Functional selection criteria

If the task is to choose glasses for vision correction, functional characteristics are considered first. You should also pay attention to them when choosing protective optics, otherwise the accessory will be just a beautiful item.

Relevant criteria:

• Degree of protection. Models marked with UV-400 protect the eyes as much as possible from exposure to radiation. The lower the value, the weaker the protection level;
• lens material. Glass lenses are less susceptible to mechanical stress, but require careful handling. Plastic is less brittle, but scratches easily. Manufacturers use high-quality polymer materials, which are an excellent alternative to glass;
• The degree of light transmission. The parameter is expressed in numbers from zero to four. Products marked 4 provide the most protection, suitable for trips to the sea, ski resorts. The minimum value is an option for winter, cloudy weather;
• lens color, the parameter affects eye fatigue. Neutral colors are gentle. In lenses of red, orange, the eyes get tired;
• type of protective coating. It can be mirror, photochromic, anti-reflective;
• frame material. Plastic models are light, metal ones are more reliable;
• Lens size. Glasses should securely cover the head not only from the front, but also from the sides.

The CE marking on the frame indicates the certification of the product according to the European standard, it is an indicator of quality. Good glasses are not sold in plastic bags. They are packed in a case, sold through branded outlets or optics stores.

Having decided on the parameters that directly affect the quality of the optics, you can choose the style of glasses. Learn how to choose sunglasses according to your face type.

Glasses and face type

There are basic types of faces that, due to the similarity of shape, are associated with geometric shapes. You can determine your type by visual comparison. Depending on the results, stylists give the following recommendations the correct choice of glasses according to the shape of the face:

• faces with the same proportions in the longitudinal and transverse directions are round. Opposite shapes are suitable for this type: square glasses, "cat's eye", "aviators", models with a narrow nose bridge;
• The owners of oval faces win. This classic shape does not need to be corrected, so the optics are selected based on personal preferences;
• you can soften the angularity, lighten the chin of a square face, using models with rounded edges, not too massive, without a rim;
• faces in the shape of a triangle, turned base down, tapering towards the temples. Proportions can be balanced by large, wide, but not square frames, for example, “aviators” with only bottom rim;
• The heart-shaped face is elongated, has narrow cheekbones and a forehead. This type is suitable for models with low-set temples, round, rounded.

Recommendations are conditional, optics should be selected according to personal preferences and size.

Sunglasses sizes

Manufacturers indicate the size of sunglasses on the inside of the temple. These are four numbers, which, respectively, represent:

• lens width;
• the length of the bridge (the bridge of the glasses covers the bridge of the nose);
• temple length (distance from rim to end);
• Shadow level.

How do I know my sunglasses size? To do this, you can use the dimensions of the previous model, in which it was convenient or make independent measurements. The width of the glasses is measured like this:

• pencils are placed behind the ears;
• the distance between them is measured.

Manufacturers use a standard size grid for branded and sports glasses: 52-54 mm for narrow faces, 58 for standard faces, 60-62 for wide faces.

Size affects the fit of the accessory. Incorrectly selected sun protection optics are not only useless, but also dangerous, as they can cause headaches and fatigue.

How to understand that the glasses are chosen correctly?

Signs of a good fit:

• lack of pressure in the temples, forehead, ears, nose;
• tight fit: the frame must not slip;
• position on a clear horizontal line, without distortions;
• emphasis on the ears and bridge of the nose. The accessory should not rest against the left side of the cheek.

How should glasses fit on the nose? The bridge must strictly correspond in size to the bridge of the nose. To check the correct fit in glasses during fitting, it is recommended to stay for a while. Turning the head, smiling, laughing, other mimic actions should not affect the tightness of the accessory.

So, points are selected. Quality models are expensive, but justify the price. Careful care will extend the life of your sun glasses.

Caring for sun optics

Experts recommend:

• take off and put on glasses, holding the temples with both hands;
• use storage case;
• put lenses up;
• Do not impact, avoid contact with aggressive liquids.

Sunglasses need regular cleaning. Large dirt is washed off with warm water under the tap. You can use soapy water. Then the product is wiped with a napkin, moving along the lens from top to bottom and from left to right without excessive pressure. There is a special spray, after which the lenses do not need to be wiped.
