What Is Plastic Lens?

In the above part, we have introduced what polycarbonate lenses are. In this section, we will show you what the plastic lens is.

The plastic lens was first introduced in 1947. Since then, plastic has become a popular and widely used material for making eyeglasses lenses. Since the introduction and use of plastic lenses, it has sealed its mark as the most preferred choice in the optical industry.

Plastic lenses are light. With this feature, plastic lenses are popular because they will not be heavy inside the glasses frame and permit for an easy fit in any type of glasses frame. In addition, plastic glasses are cheap and easy to obtain in desired amounts. So, they are affordable for most people. Plastic lenses are very durable. So, they do not shatter easily on impact which makes it a great choice for individuals who are active or tend to drop their glasses often.

However, compared with other lens materials, plastic lenses are usually thick due to their low index of refraction. The soft feature of plastic glasses makes them susceptible to scratching from a sharp object and why scratch-resistant coating is applied to form an additional protective layer. Plastic lenses do not provide ultraviolet protection.


Pure titanium has special current characteristics

Pure titanium can guide electron fluctuations to produce ions, causing the current to tend to ionize. The positive and negative ions can adjust the adverse effects of electromagnetic waves caused by the body's biological current disorder and have a great health care effect on the human body in order to avoid fatigue, muscle stiffness, soreness, and other symptoms or problems.

The heart-shaped face is also a common face shape in daily life. This face shape is somewhat similar to the inverted triangle face shape. Generally, the chin is a relatively sharp face shape. For this type of face, the most important thing is to modify the cheekbones above the nose to highlight the slenderness of the chin. Therefore, it is better to wear a pair of angular glasses, which can effectively modify the facial lines and look more perfect.

Can clear lenses be polarized?

At present, there are no clear polarized lenses. A polarized lens is a thin film vertically arranged with silicon crystal coating placed inside the lens, just like a shutter, which covers the parallel light and only allows the vertical light to pass through. In this way, the glare from all directions can be eliminated, so it is clear and comfortable to wear. Transparent polyamide, the material of nylon lens, is a new variety of polyamide. The material of the nylon lens is mainly transparent polyamide. Due to the effect of the light filter, only light from a specific direction is allowed to pass through the lens, which filters the dazzling light from the sun on the water, land, or snow very well. It can not only make the landscape soft, clear, and natural but protect the eyes to a certain extent.
