Research and Development

These charts came out of our R&D files, it is a direct numerical breakdown of the products testing chart found on our Wavelength HPS page, showing the spectral filtration capabilities of all the HPS protective eyewear available at the time of testing.

The chart above from our Wavelength ~ HPS page is represented in numerical values in the table below as hard data supporting the superior protective attributes of our proprietary lens compound formulations.

The part of these charts that should be of most interest in regards to the protection of your eyes is primarily the PPF-UV column and secondly the UV-Blue readings. PPF stands for Photosynthetic Photon Flux, which means the measurement how many plant usable photons strike a square meter per second. As you know UV stands for Ultraviolet,, so the PPF-UV column is showing us how many Ultraviolet photons we are being exposed to. The lower the number within this column, the safer your eyes will be. The second part of this chart that should be of concern is the PPF-Blue, which is indicative of the lightwaves within the shorter “blue” end of the visible spectrum. These spectra are also known to cause a host of biological disorders, from permanent eye damage (most cataracts are caused by this spectrum) to hormone imbalances and sleep disorders due to the shutdown of melatonin production, once again, lower numbers in this column are what you want from your eye protection.


As you can see in the table above, Wavelength HPS horticultural protective eyewear beats out all competition, even winning over products that cost nearly triple the price.


Paying for a logo may be fine when shopping for fashion, but not for protecting your vision...the test results speak for themselves, and they clearly say Wavelength.
