Greater Protection: Polycarbonate lenses do not break or shatter easily into harmful pieces on impact. Their high impact resistance provides greater protection from eye damage or injury due to broken or shattered eyeglass lenses.
Are polycarbonate lenses good for eyes?
Thinner and lighter than plastic, polycarbonate (impact-resistant) lenses are shatter-proof and provide 100% UV protection, making them the optimal choice for kids and active adults. They’re also ideal for strong prescriptions since they do not add thickness when correcting vision, minimizing any distortion.
Are polycarbonate lenses bad?
It also has good UV protection and a higher refractive index than CR39. The disadvantages of polycarbonate lenses include the fact that their abrasion resistance is poor, but when an anti scratch coating is added to this the impact resistance is reduced slightly. These types of lenses cannot be tinted easily.
Are polycarbonate glasses safe?
Polycarbonate eyeglass lenses are 10 times more impact-resistant than glass or regular plastic lenses, and they exceed the FDA’s impact resistance requirements by more than 40 times. …
Are polycarbonate lenses better than glass?
Polycarbonate lenses are highly resistant to impact, won’t shatter, and are 10 times stronger than glass or standard plastic, making them ideal for children, safety lenses, and physical activity. Lightweight and thinner than glass lenses, polycarbonate is more comfortable to wear for long periods of time.
Is it worth getting polycarbonate lenses?
Polycarbonates lenses are worth it. They’re durable and impact-resistant, lightweight and thin, and even offer extremely effective UV protection. … Considering their price and the many pros that come with polycarbonate lenses, they are definitely worth it in both the long run and short term.
Which lens is best for eyes?
|Lens material||Refractive index||Salient features of the lens|
|Polycarbonate||1.586||Block 100 percent UV. Light-weight Impact resistant|
|CR 39||1.498||Excellent optics, low cost Thick lenses|
|Crown glass||1.523||Excellent optics, low cost Thick lenses, breakable|
Is polycarbonate better than plastic?
Polycarbonate sheets have been proven to be superior to other plastic materials used in similar applications in almost every area of comparison. … Polycarbonate provides excellent impact and weather resistance, compared to the average resistance in case of plastics.
Can you remove scratches from polycarbonate glasses?
Step 2: Squeeze a dime sized amount of regular toothpaste onto a clean, soft, cotton cloth. Rub the toothpaste onto the scratched surface of the polycarbonate lens in a circular motion for ten to twenty seconds. … Immediately wipe the wax off with a clean, soft, cotton cloth.
What are the most scratch resistant lenses?
Glass lenses provide excellent optics, the most scratch resistant lens material and blocks UV light. However, glass lenses are heavy, thick and dangerous if broken and cannot be used in certain frame styles. Some glass is available with a refractive index as high as 1.8 and 1.9.
