We are all familiar with sunlight, and many of us are aware that sunlight consists of a variety of colours, both visible and invisible to the human eye. Each of these colours represents a different energy wavelength. Most of us should be familiar with the effects of Ultraviolet (UV) rays on our skin. If you have made the mistake of looking directly into the sun, or even snow on a sunny day, you will also be aware of what UV radiation can do to your eyes. But there is another light that is becoming almost as much of a concern, and that is Blue Light.
With all the concern these days about Ultraviolet (UV) rays and the danger to your eyesight, the main concern people have is how to get a good pair of sunglasses. The question is, are all sunglasses created equal? The simple answer to that is no, they are not. Which leads directly to the next question, how do I find a pair that is right for me?

Spring brings with it longer daylight hours and everyone loves a bright, sunny day. The positive effect of sunlight is manifold. Sunshine provides Vitamin D, which is necessary for good health, it warms the air and is very important in the growing process of plants, flowers and trees. It also is great in raising the spirits. Research has shown that sunlight improves a person’s mood and can decrease depression. Unfortunately, the effects of sunlight are not all positive. Ultraviolet light coming from the sun can damage your skin. It can also do damage to your eyesight.
