I have been wearing glasses for more than ten years. When I take off my glasses at intervals every day, I will find that the middle part of the lens is very mushy and dirty. However, many other people say that this is not the case, and they are very troubled.
First: the film layer of the lens.
The surface of the lens will be coated with anti-fouling and dust-proof. If the lens is easy to get dirty, it may be that the surface of your lens lacks anti-fouling film and anti-static film layer, so that dust is easily adsorbed on the surface of the lens.
Second: the adjustment of the lens.
For example, the distance between the glasses and the eyes. If the distance between the glasses and the eyes is too close and the cheekbones are too high, it is possible that the lower edge of the lens is attached to the skin surface or your eyelashes are too long and the eyelashes will brush against the lens when you blink.
Third: Personal habits.
After wearing glasses, we will unconsciously push the glasses or lift the glasses. When doing the action of lifting the glasses, we may touch the lens of the glasses and cause fingerprints, and dust will be absorbed if not cleaned in time.
Many friends who wear glasses, when cleaning their glasses, just wipe them with a glasses cloth. In fact, this does not have a good cleaning effect on the glasses, although the glasses cloth feels soft to the touch. Yes, but the material of the cloth is not fine enough, and after repeated use, there are many tiny dust particles on the cloth. If you directly wipe the lens with a spectacle cloth, it is equivalent to rubbing the lens with many fine particles. Over time, the lens will naturally become dirty.
The real function of the glasses cloth is not to wipe the glasses, but to wrap the glasses. Wrap the glasses with a cloth and put them in the glasses case, which can prevent the lens from rubbing against the glasses case and damage the lens.
So how to clean it without damaging the lens? Share with you a few small ways to clean your glasses.
It is a correct way to use detergent to clean the glasses, or use a neutral hand sanitizer, apply the detergent/hand sanitizer evenly on the lens, then rinse with water, and finally use a clean paper towel to absorb the water droplets, But don't wipe back and forth. You can also use alcohol-free professional lens cleaning paper, which is not only easy to carry, but also comes with a cleaning agent that can effectively dissolve oil stains for easy cleaning.
Never use a dry cloth to rub the lens vigorously in circles, otherwise the lens will be easily worn and its lifespan will be greatly shortened.
All of the above are for the cleaning of the lenses. For places that are difficult to clean, such as the gaps between the nose pads and the frame, you can go to the optical shop to use an ultrasonic cleaner to clean them. Because the nose pads and crevices are often exposed to sweat, if they are not cleaned for a long time, the frame may rust, so the cleaning of these two positions cannot be ignored.
