Compared to some spectacle lenses that you can buy, Noviolenses may seem a bit pricey. However, when you consider all the features that are included with every Noviolens including Plano (0.00 power), and low power non-Rx lenses, as well as Rx Noviolenses, you will appreciate our reasonable pricing. Many lenses that are sold on line and elsewhere have only base lenses, and some add some of the features we include (we do not sell any Noviolenses without ALL the features listed. And all the items listed are not the cheapest available, they are the BEST available.
Here are the features with separate pricing for each item. Note that for insurance claims for our lenses, the separate components usually must be shown with the appropriate HCPCS ( Healthcare Common Procedure Coding System) codes samples of which are included here. An invoice showing the exact codes and their charges will be provided to all purchasers of Noviolens so that they can obtain reimbursement for buying Noviolens from their vision plan. Noviolens will be an "out of network" provider, so check you plan for out of network benefits.
Single Vision (V2101) $30 per lens
Bifocal (V2201) $60 per lens
Mid index lens material (V2782) $30 per lens
UV blocking additive (V2755) $15 per lens
Anti-Reflection coating (V2750) $50 per lens
Anti-Scratch coating (V2760) $ 20 per lens
Anti-smudge hydrophobic top coating (V2799) $30 per lens
Some plans consider some of the above items to be a "luxury" item and will have limited or no reimbursement for some items. At Noviolens, we consider every item to be necessary for safety and comfort, so every Noviolens has all those features. We do not sell any lenses without all the listed features.
If you do the math, you will see that our listed prices for all Noviolenses are less than the totals of the items above. which are our regular pricing when added to existing lenses. Your receipt will be adjusted so the totals match your purchase price for convenient insurance reimbursement.
Some well-meaning manufacturers of spectacle lenses and spectacle lens coatings have introduced lenses that are highly reflective of blue and/or violet wavelengths. They figured that if you reflect blue/violet away from the eyes, that would be protective. While that is true, it is also true that any surface that heavily reflects this HEV (High Energy Visible light) in one direction, also reflects it in the other direction. This means that any HEV coming from behind the wearer is reflected back into the eyes from the front lens surface. Not only that, it is CONCENTRATED on the eye because the front surface is almost always concave toward the eye, like a reflecting telescope!
These lens companies, Hoya, Crizal (Essilor), Zeiss and VSP all have been made aware of this problem, but continue to market these products as Recharge, Prevencia, DuraVision and TechShield. These products are all safe in a completely dark room or outdoors at night. Under all other conditions, they reflect more HEV into the eyes than is reflected by ANY OTHER LENS DESIGN. They uniformly believe that back side illumination is minimal, and does not present a problem. They are flat wrong. It is the very reason that my first patient who tried a Recharge lens could not wear them due to the distracting and DANGEROUS blue reflections he was seeing. Hoya experts claimed that less than 1% of backside lighting can impinge on the lenses. Simple geometry shows that depending on lens size, this can be anywhere from 20% to 30% or more.
To add insult to injury, the lenses mentioned above are hideous. They reflect so strongly that they look terrible and may even pose a threat to others looking at them because of the strong HEV and because of the UV (Ultra Violet radiation) they reflect towards the observer. I call this "second hand blue". Here is an unretouched iPhone picture of someone wearing her Prevencia lenses, facing a large plate glass window in my office:
And here she is 10 seconds later, facing the same window wearing the first Noviolenses ever produced.
Rachel Maddow, Betty Liu, Ashleigh Banfield, Anderson Cooper, Tom Brokaw are you guys impressed or what?
For my first blog entry, I'd like to give some advice as to some simple things people can do to minimize their exposure to HEV (High Energy Visible blue and violet light) and UV (Ultra-Violet radiation).
1. Reduce your exposure by moving the sources (cell phones, computers (tablet, laptops and desktops) as far away from your eyes as is comfortable for you. All radiation, including HEV and UV falls off in intensity by the square of the distance from the source. So if you can double the distance by 2 times, the radiant flux reduces by 4 times. Just moving your cell phone from 4 inches to 12 inches from your eyes reduces the blue and violet flux by 90%!
2. Limit the amount of time you spend looking at video displays. I know this is tough in today's world, but take frequent breaks and go do something healthy like taking a walk, riding a bike or whatever form of exercise you can easily do. You certainly can limit mobile device use by your kids if you have little ones. To avoid interrupting your normal circadian sleep cycles, adults should not use a mobile device within 1 hour of bed time, kids within 2 hours of bedtime.
3. Turn the intensity of radiant flux down on all devices by using the display brightness settings. The only time they should be at full intensity is out in sunlight or in very bright rooms. In a dim room, 25% of max is usually adequate.
4. Reduce the HEV where you can. For computers, this means installing www.f.lux (a quick and easy free app) on all computers and lowering the blue and violet output, especially at night. For all devices, avoid blue, violet and white screens as much as possible. You will notice that when you use f.lux, the white turns a bit yellowish. This is because video displays make white light by using roughly equal amounts of the 3 primary diode colors, red, green and blue. When you remove blue, the predominance of red and green remaining makes yellow. Also, you can change your various "skins" or themes such as desktop backgrounds and google backgrounds to those that have little or no blue, violet or white. Ditch the Microsoft blue sky and cloud scenes in favor of green, yellow, red and orange pictures.
5. Wear Noviolenses.
