Cost Analysis Of Plastic Lenses: How Much Do They Cost?

Plastic lenses are generally made from a strong material called CR-39, but are also available in a range of hi-index lenses, which are thinner and lighter. They are very light and comfortable to wear, and are highly resistant. They are also much less expensive than other options, such as polycarbonate. However, compared to natural glass, plastics have a low scratch resistance and are more sensitive, requiring additional maintenance.

Plastic lenses are cheaper than polycarbonate lenses

Plastic lenses are much cheaper than polycarbonate lenses. They are also less expensive than glass lenses. In addition to being a more affordable option, plastic lenses are lightweight, impact-resistant, and provide better optical clarity. This makes them ideal for active individuals, such as children and athletes.

Plastic lenses are made from a strong material called CR-39 and are available in a range of hi-index lenses, which are thinner and lighter than standard lenses. They are very light and comfortable to wear, and they offer better protection against flying sparks from activities such as welding and grinding work.

However, it's important to note that plastic lenses have a lower scratch resistance compared to natural glass. As a result, they may require additional maintenance and care to ensure their longevity.

When choosing between different types of lenses, it's essential to consider factors such as cost, quality, and your specific needs. Glass lenses, for example, are better suited for severe vision correction and multifocal needs due to their higher refractive index. On the other hand, plastic lenses excel in terms of weight and impact resistance, making them a popular choice for those with active lifestyles.

Plastic lenses are lightweight

Plastic lenses are generally made from a strong material called CR-39, but are also available in a range of hi-index lenses, which are thinner and lighter. While most people prefer the newer plastic lenses, there are still a number of people who continue to prefer glass.

The greater the refractive index range of the eyeglass lens material, the thinner the finished glass. For high dioptric values, it is therefore advisable to use a lens material with a high refractive index, as this will reduce the thickness of the lenses and thus the weight of the glasses. Natural glass has a clear advantage here: its refractive index range extends from 1.5 to 1.9, while the refractive index range of organic glass (plastic) is only 1.5 to 1.74.

Plastic lenses have a higher Abbe value than polycarbonate, so they offer better optical clarity. They are also much less expensive than the other options.

Plastic lenses are impact-resistant

Plastic lenses are generally made from a strong material called CR-39, but they are also available in a range of hi-index lenses, which are thinner and lighter. They are very light and therefore comfortable to wear. They are also highly resistant and impact-resistant, making them ideal for active individuals like children and athletes. In that respect, they outperform glass up to 100 times, depending on the type of plastic used. Moreover, they provide better protection against flying sparks (for example from fireworks, campfires, welding and grinding work) and cannot splinter – a significant safety benefit in many everyday situations.

The greater the refractive index range (also called the refraction index) of the eyeglass lens material, the thinner the finished glass. For high dioptric values, it is therefore advisable to use a lens material with a high refractive index, as this will reduce the thickness of the lenses and thus the weight of the glasses. For example, a lens with a refraction index of 1.6 is always thinner than one with a refraction index of 1.5 for an identical dioptric value. Natural glass has a clear advantage here: its refractive index range extends from 1.5 to 1.9, while the refractive index range of organic glass (plastic) is only 1.5 to 1.74. Natural glass also has a greater density than plastic.

Plastic lenses have a higher Abbe value than polycarbonate. Therefore, plastic offers better optical clarity. Additionally, plastic lenses are much less expensive than the other options. However, compared to natural glass, plastics have low scratch resistance. As a result, they are more sensitive and require additional maintenance.

The cost of plastic lenses varies depending on the prescription and the seller. However, plastic lenses are generally much less expensive than other options. They are also lightweight, impact-resistant, and highly resistant to flying sparks, making them ideal for sports and children's glasses.

While plastic lenses are generally made from a strong material called CR-39, they are also available in a range of high-index lenses, which are thinner and lighter. The refractive index range of plastic lenses is 1.5 to 1.74, while the refractive index range of natural glass is 1.5 to 1.9.
