Anti-reflective coating, also known as AR, anti-reflective, non-reflective or anti-reflective coating, can improve your vision. AR coating is added to lenses to reduce glare caused by light striking the back of the lenses. This state-of-the-art invention improves vision and makes your glasses more attractive.
AR coatings virtually eliminate all reflections from the front and back surfaces of the lenses. Without annoying reflections, more light passes through the lenses, optimizing your vision.
Fewer distractions are visible (especially in the dark) and the lenses are barely noticeable. Most people agree that the anti-reflective coating on their glasses is definitely worth the extra cost.
Anti-slip coatings from yesterday
Anti-glare technology has come a long way. A few years ago, AR coatings seemed more of a hindrance than an asset. Past problems have included the constant need for cleaning, peeling of the coating, and frequent scratching.
Due to these past problems, many people tend to avoid them when offered by opticians. They would rather not have to deal with constant problems with their glasses. However, AR coating has seen several improvements in recent years and most people think it is worth it.
New and improved
The new generation of anti-reflective coatings are strong, durable and provide superior vision. The word "cover" is really wrong. Unlike previous versions, the AR coating is actually cast or "baked" into the lens matrix.
Next-generation AR coatings also contain chemicals that make them hydrophobic, which means that the lens surface reduces the adhesion of water and grease. This keeps the lenses clean for longer and makes it easier to clean when they get dirty.
AR coating benefits include:
- Improves vision by reducing annoying reflections, glare and ghosting.
- Improves night vision
- Makes lenses thinner and almost invisible
How does it work
For the first time, AR was developed to improve visibility in high-powered telescopes, microscopes, and camera lenses. An anti-reflective coating consists of several layers of metal oxides applied to the front and sometimes the back of the lens. This layering effect reduces reflected light and allows more light to pass through the lens.
What does this mean for glasses? First, it improves the appearance of your eyes to the outside world. Thanks to the anti-reflective coating, the lenses appear almost invisible. It also significantly improves the appearance of the lenses by reducing internal reflections in the lenses, making the lenses appear much thinner.
Second, it improves the quality of your vision by reducing reflected light. This reduces glare and ghosting around light sources and improves the quality of your vision at night and when using your computer in certain working conditions .
While an AR coating is useful for everyone, it is almost universally found in high refractive index lenses . High refractive index lenses are made of plastic, which can make your lenses much thinner than normal plastic lenses. However, to achieve this fineness, the lens material can sometimes cause unwanted reflections.
As a result, manufacturers who make very high refractive index lenses make AR part of the total cost of the lens and do not separate the lens from the AR coating because they believe that very high index lenses should never be used without the AR coating. .
Choice of AR lenses
The next time you shop for glasses, consider anti-reflective lenses. When choosing anti-reflective coatings, pay particular attention to the rating scale provided by your optician. Some opticians may offer a "good, better, and better" option, and the best rating is significantly more expensive.
Choosing a mid-range or high-end coverage can be worth it. In addition to superior vision, they are also backed by the best warranty and can often be replaced free of charge if your lenses are scratched within a year. Lower cost options generally do not contain the new and improved features described above.
