Nowadays, sunglasses are extremely popular, as they serve not only as a fashion accessory but also as protection for our eyes against bright sunlight. Some people even wear them all year round, as they have become an essential part of their image.
The Importance of Sunglasses
According to ophthalmologists, our eyes suffer not only from infrared and ultraviolet radiation but also from excessively bright light. Prolonged exposure to UV rays can lead to various eye diseases, ranging from lens damage to cancer.
Cosmetologists also recommend wearing sunglasses. In bright light, the eyes remain under constant strain, forcing the pupils to contract significantly. Constant squinting can lead to fine wrinkles around the eyes, which become difficult to remove over time. Wearing sunglasses helps prevent this issue, preserving the smoothness of the skin around the eyes and maintaining the brightness of the iris.
Another interesting fact in favor of sunglasses is that there are special magnetic points on the bridge of the nose. Pressing on these points can help calm a person and reduce aggression.
How to Choose the Right Sunglasses
It is always recommended to buy sunglasses from specialized stores or optical shops, where you can check for a certificate of compliance, verify their quality, and receive a warranty.
Sunglasses should have a shading index ranging from 1 to 4. For example, drivers need an index of 2, while an index of 3 is suitable for city use, vacations, and outdoor activities.
However, the quality of sunglasses is determined not only by their level of tinting. The most crucial factor is the degree of UV protection. High-quality sunglasses should have a label specifying all the necessary information, including the UV protection level, usually indicated as a percentage.
When choosing sunglasses, special attention should be given to the lenses. The most suitable lens colors are dark green, dark gray, and brown. Red lenses can cause eye irritation, while blue and pink lenses, despite their stylish appearance, are harmful—blue lenses do not provide any protection and can distort color perception, whereas pink lenses negatively affect mental well-being. Yellow and orange lenses, on the other hand, are excellent for drivers.
Previously, it was believed that only glass lenses could meet all the necessary standards. However, modern manufacturers now produce high-quality plastic lenses. Their advantages include being lightweight compared to glass, less prone to fogging, and reducing the risk of injury in case of breakage.
