MID & HIGH INDEX LENSES
TRANSITIONS ADAPTIVE LENSES
MID & HIGH INDEX LENSES
The introduction of mid and high index lenses allowed for lenses to be made thinner and lighter than with previous materials. The higher the index of refraction of light, the thinner and lighter a lens can be made.
Here are a few types to consider:
Polycarbonate was the first and still the most popular mid index plastic. It is shatter proof and frequently used in children’s eyewear, sports eyewear, and safety eyewear. It is also thinner and lighter than the older version called CR-39 and has the added benefit of improved UV protection.
Trivex is one of the newer materials used for lenses. It is the lightest material used, has shatter resistance equal to polycarbonate, and has better clarity than polycarbonate. It was originally developed for military applications, such as aircraft and helicopter windshields.
High index lenses, such as 1.66, 1.70 & 1.74, are much thinner and lighter than glass, CR-39, or the mid index lenses. As the index of refraction increases, the thickness and weight of the lenses decrease.
No-line progressive lenses provide a smooth transition from focusing on nearby to focusing on distant objects because they do not have a distinct line that separates the focusing powers. Unlike the old bi-focal lenses, progressive lenses have a gradual change in power that helps the wearer to focus on objects at all distances clearly.
If you have had trouble in the past adapting to progressive lenses, or are not happy with the performance of your current pair, give it another try. The newer progressive lenses make it possible to find the right lenses for the best vision.
We offer a range of progressive lenses from the Varilux line, including: Varilux Enhanced. We also represent the amazing Varilux S Series, a true breakthrough in progressive lens technology that virtually eliminates all peripheral distortion. These advanced designs take into account position of wear measurements that further customize and enhance the wearing experience.
OCCUPATIONAL PROGRESSIVE LENSES OR COMPUTER LENSES
Occupational progressive lenses, like Essilor Varilux Computer Lens or Shamir Office Lens, provide clear intermediate viewing at the top of the lens, with extra power at the bottom for reading documents on your desk. No more sore neck from trying to adjust to the computer screen and back to the desk.
The lenses are designed to reduce Computer Vision Syndrome, or CVS, which is characterized by headaches, eye strain, neck and back aches, dry eyes, blurred vision, and double vision.
ANTI-REFLECTIVE COATING (AR)
Nothing can improve the visual and cosmetic performance of your eyewear more than a high quality anti-reflective coating!
Uncoated lenses create glare, reflections, and “ghost images”, which can be especially problematic in hi-index lens materials and for patients wearing rimless eyewear. These problems can all be eliminated with a high quality anti-reflective coating like Crizal.
Features and Benefits include:
Makes the lenses appear almost invisible allowing others to see your eyes, improving the cosmetic appearance of your eyewear
Reduces reflected light and increases light transmission through the lenses to 99.5%
Improves the scratch resistance of the lenses
Reduces glare and halos around lights, improving night vision and when using the computer
Advanced hydrophobic and anti-static coatings resist and repel dust and fingerprints, and allow for easier cleaning
If you have had problems with coatings in the past, know that a high quality anti-reflective coating, like Crizal, can drastically improve the performance of your new eyewear. We offer the Crizal Prevencia. This AR will eliminate up to 25% of the damaging blue light that comes from our electronic devices and 100% of the damaging UV rays from the sun.
TRANSITIONS ADAPTIVE LENSES
If you have ever felt frustrated at needing both prescription glasses and prescription sunglasses to accommodate an outdoor lifestyle, you should consider Transitions® lenses. Transitions®lenses darken when exposed to UV rays. When the wearer goes outside, the lenses darken or tint. When the wearer goes back inside, the glasses become clear. There are a variety of Transitions® lens options available:
Transitions® Adaptive Lenses- Original Transitions lenses quickly adapt between indoor and outdoor conditions, offering a distinct advantage over ordinary clear lenses.
Transitions® XTRActive- They continuously adapt to changing light in all conditions – and by sensing and adjusting to visible light as well as UV light.
Transitions® Vantage- They darken and polarize in bright, outdoor light, combining the technology of original Transitions lenses with variable polarization: polarization that increases as the lenses get darker. This means your vision gets crisper and sharper while color contrast and perception become richer, vibrant and more vivid.
Transitions Signature lenses are now available in a choice of four vibrant new style colors for you to personalize any frames and express your style.
New Colors are: Emerald, Sapphire, Amethyst and Amber
Freestyle your frames with one of our intelligent Transitions XTRActive style mirrors colors, which adapts to any light.
New Style Mirrors: Silver Shadow, Blue, Gold, Green, Pink and Red
