Understanding CR39 Lenses with AR Coating: A Comprehensive Guide
When it comes to selecting the right lenses for your eyewear, the choice can be quite overwhelming. One term that often catches the eye is “CR39 lenses with AR coating.” But what exactly does this mean, and why should you consider it? Let’s delve into the details to help you make an informed decision.
What are CR39 Lenses?
CR39 lenses, also known as polycarbonate lenses, are a popular choice for eyewear due to their lightweight, impact-resistant, and shatterproof properties. Made from a plastic material called CR-39, these lenses offer a high level of clarity and are suitable for a wide range of prescriptions.
Why Choose CR39 Lenses with AR Coating?
While CR39 lenses are already a great choice, adding an AR coating takes the benefits to a whole new level. Here’s why you should consider CR39 lenses with AR coating:
| Benefits of AR Coating | Description |
|---|---|
| Anti-reflective (AR) Properties | AR coating reduces glare and reflections on the lens surface, improving visibility and comfort, especially in low-light conditions. |
| Water and Oil Repellent | The coating makes the lenses easier to clean and more resistant to smudges, making them a practical choice for everyday use. |
| Scratch Resistance | AR coating can also provide an additional layer of protection against scratches, extending the lifespan of your lenses. |
| Weight Reduction | While the weight of the lenses is minimal, the AR coating can slightly increase the weight. However, this is a small trade-off for the benefits it offers. |
As you can see, the benefits of AR coating are substantial, making CR39 lenses with AR coating an excellent choice for those who want to enhance their vision and comfort.
How is AR Coating Applied?
AR coating is applied to the lenses using a specialized process that involves several steps:
-
The lens is cleaned and polished to ensure a smooth surface.
-
A chemical solution is applied to the lens, which helps the AR coating adhere to the surface.
-
The lens is then baked at a high temperature to cure the coating.
-
The lens is polished again to remove any imperfections and ensure a clear, smooth finish.
This process ensures that the AR coating is durable and long-lasting, providing you with the benefits for years to come.
Choosing the Right AR Coating
Not all AR coatings are created equal. When selecting CR39 lenses with AR coating, consider the following factors:
-
Quality: Look for a reputable manufacturer that uses high-quality materials and processes.
-
Thickness: Thicker coatings may offer better protection but can also increase the weight of the lenses.
-
Color: Some AR coatings may have a slight tint, which can affect the appearance of the lenses.
-
Price: While AR coating adds to the cost, it’s important to find a balance between quality and price.
By considering these factors, you can choose the right AR coating for your CR39 lenses, ensuring you get the most out of your eyewear.
Conclusion
CR39 lenses with AR coating offer a combination of clarity, comfort, and durability that makes them an excellent choice for eyewear. By understanding the benefits of AR coating and how it’s applied, you can make an informed decision when selecting your next pair of glasses. So, the next time you’re in the market for new lenses, don’t forget to consider CR39 lenses with AR coating for an enhanced visual experience.
