Glasses are no longer just a functional accessory for better vision. They have become an integral part of our style statement. They not only help us see better but also make us look better. However, glasses also come with their own set of challenges, such as glare and reflections that can cause discomfort and reduce visibility.
This is where Anti Reflective (AR) coating on glasses comes in. In this article, we will discuss some important facts about AR coating on glasses that everyone must know.
What is Anti Reflective (AR) Coating?
AR coating is a thin layer of metal oxide applied to the surface of glasses to reduce the amount of glare and reflections. It allows more light to pass through the lenses, which in turn makes the vision clearer and reduces eye strain.
AR coating is particularly helpful for people who spend a lot of time in front of computer screens, drive at night, or work under fluorescent lights.
Benefits of Anti Reflective (AR) Coating
- Reduced glare and reflections: AR coating reduces glare and reflections, making it easier to see and reducing eye strain.
- Improved night vision: AR coating can improve night vision by reducing the glare from headlights and streetlights.
- Enhanced appearance: AR coating makes glasses look more attractive by reducing the reflections on the lenses.
- Easy to clean: AR coating makes it easier to clean glasses as it reduces the amount of dust, fingerprints, and smudges on the lenses.
- Increased durability: AR coating protects the lenses from scratches and other damage, making them last longer.
How is AR Coating Applied?
AR coating is applied to the lenses using a vacuum deposition process. The lenses are placed in a vacuum chamber, and a thin layer of metal oxide is applied to the surface of the lenses. The process takes about 10-15 minutes, and the lenses are then cured in an oven to ensure that the coating adheres properly.
Replacement Lenses and AR Coating
If you need replacement lenses for your glasses, it is important to know that not all replacement lenses come with AR coating. While some replacement lenses come with AR coating pre-applied, others require the coating to be applied separately.
It is important to check with your eyewear provider to see if the replacement lenses you are purchasing come with AR coating or not.
Prescription Lenses and AR Coating
If you wear prescription glasses, it is important to know that AR coating is not always included in the prescription lenses. While some eyewear providers offer AR coating as an add-on option, others include it as a standard feature in their prescription lenses.
It is important to check with your eyewear provider to see if AR coating is included in your prescription lenses or not.
AR Coating and UV Protection
While AR coating does not provide UV protection on its own, it can be combined with UV protection to provide complete protection against harmful UV rays. It is important to ensure that your glasses provide both AR coating and UV protection to ensure complete protection for your eyes.
Maintaining AR Coating
To ensure that the AR coating on your glasses lasts longer, it is important to maintain them properly. Use a microfiber cloth to clean the lenses instead of using tissues or paper towels, as they can scratch the coating.
Avoid using harsh chemicals, such as ammonia or bleach, to clean the lenses as they can damage the coating. Instead, use mild soap and water to clean the lenses. It is also important to store your glasses in a protective case to prevent scratches and damage to the lenses.
AR coating on glasses is a useful technology that improves visibility, reduces eye strain, and enhances the appearance of glasses. It is important to know that not all glasses come with AR coating, and if you need replacement or prescription lenses, it is important to check if they come with AR coating or not.
It is also important to ensure that your glasses provide both AR coating and UV protection to ensure complete protection for your eyes. With this knowledge, you can make an informed decision when purchasing glasses that meet your needs and preferences.
