Are Darker Sunglasses Better For Your Eyes?

  Do you wear sunglasses when the sun's rays are strong? Are darker sunglasses better for your eyes? What are the key points to consider when choosing sunglasses? There is no necessary connection between the depth of lens color and the protective effect of sunglasses. It does not mean that the darker the color, the stronger the UV protection function. Whether it can protect against ultraviolet rays mainly depends on the functional design of the lens itself. Some lens materials can protect against ultraviolet rays, and some lenses have anti-ultraviolet coatings added to them. Therefore, the main thing is to look at the label to see if the sunglasses comply with relevant standards, and then look for the classification label on it. Lenses are divided into five categories from weak to strong, from 0 to 4, based on their ability to block sunlight and glare. For example, a classification number of 0 means that it only blocks sunlight and glare to a very limited extent, while a classification number of 3 means that it can block sunlight and glare very well. On top of this classification, choose colors based on usage scenarios and personal preferences.
