In the previous article, we discussed “Should you wear sunglasses in the winter?”. In this article, let’s talk about “Can you use rubbing alcohol to clean glasses?”.
Medical alcohol can't be used to wipe glasses, and it will damage the glasses. We know that although the general medical alcohol is only about 75%, it is still corrosive.
Can't Use Alcohol To Clean Glasses
Generally speaking, alcohol is not suitable for cleaning resin lenses. Resin lenses are relatively soft and are usually coated with a film. It not only improves the hardness of the lens, but also has more other functions. The lens film is not suitable for cleaning with harsh cleaning agents. As we all know, alcohol has a certain stimulating effect, so it is harmful to the film of the lens.(https://www.koalaeye.com/collections/eyeglasses)
The Irritation Of Alcohol
The stimulus effect of alcohol will damage the coating of the lens. If the coating of the lens is destroyed, the transmittance of the lens will decrease and the clarity of the lens will decrease. In addition, if the film layer of the lens is damaged, the scratch resistance and anti-reflective properties of the lens will decrease. Especially if the film layer of the lens is damaged severely, the lens is easily scratched, which directly affects the vision. Therefore, when cleaning the lens, you must be careful not to use irritating cleaning.
Clean Glasses Properly
If the glasses are dirty, don't just wipe them with other cloth. If you use some hard cloth to wipe, it is easy to cause scratches in the lens. Generally speaking, the following cleaning methods are all feasible.
1. Use neutral or alkaline cleaning agent. Remember, toothpaste cannot be used as a substitute for the cleaning agent for spectacle lenses. General optical shops also sell lens cleaners in small bottles, which are easy to carry.
2. Go to the optical shop for professional ultrasonic cleaning. General optical shops provide free cleaning services. The ultrasonic cleaning machine can fully clean every gap and groove of the glasses.
3. Rinse the lens with tap water. Hold the frame in one hand and the cleaner in the other hand. Rub it slowly against the lens, and then rinse it off with clean water. Then wipe it with a glasses cloth or let it dry naturally.
In addition to the glasses cannot be cleaned with alcohol, you should also pay attention to their placement for daily maintenance. Try to avoid putting it under high temperature, and avoid oily, smoke, etc. If you don't use them, put them in the glasses case.
