How to choose cool glasses

If you decide to buy cool glasses, these instructions will help you determine the choice. Have you ever thought that your eyes also need protection from ultraviolet radiation? Consider the shape of your face when buying this accessory? Did you pay attention to the quality of the materials from which it was made?

Protection

When buying glasses, it is very important to protect the eyes. Excessive exposure to ultraviolet radiation causes a number of problems, such as tearing, burning, cataracts and cancer. Sunglasses should protect against similar risks and block about 99% of the rays of Uvb and up to 95% of Uva. Note whether they pass light on the sides and from above.

Do not buy sunglasses if they are labeled as "cosmetics" or do not provide any information regarding UV protection. Pay attention to the lenses and their coverage, whether it is possible to replace them in case of damage.

Style

Choose an accessory in size. Look for a form that contrasts with the shape of the face.

Stylish women's glasses that have not gone out of fashion for many years now are:

1. Mirror - reflective lenses, popularized by American policemen. Can be in the form of tears or round.
2. Aviators - drops with a thin metal frame.
3. Wanderers - glasses, popular in the 50-60's. Audrey Hepburn wore such a model in the famous film "Breakfast at Tiffany."
4. Round - an accessory that has become an integral part of the stylish image of John Lennon and Ozzy Osbourne.
5. Cat's eye - the name speaks for itself: glasses are elongated.
6. Large - lenses and frames, covering half the face. Such a model is associated with the image of the film star.

The form

Use the shape of your face to choose cool glasses. If you are the owner of an oval face, any style will suit you. With a square shape, you should choose wider glasses with a not too thick frame. Avoid rectangular lenses. Round features balance the polygonal or square frames, which have an angular design. Choose large lenses to change the expression of a gloomy face. Try on darker or brightly colored glasses to highlight the contours of a flat face.

Make sure that they are sitting on you properly. The weight of the accessory should be evenly distributed between the ears and nose. Smile - while cheeks should not raise your glasses.

Colour

The hue of the lens should not only be fashionable, it must meet certain requirements. Pay attention to the contrast of objects: how well the colors differ. Let's say when driving a car you should clearly differentiate the colors of a traffic light. Some cool glasses have interchangeable lenses, you can change their color depending on what you are doing.

Gray lenses reduce the intensity of light without much influence on contrast or distortion. Brown, amber and yellow partially increase the contrast, blocking the blue spectrum. They are good for winter sports, as well as for hunting under bright light. Red or orange lenses are good for winter sports, but only on cloudy days. Purple lenses help hunters see targets on a green background. Copper sunglasses muffle the blue and green spectrum. Blue and green increase the contrast of colors.

Material

Choose lenses that are scratch resistant. Made of polyurethane Nxt - lightweight, durable and expensive. Glass lenses are heavier and less impact resistant. Polycarbonate is not as scratch-resistant as glass or polyurethane, but is more affordable. Acrylic is also suitable, but it is deformed from high temperatures and therefore less durable.

Always wear goggles in a hard case to protect them from damage. Putting a low-quality model, you put your eyes at risk. Remember: cool glasses should not just be beautiful, but also useful. They can both harm your eyes, and save from many troubles, so carefully approach the issue of their choice.
