We have all experienced the annoyance of reflections on our eyeglass lenses. Whether it’s glare from a computer screen or the reflection of a light source, it can cause eye fatigue and make it difficult to see clearly. Thankfully, anti-reflection coatings have become a standard option on spectacles lenses, providing a solution to this common problem.
What is anti-reflection coating
Anti-reflection coatings, also known as MAR or AR coatings, work by reducing the amount of light that is reflected from the surface of the lens. This is achieved by adding a thin layer of material, typically a metal oxide, to the lens surface. The thickness and composition of this layer are carefully controlled to ensure that it interacts with the light in a way that cancels out or minimizes the reflection.
The benefits of anti-reflection coating
- One of the primary benefits of an AR coating is improved visual acuity and contrast. By reducing the amount of reflected light, AR coatings can make it easier to see in a variety of scenarios. This is especially important for people who spend a lot of time on computers or mobile devices, as the glare from these screens can be particularly problematic.
- Another benefit of AR coatings is improved appearance. Without an AR coating, it’s easy to see reflections on the lens surface - the lenses itself look white and your eyes are not visible for someone looking at you or when you look in the mirror you can not see your eyes. Anti-reflection coating makes easier to clean the lenses, because dirt doesn't stick so much to the surface. By reducing reflections from the lens surface your glasses with AR coatings look cleaner and when you take a photo of yourself with glasses on you can see the eyes on the photo - instead white reflections from lenses if the lenses don't have anti-reflection coating.
- Finally, AR coatings can also help to reduce eye strain and fatigue. When light is reflected off the lens surface, it can cause the eyes to work harder to focus. By minimizing these reflections, AR coatings can make it easier for the eyes to relax and focus, reducing strain and fatigue.
While AR coatings have many benefits, it’s important to note that they are not perfect. They can scratch or become damaged over time, and may not be effective in all lighting conditions. However, for most people, the benefits of an AR coating far outweigh any potential drawbacks.
Why anti-reflection coating is so important
In summary, anti-reflection coatings are an essential component of modern glasses lenses. They provide improved visual acuity, a more polished appearance, and reduced eye strain and fatigue. If you wear glasses, consider investing in an AR coating to experience these benefits for yourself. Please contact LENSOMANIA - THE GLAZING LAB and ask about lens coatings we can offer.
