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.

Can I use my prescription for contact lenses?
You cannot and should not use your glasses prescription to calculate your contact lens prescription. It's important to note that not everyone who needs glasses can wear contact lenses, and it's important to check them separately. Some people have sensitive corneas or other eye complications and never get used to wearing contact lenses.
Adjustment of the upper and lower position of the nose pad
The nose pad can be pulled up and down with the pliers of the nose pad to achieve the purpose. You can use needle-nose pliers to clamp on the nose pad and apply torque in a certain direction to change the upper and lower position of the nose pad. When applying the torque, the nose pad can be pressed down or pulled up by the pliers to change the position of the deformation of the bracket, to prevent repeated deformation and fracture near the solder joint.
The price of new lenses
The price of the new lenses depends on several factors, including if you have vision insurance. Another aspect to think about is that if your lenses need an anti-glare solution. If so, the lenses may be much more expensive. If you need eye exams and special lenses, the cost can be quite high. Scratched lenses are easier to repair. If you want your scratched lenses repaired by a professional, most opticians can pay very little.
The Disadvantages of Trivex Lenses
In this section, we will show you the disadvantages of Trivex lenses.

Is it necessary to repair the glasses that are badly damaged?
If your glasses are badly damaged, think about getting a new pair. Maintenance is maintenance, not a replacement, so there are some traces of maintenance. The repair cost is far more than or can buy a new pair of glasses, so there is no need to repair them. For the kind of alloy that's used for cheap glasses and the kind of alloy that's used for high-end glasses, the texture of the welding is so different. There are differences in intensity. In order to make the cheap glasses strong after welding, it will definitely increase the welding marks (solder repair, etc.), so the marks will be obvious.
