Anti-reflective coatings improve both your vision through your lenses and the appearance of your glasses. An anti-reflective coating will eliminate reflections on the lenses, causing the lenses to look thinner or non-existent, which gives you better eye contact with people. An anti-reflective coating can benefit virtually everyone. It improves night vision and decreases eye fatigue with prolonged computer use. Since high-index lenses reflect more light than regular plastic lenses an anti-reflective coating will decrease the reflections, allowing for better vision. An anti-reflective coating will also help to eliminate reflections of sunlight into your eyes from your lenses when applied to the back surface of your sunglasses.   Super HiVision EX3 is the newest anti-reflective coating produced by HOYA vision. Super HiVision EX3 enables 99.5% of the light to pass through the lens and reach your eyes. HOYA matches the index of the coating with the index of the lens material. The lenses and coatings will expand and contract at the same rate, preventing peeling and allowing for extreme scratch resistance. Super HiVision EX3 includes a hydrophobic coating that resists dirt, oil, fingerprints and other distracting smudges.
