How do lens coatings work?
In our latest blog, we’ll look at how lens coatings work and what makes them such an impressive technological advancement for your lenses.
Are lens coatings for your glasses really worth it?
If you wear your glasses frequently, you’ll have no doubt experienced smudges, scratches and bothersome reflections at some point. This can interrupt your vision and make even the simplest of tasks much more difficult to complete.
Lens coatings can be an effective solution to help you get more out of your lenses, but what difference can they really make to your glasses?
Improve durability
By applying a lens coating to your glasses, you have a better chance of keeping your lenses in good condition for longer. Lens coatings can make your lenses more robust, delivering additional protection from everyday life. This is often why lens coatings are recommended for children’s glasses who face not only more enemies of clear vision outdoors but are prone to being touched!
Our range of Crizal lens coatings will apply a number of protective qualities to your lenses. These include; scratch-resistancy, smudge-resistancy and dust and water repellency. Having this extra protective layer for your lenses can allow you to enjoy clear vision, without the difficulty of constantly cleaning or replacing them. Resulting in clarity of vision for longer.
Crizal Sapphire UV, Crizal Drive and Crizal Prevencia coatings also carry a scratch-resistant guarantee for 2 years(1).
Enhance visual clarity
One of the most distracting elements of wearing glasses is the unwanted reflections. Reflections can occur on the lenses themselves, or bouncing off of other objects. This can often result in discomfort and the need to adopt new behaviours such as adjusting your head or posture to avoid the reflections.
Lens coatings can provide anti-reflection qualities to reduce reflections and glare when wearing your lenses. This can be particularly convenient for everyday activities such as driving. Crizal Drive can reduce reflections on your lenses, enhancing visual clarity and ensuring you feel safe behind the wheel.
The right lens coating can also help your lenses look invisible to others, improving the aesthetics of your lenses and offering the best in class in transparency.
Provide UV protection
One of the most important things to remember about your eyes is that they need sufficient protection from the sun. Exposure to UV light can have a cumulative effect on your eyes, contributing to eye conditions like cataracts(2).
You should ensure your lenses are providing UV protection in some way. Crizal Sapphire UV provides an E-SPF rating of 35; the highest E-SPF index for clear lenses(3).
This particular lens coating filters UV rays to stop them from passing through the lens, as well as preventing them from reflecting off of the back of the lens.
So, next time you’re wondering how to get more out of your glasses, talk to your optician about Crizal.
