A Bright Idea for the Eyes

摘要

The WEstinghouse Lighting Corporation's Eye Saver[TM] Easy Reading Light Bulb is the result of collaboration between Westinghouse, Marshall Research LLC, and NASA's Space Optics Manufacturing Technology Center at Marshall Space Flight Center. The light bulb contains a chrome top that directs light to areas where it is needed most. The bulb, which lasts 2,000 hours, provides 40 percent more surface illumination on work and reading surfaces, compared to a standard incandescent bulb. The lightly frosted finish reduces glare, which helps to reduce eyestrain. The bulb is particularly helpful for people with low vision and eye diseases such as macular degeneration.
