When it comes to regular lenses, many factors can negatively affect a person’s vision: glare, UV, and smudges are some of the most common. Also, poor driving conditions, indoor fluorescent lighting, computer screens, and cell phone screens can also increase the chances of experiencing reduced vision.

For individuals that require high clarity in all settings throughout their day, applying an anti-reflective treatment on their glasses will help to eliminate factors that can negatively affect their vision.

If you’ve bought a pair of specs within the last decade, walked by an Optometrists, or watched TV long enough to see any optical commercials, you’ve undoubtedly heard about the anti-reflective coating on glasses.

 


 

So what exactly is an anti-reflective coating, and is it that important to your next pair of glasses?

  • Anti-reflective coating on glasses cuts glare and allows more light through to your eyes. It is a coating that is applied to the surface of your lens. The purpose of this anti-reflective coating is to reduce the amount of glare that reflects off the lens. It allows more light to pass through to your eye, giving you sharper and clearer vision.
  • Anti-reflective coating reduces the appearance of glare on your lenses, allowing people to see your eyes instead of your lenses. Have you ever worn your glasses when someone takes a picture of you? If you saw that picture later, you may have thought, “Hey! Where are my eyes?” Often in photos and specific lighting, the light bouncing off your lenses makes it difficult to see your eyes. Anti-reflective coating on glasses improves how you look wearing glasses by significantly reducing the appearance of glare on your lenses.
  • An anti-reflective coating is proven to reduce eye strain. Because anti-reflective coating on glasses allows more light to pass through to your eye, your eyes can relax while wearing your glasses. Your vision will be more precise and sharper, resulting in less need to strain and focus hard to see.

 

Types of Anti-Reflective Coatings: What Are My Options?

    • Basic Anti-Reflective lenses all come with a scratch-resistant coating (this does not mean scratch-proof) and an anti-reflective coating. This coating helps to reduce glare from night-time driving, but the downside is that these lenses attract dust. This dust combined with the oil from your face is almost impossible to keep your lenses clean.
    • The next level in the anti-reflective coating world is an oil-resistant, hydrophobic coating which, like the basic coating, is scratch-resistant. But unlike the basic anti-reflective, the oil resistance helps keep the oils from your skin off of your lenses, which keeps your glasses much cleaner. And the hydrophobic part means that you’ll get a water-resistant coating. So if, for example, you get caught in the rain, the water will roll right off of your glasses like water rolls off a duck’s back, which will keep your lenses clean from dried watermarks in addition to oil.
    • The Top, this is not only an oil-resistant, hydrophobic coating but also includes multiple layers of scratch-resistance, making it as close to scratchproof as possible. They also have UV protection and are static-resistant (less dust), smudge-resistant, which means less sticky kids’ fingers gunking up your vision!
    • The Tippy Top, That’s right, there’s more! The best anti-reflective coating out there offers your lenses everything that the top of the line has to offer, including a blue coating. What’s special about it? This coating works as a filter to help reduce LED light from electronic devices. That’s right: all those fancy phones, tablets, computers and televisions do strain our eyes, mostly because we use them constantly.

     A study that was conducted by the Pacific University College of Optometry (PUCO) in 2004 aimed to assess the effectiveness of anti-reflective treatment in all settings. The study consisted of 100 participants who wore glasses for more than 6 hours a day, including at least 3 hours in front of a computer. One group of patients wore AR-treated lenses on their new glasses, while another had just a hard coat treatment (scratch resistant treatment). The results showed that 86% of the participants preferred AR treatment in all settings.

    With our busy lives, careers, and our ever-increasing use of technology and blue light, eye strain and fatigue are on the rise. Why not utilise an anti-reflective coating on your glasses to protect your eyes and keep them comfortable?

    Anti-reflective coating on glasses seems to have had mixed reviews in past years. But thanks to cutting-edge technology and progressive thinking, AR has improved by leaps and bounds.
