LIGHT FILTERING TECHNOLOGY

TECHNOLOGY PLATFORM

Protecting the World through Innovation is the foundation for our technology.  Focusing on the protection of the human eye from irreversible damage to the retina from harmful High Energy Visible Light (HEVL) while allowing specific blue light wavelengths  that provide a health benefit to pass to the retina. Selective Filtering is a technology innovation that is changing the eye care industry.

 

HPO holds over 50 issued global patents and over 25 pending global patents.  Our current technology platform remains in a mode of constant growth and development. HPO is structured to identify new market needs with our current and future partners. Once a market need for protection is identified, HPO applies its development platform against those identified needs to create New Patentable Technology that can be applied worldwide.

SOURCES OF BLUE LIGHT

The largest source of blue light is sunlight. In addition, there are many other sources:

 

• Fluorescent lighting

• CFL (compact fluorescent light) bulbs

• LED light

• Flat screen LED televisions

• Computer monitors, smart phones, and tablet screens

 

Blue light exposure from screens is small compared to the amount of exposure from the sun.  Yet, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them. According to a recent NEI-funded study, children’s eyes absorb more blue light than adults from digital device screens.

 

When you stare at a screen for hours at a time, whether it is a computer, TV, phone or tablet, you are exposed to blue light from the device. The discomfort some people have after looking at screens is most likely digital eyestrain. Most of us blink less when looking at screens, causing eye strain and also dry eyes.

 

Blue light does affect the body’s circadian rhythm, our natural wake and sleep cycle. During the day, blue light exposure maintains alertness  and stimulates us. But too much blue light exposure, especially late at night from your phone, tablet or computer can make it harder to get to sleep.

 

 

 

BAD BLUE LIGHT

 

  Essilor - Institut de la Vision-Paris study identified which blue light wavelengths are the most detrimental for RPE cells. The most damaging wavelengths are within the range 435+/- 20 nm.

 

   Sparrow study (Columbia University) identified similar range 430+/-20 nm to be the most harmful for RPE cells.

 

  Several other peer-reviewed studies worldwide have confirmed that these ranges are harmful to the human retina

 

   Shorter blue light wavelengths are of higher energy than the longer blue light wavelengths; e.g. 420 nm light light has higher energy than the 435 nm light; This higher energy is detrimental for the living retinal and skin cells.

 

    The selectivity of HPO filtering to target the most damaging blue light wavelengths yields less unwanted color of the filtering system.

BLUE LIGHT - THE BAD AND THE GOOD

 

Not all blue light is bad. While blue light in the 400-450nm range is harmful, blue light between 450-500nm is considered good blue light and is essential for healthy living. Good blue light boosts alertness, helps memory and cognitive function and elevates mood. It regulates circadian rhythm – the body's natural wake and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. Too much exposure to blue light late at night (through smart phones, tablets, and computers) can disturb the wake and sleep cycle, leading to problems sleeping, daytime tiredness, and chronic health issues.

 

The non-visual functions in humans caused by Good Blue light depend on a newly discovered third photoreceptors (ipRGCs)* containing melanopsin, which form a photoreceptive network across the inner retina. Because melanopsin is so important to the daily resetting of our biological clock, its absorption spectrum is also called the chronobiological spectral band. This band is within the blue range with a peak at about 480nm.

INDUSTRY PROBLEM - BROAD RANGE FILTERS

 

While there a many eyeglass lenses with blue blocking filters available in the market, each of these carries with them two inherent problems:

 

• COLOR: The overwhelming majority of blue blocking optical lenses show a noticeable yellow or amber tint which makes them cosmetically inferior to a more clear lenses.

 

• BLOCKING BOTH BAD AND GOOD BLUE LIGHT: These broad range filters block out the good blue light necessary for controlling our essential circadian sleep cycles.

 

Light filtering technology is commonly used in the ophthalmic industry. However, from a health perspective, today’s ophthalmic lenses currently provide only UV protection (generally below 400nm). The concept of lenses with UV filtering has grown to be a standard for most ophthalmic devices. UV light rays which have wavelengths between 300-400 nm are not visible but damage the human lens and have proven to be a factor in the progression of cataracts. Most eyeglasses, sunglasses, contact lenses, and intraocular lenses provide some level of UV protection.

 

UV blocking eyeglass lenses, contact lenses and intraocular lenses (IOLs) do not offer retina protection from HEVL wavelengths (400-450nm).  Currently, only certain specialized eyeglass lenses sunglasses and IOLs provide HEVL protection, however in many cases there is a noticeable color to the lens hindering cosmesis, reducing daylight vision, night vision and color perception.

 

HPO technology circumvents these unwanted negatives by selectively targeting the most damaging wavelengths of HEVL, which yields superior protection and cosmesis with little to no change in: daylight vision, night vision, and color perception.

 

HPO technology is tunable for various applications and can be incorporated in many materials.
