Introducing REVO LensesLIGHT MANAGEMENT SYSTEM™ (LMS)
REVO lenses manage the full spectrum of light - blocking out the bad and allowing in the good. All REVO lenses are 100% polarized. REVO lenses selectively manage and filter all light in the color spectrum, with emphasis on blue light/HEV light.
• Authentic REVO Mirror Coatings: Developed from NASA technology used on space camera lens coatings, telescopes, satellite protection and space walks, these coatings represent the best in high-tech performance. REVO sunglass lenses feature between 8 and 12 layers of coatings. Backside Anti-Reflective Coatings also eliminate light that can be reflected or bounced off the inside of lenses and back to the eye.
• Authentic REVO Oleophobic Coating: A permanent coating that repels virtually anything - water, oil, sweat, dirt, dust, ink or even a fingerprint.
• Subsurface Protection: Surface scratches can allow UV rays to penetrate through the lens and harm the eyes. Our advanced deep tinting process prevents penetration of UV rays and provides protection to ensure surface scratches do not affect the lens protective performance.
• Lens Materials: REVO uses Serilium™ Lenses - an exclusive lightweight, shatterproof lens formulated of polycarbonate and Crystal Lenses - a higher form of Crown Glass, REVO Crystal lenses are scratch resistant and are ground and polished to about the same standard as a camera lens.
Revolution RXTM Program: The Revo Light Management System™ and Revo High-Contrast Polarization™ technology is now available in an official original equipment RX™ program, delivering the same performance as our signature non-prescription lenses. Revo RX™ features all the benefits of our LMS™ technology including our heritage Revo mirror coatings.
Lighter, Thinner, Sharper, Wiser
Modern lens materials can now reduce the thickness and weight of your lenses whatever your prescription. Special coatings also help to reduce unwanted glare and reflections.
Thinner lenses are made from materials which have a higher refractive index than standard glass or plastic. This means that less lens thickness is needed to achieve the same focusing properties. Modern aspheric designs also mean that the curvature of a lens will be flatter to give a better cosmetic appearance.
There are now many brand name ophthalmic lenses. Some of the manufacturers are well known in the photographic world; NIKON, KODAK, HOYA, ESSILOR and ZEISS. We can supply all these leading brands as well as generic alternatives. We also have an uplink to a most lens manufacturers which enables us to order custom surfaced lenses, ensuring the lens you get is a lens of the optimum thickness for your frames.
There are many brand named ophthalmic lenses available. Our number one supplier is Rodenstock who are the leading manufacturer in designs of the newst forms of both high index materials as well as Free form technology in Multifocal design.As an independent practice though we can offer any of the manufacturers as we are not restrcted by company policies!
Progressive lenses, often called Varifocal lenses, enable clear vision at all distances where a different prescription is required for distance and near vision. Unlike bifocals they have no line to interfere with vision or to give away the fact that you need reading spectacles. Progressive lenses have continued to improve in design over the years to reduce the initial distortion that some people experience with this type of lens and to make them far easier to adapt to. There are nowadays many different designs of progressive lenses, different visual tasks or occupations may be better suited to a particular type of lens. Professional help and advise is the only way to ensure that the right lens is matched to your requirements.
We are now able to offer the very latest IMPRESSIONS® which is the tailored progressive. It is calculated and surfaced individually for you. This ensures that each and every lens retains perfect properties. It is slim, light and elegant, and gives the maximum width reading area combined with near distortion free distance vision, even for those unable to wear progressive lenses in the past.
These are now into their 3rd generation of advanced design -plus the highly successful Nikon Masters Series and the varilux 'S" Series of verifocals now available with special blue filters to help with computer visual stress. (Nikons SEEcoat blue and Essilors Crizaz Prelencia) These filters offer selective protection against harmful blue light- one of the risk factors in retinal cell degeneration-and against UV Rays which contribute to the development of cataracts.
Prevention, such as protecting the eye from harmful light is currently the first line of defence against the worldwide problems of AMD and cataracts. Thes conditions currently effect more than 300 million people around the world a figure that may double in the next 30 years with the ageing population.
Here's Some great advice from leading Lens manufacturer NIKON
Find the right lenses for you
Ophthalmic lens technology has advanced to cater the varying needs of visual correction. There are more than a few types of spectacle lenses to choose from to fit the conditions of wearer’s activities. If you need a spectacle prescription, there are several factors to consider when choosing the right lenses for you; which types of lenses to pick, the materials made in, and some optional coatings to maximize the comfort when wearing.
Step 1. Types of Lenses
The types of lenses you choose depend on whether you want the spectacles to suit all activities or single activity.
Single Vision Lens
If you are under age 40 and need a prescription glasses, then single vision lenses may be sufficient enough for your visual correction. Single vision lenses have the same focal power throughout the lens to provide a single focus.
Progressive Lenses (Multifocal Lenses)
Progressive lenses provide a gradual transition in power within the lens to view all distance from near at hand to far across the room. If you are in your 40s or older and have presbyopia, wearing progressive lenses have an advantage to see all distances clearly without taking the eyeglasses off and on.
Step 2. Lens Materials
Resistant to scratches. However glass lenses are heavy compared to plastic lenses and prone to breakage. It’s not recommended for children or those who are active in sports.
Standard plastic lenses, also known as 1.50 index is the most commonly used material for low pwer prescriptions.
Mid-Index lenses range in material index from 1.53 to 1.56. This material is thinner and lighter than standard plastic lenses. Ask your eye care professional which material will be est for you based on your individual Rx and your selection of frame style.
High-Index lenses are typically have a material index of 1.60. High index lenses are thinner than mid-index and an excellent option for drill mount frames.
Ultra High-Index Plastic
This category of lenses ranges in material index from 1.67 to 1.74, the highest index currently available. Ultra High-Index lenses are the thinnest and lightest materials currently available for higher power prescriptions. Ask your eye care professional what material will be best for you, based on your individual prescription and the frame style you select. Remember, the higher the material index the thinner the lens.
Step 3. About Coatings
Application of coatings provides various benefits for the wearer.
• Anti-reflective coatings help transparency in the lens and glare from various lightings.
• UV coatings protect eyes from absorbing harmful UV rays. Long term exposure can damage DNA and it’s cumulative and irreversible. The UV coating blocks the transmission of light in the ultraviolet spectrum.
• Other optional coatings such as scratch resistance, smudge and water resistant surface applications extend the lifespan of the lenswear.
