With the rapid increase of outdoor activities, consideration to the most effective eye protection from the sun must be given. Besides being a fashion statement sunglasses protect the eyes from glare and harmful ultra violet rays.
The actual color of sunglasses is given little attention except if it will match your clothing or personality. However, the color of sunglasses does make a difference to subconscious pathways in your brain. Eyesight is the act of seeing, but vision is the act of giving meaning to perceived information. Thus eyesight is but one of many systems used in visual processing. Part of the eye receptors (the peripheral part) is connected with non-visual pathways in the brain. This includes pathways linked with sleep, memory, emotional and posture centers in the brain. In fact, there are 306 visual connections among 47 of the brain's different sections affecting your health, ability to perform socially, academically and in sports. According to research in Germany, reddish light stimulates the nervous system, triggering activity; lights from blue to violet normally has a sedating effect. Light traveling through colored lenses will bend in different ways depending on color. Grey lenses bend light one-way; brown bends it another way. Also, the location of the center of the glasses makes a difference. A person's neck muscles can be tightened in response to a distorted visual input.Extensive research conducted worldwide, by specialists in visual development and neuroscientists have achieved remarkable progress in the field of vision. Licensed Optometrists or Optometrists specializing in visual development should address any questions you may have concerning glasses.
