The document compares normal vision to three types of color blindness: protanopia (red blindness), deuteranopia (green blindness), and how different colors appear for each. It includes charts showing how common objects like apples and the American flag appear to those with normal vision versus each type of color blindness. It also lists contact information for Dr. M. R. Ravi, Director of Ahalia Foundation Eye Hospitals in Trichur.
