Crystal lenses VS polycarbonate

Welcome to our ReplacementLenses.net blog! In this post we are going to talk about one of the most important decisions when buying new glasses: should you opt for glass or polycarbonate lenses? Both have their advantages and disadvantages, and it’s important to know them in order to make an informed decision. Read on to learn more about the comparison between crystal / glass vs. polycarbonate (plastic) lenses.

Although glass is the traditional material that has been used for years to make high-quality lenses, more and more people are opting for polycarbonate lenses because of their advantages. However, each has its own advantages and disadvantages, and in this post we’ll help you understand them so you can make an informed decision when choosing your next pair of glasses.

Glass lenses

Glass lenses have several advantages, such as superior optical quality, which means they provide sharper and clearer vision. In addition, they are highly scratch-resistant and offer exceptional durability. However, glass lenses also have some drawbacks, such as their weight and fragility, which can make them less comfortable to wear and more prone to break if dropped or knocked. They can also be more expensive than polycarbonate lenses. It is important to note that although glass lenses have certain advantages, their use has been declining in recent years. This is because polycarbonate lenses and other plastic materials have become increasingly popular.

Polycarbonate lenses

Polycarbonate lenses are a popular choice for eyewear, especially for those looking for lightweight, durable lenses. Polycarbonate is a type of plastic that is used in a variety of applications, from motorcycle helmet visors to computer and cell phone screens. Although not as scratch-resistant as glass lenses, polycarbonate lenses are less likely to break in falls, making them an ideal choice for sports and outdoor activities. In addition, polycarbonate lenses tend to be less expensive than glass lenses, making them more affordable for most people. It is currently the most widely used material for spectacle lenses because of all the advantages mentioned above.

Which one is better?

The outcome of polycarbonate vs. glass is up to you to decide. It is important to note that there is no single answer to the question of which is better, as both options have their own advantages and disadvantages. Glass lenses may offer greater optical clarity and scratch resistance, but they are heavier and can break more easily. On the other hand, polycarbonate lenses are lighter and more impact resistant, but can scratch more easily and may exhibit optical distortion in some cases.

The choice between glass and polycarbonate lenses will depend on you and your circumstances, evaluate the characteristics of each material and choose the option that fits your needs.

      Lenses cannot be polished because it would change the optical geometry and you would not see well through them.
