Digital Design We live in a world where we are under constant eye strain. Most of our lives are spent looking at computer screens and smart phones. Nikon has created a technology that helps repel harmful blue light to prevent long term eye strain and damage. “These are recurring issues patients have to live with. As a leader in the manufacturing process of high quality lens coatings, we constantly strive to provide treatments that resolve these issues,” said Gravel. “T oday’s reality is that we are surrounded by high energy blue light, more than ever before (LED lights, digital devices, etc).” She noted blocking part of the harmful blue light creates a better visual comfort where eye fatigue is lessened even for those using digital devices all day long. Blue light is emitted from most modern screens built with LED backlights. They remain popular within the technology industry because they are cheap to produce and last longer that old-style CRT screens. The SeeCoat Blue lens improves contrasts, by cutting blue light by 10 per cent while the AR layers still allow near full light transmission. “Several studies tend to prove that cumulative or prolonged exposure to high energy blue light can be dangerous to the retina. SeeCoat Blue should be the number one coating for patients in general to help protect their vision.” The Freeform Revolution For the past few years the eyewear industry has been moving in one clear direction—Freeform lenses. The adaptability and easy wear of this type of lens has made it popular with patients and eyecare providers. Earlier this year Shamir released their Autograph III progressive lens with countless upgrades to address the varying eye issues of patients. “This new technology allows Shamir’s designers to control the power profile of the lens, giving variable emphasis to the power for every given point on the lens,” said Martin Bell, RO and National Sales and Marketing Manager for Shamir Canada. “Autograph III and InTouch incorporate this unique power profile in the corridor to give the wearer a clear and easy-to-reach zone for viewing hand-held digital devices easily and comfortably. With other lenses the wearer has to lower the phone and tilt their head up to see the screen clearly. Now with Autograph III and InTouch, they can see their phone and tablet comfortably” The near viewing zone in Shamir Autograph III is dynamically located within the lens corridor, taking into account the positive or negative power of the prescription. This reduces the need to tilt the head forward or back, or alternatively to lower or raise a book when reading in an attempt to find the right viewing distance and angle. Any postural discomfort is thereby minimized and patients are ensured a comfortably natural posture during near viewing. Plus and negative reading powers move the image that the wearer sees so that the wearer often has to raise or lower their head in order to see clearly. Natural posture relocates this image so that the wearer can read comfortably, in their natural posture. The technology was also incorporated into their line of golf eyewear. When on the links golfers can experience a variety of light factors as the sun m
