HPO Patent Portfolio
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 59 issued global patents and over 17 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.
Industry Problem – Broad Range Filters
While there are many eyeglass lenses with blue blocking filters available in the market, each of these carries with them two inherent problems:
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.
