Everyone wants to look good in their sunglasses, but finding a pair that has the proper UV protection is just as important.
You may not know it, but sunglasses were originally created to aid Navy pilots who were flying at high altitudes. Today there are a multitude of styles and colors to choose from but the main purpose for wearing sunglasses is the same.
The best sunglasses provide 100 percent protection against harmful ultraviolet rays. They prevent ultraviolet rays from penetrating and damaging the cornea. The first sunglasses used glass lenses. The glass was ground using an optical grinder and then treated for UV protection. This provides protection and prevents distortion.
Lenses with distortions can bring on headaches and dizziness for the wearer. So wearing sunglasses with optically ground lenses is important for the clearest vision.
Sunglasses developers have found that glass is naturally resistant to UV rays. Always look for sunglasses that offer adequate sun protection.
Next let's discuss the color or tint of your sunglasses. The best sunglasses are dark enough so that only about 15 percent of sunlight penetrates the lens and reaches the eye.
In tests, developers discovered that glare was a problem for pilots flying at high altitudes. They found that sunglasses that blocked out 85 percent of bright sunlight were the most functional and best for the pilot's vision. So, don't forget to consider the sunglasses' color when picking the right pair for you.
There are many sunglasses to choose from and the decision can be a tough one. You want to pick the pair that flatters you the most but there are other things to consider. To truly serve their purpose, they must be made of optically ground glass with UV protection that blocks out 85 percent of sunlight. The tint is also important. Look for one that only allows 15 percent of light through. If you keep these tips in mind you will keep your eyes safe and look great in your new shades.
