Lens coatings act as a protective coating for your lenses, transforming modern plastic lenses into strong everyday objects. Unfortunately, lens coatings are often not given the importance they deserve when people purchase a pair of glasses, with wearers pretty much leaving this decision up to the optician. To make sure you’re well-prepared when it comes to anti-reflective, hard, CleanCoat and other coatings, we’ve put together a guide to help you find your way around the maze of coatings. After all, the choice is yours!

Anti-reflective lenses can be recognized by the residual reflection. Regardless of the material used for the lenses, they have a characteristic colour when you hold the glasses at a slight angle against a white background. This is highly practical for the wearer: the optician can identify the anti-reflective coating and even offer the same high quality if a switch to another material is desired.

Lenses without an anti-reflective coating have a great disadvantage:  There is a lot of visible reflection for the wearer. These reflections are particularly distracting on wet roads or when driving at night, but also when talking to someone as that person will see themselves reflected in your glasses rather than look at you.

Special coatings with a hard lacquer matched to the material not only enhance the scratch resistance of the lenses, they also ensure constant visual quality and extend durability.

This is made possible by the way ions seal the lens when the coating is applied.  Read on to find out more.
