When it comes to choosing sunglasses, most people focus on the frame style, color, and brand, but the type of lens material used is just as important, if not more so. While there are several lens materials available, including plastic, polycarbonate, and glass, lenses made out of crown glass stand out as the superior choice for those seeking optimal vision.
What is Crown Glass?
Crown glass is a type of optical glass that is made by melting silica and other mineral compounds together at high temperatures. The glass is then cooled slowly, which allows it to solidify without creating any stress or distortion in the material. This process creates a clear, colorless glass that is incredibly dense and has high optical clarity, making it an ideal material for making lenses including for cameras and binoculars.
Advantages of Crown Glass Lenses:
1. Optical Clarity:
Crown glass lenses have a higher refractive index than other lens materials, which means they bend light more efficiently, resulting in sharper and clearer vision. This high optical clarity is due to the uniformity of the material, which prevents any distortions or blurs from affecting your vision.
2. Scratch Resistance:
Crown glass is incredibly dense, which makes it resistant to scratches and other types of damage. This durability ensures that your sunglasses last longer and remain in good condition, providing you with long-term protection against the sun's harmful rays.
3. High-temperature Resistance:
Crown glass lenses can withstand higher temperatures than other lens materials, which means they are less likely to warp or become distorted due to exposure to heat. This resistance is particularly useful for those who spend a lot of time outdoors in hot and sunny environments.
4. Natural Colors:
Unlike other lens materials, crown glass lenses provide a more natural color view. They are free from color distortion, and therefore, objects and colors appear as they would in natural light.
Crown glass lenses can be polarized, which means they can filter out glare from reflective surfaces such as water, snow, and roads. This feature is particularly useful for those who enjoy outdoor activities such as fishing or driving.
Yes, crown glass is an excellent choice for fishing sunglasses as they need to provide clear and accurate vision in a variety of lighting conditions. Crown glass has a high refractive index, which means it bends light more than other types of glass. This can be particularly helpful when fishing in water, as it can help to reduce glare and improve visibility. Crown glass lenses also are highly scratch-resistant and can withstand high temperatures, which is important when in sunny environments. Additionally, the polarizing ability of crown glass lenses can filter out glare from reflective surfaces, such as water, providing an excellent visual experience, making them a top choice for anglers.
Ocean Waves Sunglasses understands the importance of providing its customers with the best possible visual experience. That's why we use lenses made out of crown glass in all of their sunglasses. By choosing crown glass lenses, Ocean Waves offers their customers a superior optical experience that is unmatched by other lens materials.
In addition to using crown glass lenses, we take pride in the fact that we cut our own lenses into the sunglasses in our shop. By doing this, Ocean Waves can ensure that each pair of sunglasses meets their high standards for optical quality and accuracy. This level of control over the lens cutting process also allows us to offer custom lens options to our customers. If a customer has a specific prescription or wants to add special coatings to their lenses, Ocean Waves can accommodate these requests with precision and accuracy.
