Science, Creation & EvolutionEvolution vs. Intelligent Design for DummiesGreen, have you ever worn glasses with a yellow lens? In photography (especially B&W photography) a yellow filter is used to intensify light. This is handy if a photographer is attempting to take a picture when the lighting is poor. Using a yellow filter when natural light is bright will over expose the film, and using a yellow filter in glasses in bright light can damage your eyes or at least affect your vision for a period of time. This is what happens with night vision goggles. The "secondary" blind spot is a function of filters used to intensify available light and is not a genetic or "design" defect in the human eye. |
