But it's the lighting that makes it work. Whether you're drawn to top merchandise in a retail store, feeling safe walking in a brightly lighted area at night, reading a magazine without squinting or sitting in a restaurant feeling romantic, you're under the influence of good lighting. Research demonstrates that 80-85 percent of our impressions of the world come from vision.
Vision requires a functioning eye and light.
It therefore follows that how an environment is lighted can affect our perception of it. The effect is subtle. What we are seeing is what we are seeing. But how we see it is completely dependent on lighting. Dr. Robert Levin is a senior scientist at Osram Sylvania, a lamp manufacturer.
