The optical lens coating is a critical aspect that enhances the performance and durability of lenses. It, therefore, protects your eyes.
What are lens coatings?
A coat is a thin layer of material that is applied to the surface of a lens to reduce reflections, increase light transmission, and protect the lens from scratches and other types of damage.
Some coating types
Various types of coatings are used for different applications, and each type has unique properties that make it suitable for specific uses.
We are going to elaborate on some coatings applied to your lenses that help enhance your vision and as well prolong the life of your lenses.
Anti-Reflective (AR) Coating:
Anti-reflective coating is one of the most common types of coatings used on optical lenses.
This type of coating works by reducing the amount of light that is reflected from the surface of the lens.
This is important because the light that is reflected from the lens can cause glare, reduce the clarity of the image, and make it difficult to see through the lens.
The process of applying an anti-reflective coating to a lens involves depositing a thin layer of material on the surface of the lens. This layer helps to reduce the amount of light that is reflected from the lens, which results in a clearer and brighter image.
Anti-reflective coatings can also help to reduce glare, which can cause eye strain and discomfort.
UV coating is a type of coating that is designed to protect the lens from harmful ultraviolet (UV) rays.
UV rays are a type of light that can cause damage to the lens and the eyes, and they can also cause the lens to fade over time. UV coatings are designed to block these harmful rays, which helps to protect the eye against some diseases caused by UV rays such as cataracts.
UV coatings are typically made from a type of material that absorbs UV rays and prevents them from reaching the lens. This type of coating is particularly useful for people who spend a lot of time outdoors.
Scratch-resistant coating is a type of coating that is designed to protect the lens from scratches and other types of damage. This type of coating is typically made from a hard and durable material, such as diamond-like carbon, which helps to prevent scratches and other types of damage from occurring.
Scratch-resistant coatings are particularly useful for people who use their glasses in harsh environments, where scratches and other types of damage can be a major problem.
This type of coating can also help to improve the overall performance and durability of the lens, which makes it a popular choice for many types of lenses.
Hydrophobic coating is a type of coating that is designed to repel water and other types of liquids.
This type of coating works by using a special type of material that creates a barrier between the lens and the liquid, which helps to prevent water and other liquids from adhering to the surface of the lens.
Hydrophobic coatings are also helpful for people who wear eyeglasses, as they help to prevent rain and other liquids from sticking to the lenses and making them difficult to see.
This type of coating also makes it easier to clean the lens, as any water or other liquids will simply roll off the surface of the lens, making it easier to keep the lens clean and clear.
Color tinted coatings
This coat is applied as a dye in some particular lens types. It acts as a barrier to reduce the intensity of the sunlight on the wearer. This type of coating is available in a range of colors, including gray, brown, green, and blue.
Polarizing coatings are used to reduce glare and improve image contrast. This type of coating works by filtering out light that is polarized in a specific direction, which helps to reduce glare and improve image clarity. Polarizing coatings are particularly useful for outdoor lenses, as they help to reduce glare from surfaces such as water and glass. Polarizing coatings are usually applied to one surface of the lens and can be combined with other coatings such as anti-reflection and scratch-resistant coatings.
The different types of coatings on optical lenses each serve a specific purpose, from reducing reflections and glare to protecting the lens from scratches and moisture.
The type and number of coatings that are used on a lens will depend on its intended application and the conditions under which it will be used.
Understanding the different types of coatings and their uses can help you to choose the right coating add-on for your needs. These facts also help to determine What Your Eyeglasses Say About You. So make it count.
