People who wear cheap eyeglasses near me encounter various problems in their daily lives, such as not being able to wipe their glasses clean when they get wet on rainy days, going out for a day and returning home with gray glasses, and I don't know why the lenses are always scarred.

These situations are all related to the film layer of the eyeglass lens. A good film layer can improve the performance of the lens, making it more wear-resistant, waterproof, and dustproof. The various film layers of eyeglass online lenses play different roles in daily life.

On rainy days, when going out, my cheapest eyeglasses online are always wet by the rain, and I accidentally get oil stains while eating. Whether I use a glasses cloth or a tissue to wipe them off, I always feel that the glasses are still foggy and cannot be seen clearly, which seriously affects the visual experience.

At this point, the waterproof film layer comes into play. A waterproof film is a very thin top film that can make the surface of the lens hydrophobic. Oil and water droplets are difficult to stay on the surface of the lens and automatically fall off, thus playing a waterproof and anti-fouling effect. Its principle is the same as the rolling of water droplets on lotus leaves.

The essence of waterproof film is to reduce the contact area between water and oil and the lens, making it difficult for oil and water droplets to adhere to the surface of the lens. Knowing the characteristics of lenses, I believe your newly matched glasses can last longer! Glasses are a rather delicate commodity. It is afraid of pressure, falling, breaking, high temperature, and corrosive liquids.
