A Good Pair Of Sunglasses Has Four Main Functions.

- May 10, 2019-

A good pair of sunglasses must have the following four functions:


1.Prevent ultraviolet radiation from sunlight

Ultraviolet rays can damage the cornea and retina, and high-quality sunglasses completely eliminate ultraviolet light.


2.Folding to prevent exposure to strong light

When the eye receives too much light, it naturally shrinks the iris. Once the iris has contracted to its limit, then people need to blink. If the light is still too much, such as the sunlight reflected from the snow, it will damage the retina. High quality sunglasses filter up to 97% of the incoming light to avoid injury.


3.Folding to prevent glare

Some surfaces, such as the water surface, can reflect a lot of light, and the resulting bright spots can disturb the line of sight or hide objects. High-quality sunglasses can completely eliminate such glare using polarizing technology, and we will introduce polarizing technology later.


4.Folding to eliminate light at a specific frequency

Light at certain frequencies blurs the line of sight, while light at other frequencies enhances contrast. Choose the right color for your sunglasses to get the best results in your particular environment.


If the sunglasses don't provide UV protection, it will expose you to more UV light. Cheap sunglasses filter out some of the light, causing your iris to open to receive more light. This will also allow more UV rays to enter, increasing the damage that the UV rays cause to the retina.


Therefore, there is indeed a difference between the various sunglasses. Choosing the right, quality sunglasses will give you maximum protection for your specific environment.
