If you decide to buy cool glasses, these instructions will help you make the right choice. Have you ever thought that your eyes also need protection from ultraviolet radiation? Did you take into account the shape of your face when purchasing this accessory? Did you pay attention to the quality of the materials from which it is made?
Protection
When buying glasses, it is very important to protect your eyes. Excessive exposure to ultraviolet radiation causes a number of problems, such as tearing, burning, cataracts and cancer. Sunglasses should protect against such risks and block about 99% of UVB rays and up to 95% UVA. Notice if they let in light on the sides and top.
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 coating, whether it is possible to replace them in case of damage.
Style
Choose an accessory by size. Look for a shape that contrasts with the shape of the face.
Stylish women's glasses that have not gone out of fashion for many years are:
- Mirrored - reflective lenses popularized by US police. May be in the form of tears or round.
- Aviators - drops with a thin metal frame.
- Wanderers - glasses popular in the 50-60s. Audrey Hepburn wore such a model in the famous film "Breakfast at Tiffany's."
- Round - an accessory that has become an integral part of the stylish image of John Lennon and Ozzy Osbourne.
- Cat's eye - the name speaks for itself: elongated glasses.
- Large - lenses and frames covering half the face. Such a model is associated with the image of a film star.
The form
Use your face shape to choose cool glasses. If you have 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 will balance polygonal or square frames that have an angular design. Choose large lenses to change your frown. Try darker or brighter glasses to highlight the contours of a flat face.
Make sure they are sitting on you properly. The weight of the accessory should be evenly distributed between the ears and nose. Smile - while your cheeks should not raise your glasses.
Color
The shade 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. Suppose, while driving a car, you must clearly differentiate the colors of the traffic light. Some cool glasses have interchangeable lenses, you can change their color depending on what you do.
Gray lenses reduce light intensity without much effect 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 in 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 scratch resistant lenses. Made from Nxt polyurethane - lightweight, durable and expensive. Glass lenses are heavier and less impact resistant. Polycarbonate is not as scratch resistant as glass or polyurethane, but more affordable. Acrylic is also suitable, but it deforms from high temperatures and is therefore less wear resistant.
Always wear glasses in a hard case to protect them from damage. Putting on a low-quality model puts your eyes at risk. Remember: cool glasses should not only be beautiful, but also useful. They can both harm your eyes and save you from many troubles, so carefully approach the question of their choice.
