IS THERE ANY EVIDENCE TO SUGGEST THAT BLUE LIGHT/UV RADIATION CAUSES SIGNIFICANT DAMAGE TO THE EYE?
Light and Eye Damage, Gregory W. Good, O.D., Ph.D. , American Optometric Association, Dec. 2014
Quote: “Blue light damage to the retina has research support from studies with both acute and chronic exposure. Ham et al. (Nature 1976; 260:153-5) first showed that the retina was most sensitive to light at the shorter wavelengths (maximum sensitivity shown at 441 nm) and that retinal damage at the shorter visible wavelengths (up to 500 nm) was primarily photochemical in nature (versus purely thermal effects). This research helped explain the retinal damage seen for those viewing a solar eclipse without proper protection. More recent research has linked long term exposure to sunlight to retinal changes seen in age related macular degeneration. In the Beaver Dam Eye Study, early signs of age related macular degeneration were positively correlated with excessive exposure to sunlight (> 5 hours per day) during the teenage years and beyond (Tomany et al. Arch Ophthalmol 2004;122:246-50). Similarly, in the Chesapeake Bay Watermen Study, late ARMD was positively correlated to cumulative sunlight exposure (Taylor et al. Arch Ophthalmol 1992; 110:99-104). Concerning sunlight and retinal damage, ultraviolet radiation does not appear to be the causative agent as UV is almost totally absorbed by the crystalline lens. Shorter wavelengths of the visible spectrum (i.e. blue-light, 400 to 480 nm), however, show the greatest effects possibly due to photochemical or photoxidative damage in the retinal pigment epithelium ((Taylor et al. Arch Ophthalmol 1992;110:99-104, Roberts. J Photochem Photobiol B. 2001; 64:136-143, and Arnault et al. Plos One 2013; 8:71398).”

Architecture What others had to say
Quirky Gadgets Get Time in Spotlight at Annual Electronics Show - Bloomberg Businessweek, by Ian King, Danielle Burger, Keith Naughton and Lucas Shaw “The goal is to create displays and architectural elements that can be
controlled, effectively letting people change the design of their interiors and buildings with the flick of a switch instead of a paint brush.”
Electric Ink Gives Walls Mood-Changing Color -
Discovery Channel, by Tracey Staedter “You’d program those walls to generate images, messages of encouragement, various animations, colors, etc. Electronic ink
maker, E Ink, is working on just that thing. “I can also be linked to sensors to respond to outside stimuli, like motion. Imagine the possibilities in an office setting. A guest visits and the wall could welcome the individual or group by name. The boss is in a bad mood
and the wall could switch to a more serene, calming turquoise. The lobby could have a new interactive art installation every week.”

Why Do We Still Demand Paper?
It’s more usable
– Only content matters • Create graphs, documents, pictures with no app
necessary
• No learning-curve
– Zero lag-time
– Virtually no physical restrictions (size, mobility, power)
– Easy to read in nearly any environment
– Shatterproof/Rugged
– Total cost of ownership!!!
55
Evolving to the “Paperless Office”
• Vision: sustainable office environment that eliminates the need for paper
Print Everything!!!
Print What’s Needed…
Paper-Lite Lifestyle…
What’s Paper???
Enabling the vision may take years… perhaps decades
