Sunglasses Selection Items

1. The human body has an instinctive reaction to self-protection. When the eyes encounter strong light, the pupils will naturally shrink, reducing the amount of ultraviolet energy entering the eyes. Once wearing glasses without UV protection function, the pupils will enlarge. In addition, these glasses do not have the function of isolating ultraviolet rays. At this time, the eyes are like a wide open door, allowing ultraviolet rays to enter, the harm to the eyes can be imagined.
2. Sunglasses can block ultraviolet rays because a special coating is added to the lenses, while low-quality sunglasses not only cannot block ultraviolet rays, but also seriously reduce the transparency of the lenses, causing the pupils to become larger and a large amount of ultraviolet rays to penetrate, causing damage to the eyes. In addition, inferior lenses can also cause visual fatigue symptoms such as nausea, forgetfulness, and insomnia.
3. The color of sunglasses is superior to light gray, brown, or light smoke, followed by green, amber, blue, etc. Red is only used for sunbathing or snow.
