What are the types of membranes on glasses?

The eye is a very important visual organ for human beings.

The structure is very sophisticated and complex.

There are various "membranes" in the human eye, and each membrane has its own unique role.

The importance of "membranes" to the eyes can be seen.

But not only eyes, but also glasses have "membranes", and there are many types.

The "membrane" of glasses is not so much a membrane as a special microstructure in essence.

It is only because of the continuous structure and the thickness (molecular level) that it is called a "membrane".

Different spectacle "membranes", with different microscopic molecular structures,

Brings different protections.

What does lens coating mean? Anti-fog filmAnti-fog film is also called hydrophilic nano film layer,

The ability to overcome the surface tension of water droplets greatly reduces the chance of fogging formation.

When lenses with this coating are used in conjunction with a dedicated lens cloth,

A wipe can have a good and long-lasting anti-fog effect.

To put it simply, the anti-fog film does not repel the water droplets, but arranges the water mist molecules on the surface of the lens more tightly and smoothly.

A "water film" with good light transmission is formed.

Waterproof filmThe waterproof film is a very thin top film that makes the surface of the lens hydrophobic.

It is difficult for oil and water droplets to stay on the surface of the lens and fall off automatically, so it has a waterproof and anti-fouling effect.

The principle is the same as the rolling of water droplets on a lotus leaf.

The surface of the waterproof membrane is actually a small protrusion, and the gap between the protrusions is too small.

is so small that when water molecules fall on it, they cannot be "embedded" in the voids.

I had to roll down under gravity.

The essence of the waterproof membrane is to reduce the contact area between water and oil and the lens,

This makes it difficult for oil and water droplets to adhere to the surface of the lens.

The dust-proof function of the dust-proof "film" lens, thanks to the use of i-technology,

This makes the molecular structure on the surface of the lens more dense, and the dust cannot "get in".

The principle is actually similar to that of a waterproofing membrane.

Anti-reflective filmAnti-reflective film, also known as anti-reflective film, is to coat the front surface of the lens with multiple layers of transparent materials with different refractive indices and different thicknesses.

The principle of light interference is used to reduce the excess reflected light on the surface of the lens.

When an anti-reflective coating is added to the lens, the permeability to light increases.

The wearer will experience less glare and more realistic and brighter vision.

In order to improve the wear resistance of lenses, it is necessary to use a hardening fluid containing organic matrix and inorganic ultrafine particles.

A hard coating is applied to the surface of the lens to give the surface of the lens both toughness and hardness.

This film is an abrasion-resistant film that reduces scratch damage.

Anti-ultraviolet & anti-blue light film medium and long wave ultraviolet rays in sunlight,

It is very harmful to human eyes and skin.

Independent studies have shown that 50% of the ultraviolet rays that enter the human eye come from reflections from the surface behind the lenses.

It has also been found that blue-violet light in the wavelength range of 415-455 nanometers,

It is most harmful to retinal cells.

In order to cope with the damage of ultraviolet and blue-violet light to the human eye, a technology called "broad-spectrum coating" came into being.

The biggest advantage of this "membrane" structure is that it can intelligently filter harmful light.

through normal light.

It is precisely because of these glasses membranes with different functions that our eyes are protected accordingly.

When choosing glasses, you must pay more attention to the membrane on each pair of eyes.

Choose the membrane we need for our eyes so that they can be better protected.
