Sunglasses should not be heavy because your ears and nose will not be able handle the weight of the sunglasses for long time and ultimately you have to remove them. The lens of the sunglass should not touch the eye lashes.
Smartly choose your lens color
The lens color of the sunglasses should be chosen properly. Different lens colors go with different atmosphere and so it is necessary to pick up the lens color contrast as per the scenario. Like if wear sunlight shades at night then you will be unable to have vision. And so you need to have different color lens glasses to suit different situations and backgrounds. Now a days sunglasses come with different types of lens with it which can changed as per the demand. So like this, you should choose your sunglasses. It is always better to go for sunglasses pack which contains various interchangeable lenses. Now different colors in lens do different works, like grey color lenses do not affect the contrast or deviate colors but do reduce the color intensity, brown color lenses provides benefits in snow sports and hunting activities since it block some part of blue light, yellow color lenses blocks the major part of blue light and so it is mostly picked up while going for hunting and highly adventurous activities but you should never go for yellow lens while driving because they distorts the color contrast, red lenses are also good for hunters and snow sports person, violet lenses again can be picked by hunters especially when the background is green color, copper color lenses dominate the grass and sky against the golf ball and in the last blue and green color lenses exaggerates the contrast with the yellow tennis ball.
Good quality lens
Now it is very important to check the durability of sunglasses lens. The lenses which can be easily broken or get scratches easily are useless one. You should be careful in choosing good quality sunglasses. Now basically the sunglasses can be of four different materials that is NXT polyurethane, Glass, Polycarbonate and Acrylic. Glass sunglasses are heavy and very expensive and on falling they are broken in spider shape. Polycarbonate is not so expensive material but does not provide clear vision. Along with that scratches can be easily made on such sunglasses. Acrylic material sunglasses are very affordable but they do not provide clear vision at all and they are not durable too. So finally NXT polyurethane material is considered to be the best material for sunglasses lens manufacturing, they resist scratches to a great extent along with that they provide a really vision.
