Particularly topical is the question of how to choose the right sunglasses, it becomes during the active sun, when our eyes without additional protection can suffer greatly. This threat also applies to those who are engaged in winter sports in the mountains. No less important than the degree of protection, is also how well chosen the shape of the glasses according to the shape of your face.
How to choose the right sunglasses by the degree of protection?
The degree of protection of sunglasses lenses consists of two factors: the ability to retard UVA and UVB rays. Do not go too deep into the theory and look for differences in these two types of radiation. It is only necessary to know that both are harmful to the eyes. Therefore, the higher the degree of protection from beams of both wavelengths is indicated on the label attached to the glasses, the higher the degree of protection. Depending on this indicator and your requirements, you can choose from three categories of sunglasses:
- Cosmetic or cosmetic glasses. They pass more than 50% of the rays of both wavelengths. They are not suitable for active sun conditions and perform aesthetic rather than protective function.
- General or universal glasses. Such lenses let in 20% to 50% of harmful UVA and UVB radiation, but if you spend the summer in a city where a large amount of sunlight simply does not reach the ground, then such glasses will be an ideal choice.
- High UV-protection . With such an inscription on the label glasses are produced, the lenses of which have the highest degree of protection. It is worthwhile to get models with such a marking if you want to go on holiday to the sea or, conversely, go to the highlands where the sun is very strongly reflected from the snow cover.

How to choose the right shape of sunglasses?
The choice of sunglasses usually takes place according to the shape of the face, since some types of frames can harmonize its proportions, while others, on the contrary, only underline its imbalance in some parts.
The most harmonious face is oval . People with this face have glasses of any shape, it is only necessary to pay attention to the fact that the frame was equal in width to the widest point of the face. The right choice of sunglasses here is not difficult.

Chubby girls should look for a suitable pair among the glasses of a rectangular or square shape, but now fashionable round glasses are contraindicated. It is also worth paying attention to the design - a massive plastic frame will make the face visually thinner and narrower.

Girls with a heart-shaped face should give preference to glasses with slightly elongated lenses. Ideal for them option - glasses "aviators" or "butterflies", but the square forms do not suit them.

The square face will balance round glasses and the form "aviators". It's good if there is a noticeable plastic frame. But the models that repeat the shape of a person are not their choice.

An elongated face will decorate glasses of almost any shape, but they must necessarily have a noticeable frame, also options with more massive rims on top than the bottom are also suitable. And do not look at these girls glasses without frames or miniature models.

Tips for choosing sunglasses
If you have not decided which sunglasses to choose, then it's worth paying attention to the material from which the lenses are made. They can be plastic or glass. Glass glasses are more expensive and heavy, however, they look more elegant, and the glass itself, without the use of filters, does not allow the sun to pass. Plastic is safer, as it is difficult to break, but it does not detain harmful radiation at all and all the benefits of such glasses are made up of how well the quality filters were applied to cover the plastic base. The undeniable advantage of plastic is its safety. Such glasses will not break, so this material becomes the only one that you can choose if you buy glasses for driving, playing sports or looking for a children's model.
