How to Choose the Perfect Sunglasses?
There are contraindications. Consult your doctor.
Summer is in full swing, and with it comes the bright sun! This time of year brings joy but also requires us to protect ourselves from aggressive sunlight and its ultraviolet radiation. Our eyes particularly need protection, which is why ophthalmologists strongly recommend wearing sunglasses during the spring and summer months.
Choosing sunglasses requires attention and a serious approach. A wrong choice can lead to serious consequences for your eye health. Therefore, it’s important to know how to choose the right model.
Don’t forget that you need to protect yourself from three types of ultraviolet radiation: UV-A, UV-B, and UV-C. Among them, UV-B is the most dangerous type, which can not only cause sunburn but also contribute to the formation of new growths. Unlike the skin, which has a protective mechanism in the form of melanin, the eyes remain defenseless.
So, how to properly choose sunglasses? Let's start with the fact that quality models cannot be too cheap. Therefore, you shouldn't purchase them in transitions, markets, or street kiosks. In such places, sunglasses made from regular tinted plastic are usually sold, which do not provide adequate protection from ultraviolet radiation. Moreover, such sunglasses can lead to pupil dilation, increasing the amount of penetrating ultraviolet light.
It's best to buy sunglasses in specialized optical stores, where you can check the quality and level of ultraviolet protection of sunglasses with special equipment.
What is important to consider when choosing sunglasses in a store? There is an opinion that only sunglasses with glass lenses can provide reliable protection from ultraviolet light. However, modern technology allows plastic lenses to meet this task as well.
Pay attention to the markings on the sunglasses. Quality sunglasses must have labels "UV-A" and "UV-B". If there is a marking "400 nm", it means that the glasses completely block ultraviolet light. At lower values, some radiation may pass through the lenses.
Also, pay attention to the color of the lenses. Gray, brown, and black shades are considered optimal. Gray lenses provide a natural perception of the surrounding world, while brown lenses increase contrast.
Be cautious with sunglasses whose lenses create a blue or violet tint. They can negatively affect your vision in a short period of time. When republishing material, the link to the Source is mandatory!
