Clear and free of reflections Disturbing reflections of light on the front of the lens, reflections of your own eyes on the back of the lens and rear reflections are annoying. Coating of lenses reduces the reflections. They ensure that you do not get irritated by reflections and improve the transparency of your lenses for significantly improved distinct and clear vision. Top Clean Coat, the top quality coating used in Smaragd Royal prevents fingerprints, dust or grease from sticking to your lenses and interfering with your good vision. The coating also prevents the lenses from getting dirty too quickly. Clear and reflection free lenses provide significantly better vision and appear less conspicuous and more elegant.
