub it clean. However, if you use acid or alkaline substances, the patina will appear faster and more often.


4 . Go to an optical store regularly for professional care. Eyeglass stores can use ultrasonic cleaners for cleaning, which is usually free of charge. Be sure to screw all the screws again after ultrasonic cleaning, because ultrasonic shock can loosen the screws.


5. Go directly to the optician to change a nosepiece, which is usually also free of charge.


6. After cleaning, it is advisable for you to apply some oily substance (such as nail polish) for protection, which can prevent the reappearance of patina.


How to Avoid the Patina on the Nosepiece?


1. When choosing your eyewear frame, it is essential to pay attention to the material of the eyewear frame. If you choose a plastic eyewear frame without a metal nosepiece, you can avoid this problem.


2. If you want to choose a metal eyewear frame with a metal nosepiece, it is recommended to choose a titanium eyewear frame and avoid a copper alloy eyewear frame. Because the copper alloy eyewear frame is inevitable to produce green rust for a long time.


3. Periodically you can use ultrasonic cleaning, but it is not recommended to clean too often.
