Scientific research has found blue to be the least appetizing color. This is the basis behind these blue shaded sunglasses. Supposedly, the person who wears these shades sees an ugly hue of blue that brings about a negative view of eating in general. Perhaps the blue tint subconsciously reminds us of rotting food. The end result (hopefully) is the eating of less food and thus, weight loss.
Implications - Research has shown that obesity is a huge problem in today's North American society and is set to be the number one killer within the next decade. The Blue Shade Glasses offer some hope to people who are overweight and could end up being a big help in battling unwanted pounds.
