Nova-Advance – Back Surface Free-Form PAL
The Advance lens is available in a wide variety of materials and lens treatment options, including polarized and Transitions® lenses.

Nova – Advance
• Uses a universal (semi-soft) blended design that provides ample distance vision and a adequate reading area. It is a good choice for emerging presbyopes, as well as experienced wearers.
• Nova – Advance is ideally suited for all add power prescriptions and most difficult Rx’s.
• Advanced aspheric compensation (measured power) in the intermediate and near zones reduces aberrations providing the best optics for the as-worn position
• Available in three corridor lengths: 10, 12 and 14mm, with three fitting heights, respectively at 14, 16 and 18mm , with variable insets and is a 4 drop lens design.
•
For the highest level of optical performance, Nova-Advance lenses introduce advanced aspheric compensation (AAC) into the intermediate and near visual zones. AAC optimizes the optical performance of the lens in the as-worn position, taking into account eye rotation in relation to the visual and optical axis of the lens.
AAC reduces the aberrations caused by varying vertex distance, while compensating for pantoscopic tilt as the eyes converge from the fitting cross through the reading area. This is a tremendous benefit to patients with difficult prescriptions.

Nova-Petite
A Progressive designed for small and fashionable frames
Sometimes fashion frames are too small for regular progressive lenses and the
wearer is forced to select a bigger frame. Visit the best internet casino MapleLeafOnlineCasino.com! Have good time! Nova-Petite, specially developed for

TRIVEX 1.53 IS NOW AVAILABLE IN THE NEW TRANSITION VANTAGE ADAPTIVE VARIABLE POLARIZED LENSES FROM NOVA OPTICAL LABS–AVAILABLE IN SINGLE VISION, NOVA FOCUS PROGRESSIVE LENSES AND NOVA FOCUS SINGLE VISION FREE-FORM .

The wait is over – you can now get Transitions® Vantage™ lenses from Nova Optical Labs. The revolutionary Transitions Vantage lenses are designed to both darken and polarize upon UV exposure to deliver noticeably crisper, sharper vision, even in the brightest outdoor glare.

The newest addition to the Transitions family of products – Transitions® Vantage™ lenses – are now available exclusively in grey, in Single vision, Nova Focus PAL & Nova Focus Freeform Single vision. Transitions Vantage lenses are everyday photochromic lenses that start out virtually clear and non-polarized indoors; outdoors they not only adapt to changing light but also increase polarization as they darken, optimizing the angle at which light reaches the eyes to help control glare and light scatter.

Transitions Vantage lenses use technology that is different than conventional photochromic and polarization technologies. The photochromic dyes in Transitions Vantage lenses not only darken, but they also align to create polarization. This technology does not use a polarized film, and while the photochromic molecules still change shape when exposed to UV light, they also change alignment. 

   Avaiable now  

CR-39 & Poly —-   Single vision , Nova Focus free form progressives & Nova SV Free-Form

  COMING SOON—Trivex and 1.67index

NOVA OPTICAL LABS continues to search for quality and innovation AND IS ONCE AGAIN MOVING FORWARD in cutting-edge technology for progressive addition lenses. NOVA OPTICALS internal free-form lenses have been available in the market since 2009 and, after years of continual design advances, are now available in two NEW designs. NOVA OPTICALS, 100% back surface designs eliminate the factors that result in non-adapts, with wider, clearer fields of view in all areas of the lens.

Thanks to the recent advances in digital lens processing, you can now offer your patients levels of optical performance that were previously unavailable using conventional technology. NOVA OPTICAL’s internal free-form progressive lens designs are at the cutting edge of ophthalmic lens design, raising free-form digital lens technology to a higher level, with NOVA FOCUS-S & FOCUS-H internal free-form lenses.

Eliminates Distortion-NOVA OPTICALS design is one of the first to use a perfect sphere on the front surface of the lens. Conventional progressive lens designs place or split the power between the front and back surfaces. This elegantly simple, but complex step eliminates the magnification factors that cause virtually all of the swim and sway distortion found in conventional progressive addition lenses. Wearers experience stable, smooth vision throughout the lens, with no annoying distortion.

Wider Fields of View-Advanced software guides the machines used to create a free-form lens. Nova Optical’s software calculates the curves required, taking into account the entire prescription–sphere, cylinder, and axis, add power and prism–and creates a “three-dimensional” map which is then processed onto the back surface of the lens.
One advantage of this design is that the prescription is closer to the wearer’s eye. This is similar to looking through an antique door lock–the closer your eye gets to the keyhole, the more of the next room you can see. 

Progressive lens designs are usually described as being harder or softer, depending on their design and the features they offer the wearer.

A hard design has a more restricted intermediate area, but provides a much wider reading area. A soft design has a wider intermediate area preferred by computer users. The intermediate corridor in a Nova’s internal free-form lens is up to 35% wider than conventional progressive lens designs.

