Human blinkers

I am somewhat surprised and greatly annoyed that people haven't come up with human blinkers yet. Most home-lighting in the average middle-class homes that I have had the opportunity of being in have tubelights or incandescents lamps with highly divergent light. So they are a terrible pain to the eyes while reading. There is too much directionality to the light and that produces a lot of localised glare that I find very annoying. Of course, I would prefer it if the human blinkers weren't just like horse blinkers. What I prefer is something more like a hollow viewmaster with a head strap. So entrepreneurs, pliss to lissen! (If you want a grander idea and all, try this)
