The organ of Vision

The human eye is nature’s most intricate and delicate organ, and the high degree of development of human society probably rests upon the development of this organ. When nature first developed this intricate and adaptable organism, human eyes were used primarily for outdoor work and living. With the stress of indoor life and artificial lighting, abnormal strain is placed on eyes today. Sometimes more than nature’s assistance is needed to keep eyes in shape for the many uses they serve in modern life. It is also true that we have extended man’s normal lifespan to almost twice what it was in primitive societies. Visual deficiencies also increase with age, and eyes usually need some corrective care as one grows older. Undetected, uncorrected eye trouble can affect the entire personality structure and can make the difference between success and failure in one’s working life or personal relations. Theodore Roosevelt, for instance, was slow and backward till it was discovered that his vision was bad. After his defective sight was corrected, he emerged as one of the leaders of his time.
