By now, it's no secret that lenses need protection. From scratches and smudges to glare and dust, lenses can really go through extensive daily wear and tear. It's important to keep your vision clear, and your lenses clearer. But what's the solution?

It Starts with a Premium AR Coat
Shamir’s premium quality AR coating utilizes advanced technologies to provide a cutting-edge, glare-reducing solution for your patients. The basic concept for how anti-reflective coatings work is the optical interference model. Each coating layer in the AR stack combines with previous layers to cancel out a broad range of light waves by introducing destructive interference. Thus, reflective properties of that range of light are neutralized. By applying the principle of optical interference, we can increase light transmission through a lens to nearly 99 percent in most of the spectral range. The result is a reduction of reflections over a broad range of wavelengths and clear, crisp vision for your patients.
Reduce: Even on an AR coating, residual reflections can be distractingly prominent. Shamir’s innovative Low Reflection Finish provides dramatically reduced cosmetic reflections off the lens and reduces visual glare for the wearer, providing a crisp, clear visual experience. Shamir has also addressed a cosmetic issue found on many AR coatings – the “rainbow” effect. To reduce this effect, Glacier PLUS employs Newton Ring Reduction technology (Fig 1) that ensures that the hard coat and AR and lens material are index matched.
Resist: Shamir Glacier PLUS features improved anti-static and scratch resistance properties with a durable surface. By understanding and defining the components for a cohesive bond, Glacier PLUS has greater adhesion to all substrates. (Fig 2) The coating helps lenses resist smears, smudges, dirt, and dust, so they stay clean and enhance visual acuity.
Repel: Developed with oleophobic and hydrophobic properties to enhance your visual acuity, this coating helps to repel dirt, dust, and water, requiring less cleaning and resulting in a longer lasting coating.
The benefits to patients are:
- Improved scratch resistance
- Ease of cleaning
- Enhanced anti-static properties to repel dust and dirt
- Less visual distraction with:
- Reduced birefringence
- More comfortable vision with reduced visual glare, especially for night driving
- Better appearance without distracting and cosmetically unattractive reflections off the front lens surface referred to as ‘cosmetic glare’
Glacier PLUS is available on all Shamir Freeform lenses in Polycarbonate, Hard Resin, Trivex, and 1.67 and 1.60 indices. Lenses come in clear, Transitions, XTRActive, polarized and Blue Zero to suit every patient’s needs.
The Bottom Line
At a time when patients expect more from their lenses, Shamir Glacier PLUS provides a complete package of clarity and comprehensive protection in a state-of-the-art lens. As their trusted eye care provider, ensure that they receive lenses that produce the highest acuity while being easy clean and durable.
For patients who already use AR coatings, Shamir Glacier PLUS can be recommended for a better patient experience. For patients who don’t yet wear AR, it may provide another incentive to choose the enhanced clarity and protection that only premium AR with comprehensive protection can offer.
