Lenses
Lenses are the most important element of sunglasses. The degree of protection depends on their quality. They are made of glass or plastic: glass is a more durable material and does not distort the image, but plastic is lighter and cheaper. Modern manufacturers introduce special substances into plastic lenses to increase their durability and degree of protection.
Protection factor
On lenses, as a rule, there is a sticker indicating the protection factor from solar radiation: from 0 to 4, where 0 is a low degree of protection, and 4, accordingly, is the highest.
Color
It is no secret that surrounding colors can affect a person's mood. This effect is enhanced if the color is present in the glasses worn by the person. It is recommended to avoid red-orange tones, which negatively affect the eyes. It is preferable to choose gray-green tones, which will not distort the image but bring it closer to reality.
Important! The opinion that black glasses protect best from the sun is mistaken. If they have a low degree of protection, they will not only not protect from negative solar effects but will also tire the eyes.
Style of glasses
Each person selects accessories based on their taste, but there are some basic rules for choosing glasses. First, if the face has a pointed shape, it is necessary to 'round it out' with a frame of the corresponding shape, and conversely, a round face will suit strict geometric shapes. Second, the upper part of the frame should coincide with the brow line.
Today, there is a huge variety of sunglasses in different colors and styles. For almost any glasses, a blue or yellow frame, made of plastic, wood, or a combined material, will suit. As for summer 2016, this season particularly popular are concise forms, unusual colors, and unisex style.
Despite the fact that, of course, you want to shine in the most fashionable and unusual glasses, you should pay attention to their comfort. The temples should not press, the glasses should not cause discomfort to the eyes, and, of course, they must perform their main function – protection from the sun.
These are the basic recommendations for choosing this accessory. By following them and relying on your taste, you will choose what suits you best.