Nova’s advanced software, back surface designs, and know-how creates a totally new type of progressive lenses. First time wearers are amazed by the clear and stable vision and experienced wearers appreciate the extra-wide visual fields–near, far and in-between. 

Optically Precise Rx’s

Older progressive lens designs use only a few base curves; each designed to accommodate a wide range of powers. For each base curve, there is only one optimum spherical Rx at the center of its range. Lens optics is compromised by off-center power error and unwanted astigmatism as you move from the one specific optically precise sphere power.

Nova’s lenses are processed from advanced materials and do not suffer from these base curve limitations. Instead, toric and progressive surfaces are combined and customized to the exact Rx. The wearer receives a truly customized lens with an exact prescription in each area of the lens. Patient accommodation is automatic, as each lens is truly prescription-specific. 

Nova Optical labs is now manufactoring our own digital surfaced product with the installation of the new surfacing equipment in Calgary which is up and running since the end of Oct. Nova has done a lot of researching in new product designs and has introducing two new back surface free form progressive lenses.The Nova Focus-s & Nova Focus-H. Nova Optical is very excited regarding this new lens as it has proven it self to be a very good product.

Nova Optical is very excited about this new investment as it will allow Nova Optical Labs to continue to grow and provide our clients with new technology and better quality products.

What is Trivex

In 2001, Trivex hit the optical marketplace, it was originally developed for the military, as visual armor. PPG Industries took the technology and adapted it for the optical industry. Trivex is a urethane-based pre-polymer. PPG named the material Trivex because of its three main performance properties. The three main properties are superior optics, ultra-lightweight, and extreme strength. Use maple online casino list on mapleleafonlinecasino.com.
Trivex has a high abbe value. Abbe value is a measure of the dispersion or color distortion of light through a lens into its color elements. Abbe number can also be referred to as v-value. The higher the abbe number, the less dispersion, the lower the number, the more dispersion. Trivex has an abbe number of 43-45. This is significantly higher than polycarbonate. Polycarbonate’s abbe number is 30. Trivex has a very high level of light transmittance. The level is 91.4%. This is one of the highest levels of all lens materials. The high percentage is a factor that directly affects the brightness, clarity, and crispness of Trivex.
Trivex has a specific gravity of 1.11. Specific gravity is the weight in grams of one cubic centimeter of the material. Specific gravity is also referred to as density. The higher the number, the more dense, or heavy, a lens material is. Trivex has the lowest specific gravity of any commonly used lens material. This makes Trivex the lightest lens material. Trivex is 16% lighter than CR-39, 25% lighter than 1.66, and 8% lighter than polycarbonate! Trivex has a refractive index of 1.53. This allows for a thinner lens than a CR-39 lens. It can also be surfaced down to a center thickness of 1.0mm. This ability further reduces weight and thickness.
Trivex lenses are strong! They are as strong, or stronger than polycarbonate for impact resistance. Trivex is able to pass the ANSI Z87.1 High Velocity Impact Test. This test is a requirement for safety lenses. The lens must have a center/edge thickness of 2.0mm. The test consists of a mounted lens being subjected to a 1/4-inch steel pellet being hurled at the lens at a velocity of 150ft per second. The FDA also requires lenses to be impact resistant. Their test consists of a 5/8 inch steel ball being dropped from a height of 50 inches onto a lens. Trivex not only passes the test at 2.0mm center thickness, it can even pass the test at a center thickness of 1.0mm. That is tough!
Lenses made from Trivex are very chemical resistant. They are even resistant to acetone. Polycarbonate is not resistant to acetone. Under normal conditions, Trivex is resistant to most commonly used household and optical cleaners and solvents. Cleaners such as Windex and alcohol are safe to use on Trivex.
Trivex lenses due not have the internal stress that is associated with most polycarbonate lenses. This is due to the way Trivex lenses are manufactured. Internal stress can cause lens breakage and is often referred to as birefringence. Birefringence can blur vision. The lack of internal stress makes Trivex a perfect choice for drilled and grooved rimless. Trivex does not crack around drill holes like polycarbonate. These cracks are often called “spider cracks.” Lenses in a drill mount sometimes experience hole elongation. This is due to the flexing and stress that happens to the lens. This can cause lenses to become loose and cause the frame to get out of adjustment. Trivex lenses retain their shape and are not subject to hole elongation.
Trivex lenses provide 100% UV blockage of both UV-A and UV-B radiation. This is inherent in the lens material. Trivex lenses are also very scratch resistant. This is especially important when comparing Trivex and polycarbonate for kids. I have read some literature that puts Trivex’s scratch resistance at twice that of polycarbonate!
I feel that Trivex is an exceptional lens material. We have incorporated it into our lab with fantastic results. It really has so much to offer. I suggest that you try it in your practice. Review the above information and compare it to polycarbonate. I think that if you do, you will come to the conclusion that Trivex is the better lens material to put children into. I think you will find it beneficial for your adult patients as well. I have embraced Trivex and I hope you do as well!
